Atomic clocks are incredibly expensive and generally they are normally only to be found in large scale physics laboratories such as MIT (Massachusetts Institute of Technology), NIST (National Institute of Standards and Technology (Colorado) or the National Physical Laboratory in the UK.

Fortunately many national laboratories broadcast the UTC (Coordinated Universal Time) time from their atomic clocks via a radio broadcast.

In the US the national timing broadcast is called WWVB and is broadcast by NIST in Fort Collins, Colorado. The WWVB broadcast is used by millions of people throughout North America to synchronize consumer electronic products like wall clocks, clock radios, and wristwatches. In addition, WWVB is used for high-level applications such as network time synchronization utilizing NTP.

The time code contains the year, day of year, hour, minute, second, and flags that indicate the status of Daylight Saving Time, leap years, and leap seconds.

WWVB broadcasts on 2.5, 5, 10, 15, and 20 MHz and for most users in the United States, the received accuracy should be less than 10 milliseconds (1/100 of a second).

While many NTP servers now use GPS to receive a timing reference, the advantage of using a radio transmission is that a signal can be received indoors (a GPS antenna needs a good view of the sky).

However, the radio signal has a finite range and can be blocked by skyscrapers, mountains and dense conurbations. A radio based NTP server usually consists of a rack-mountable time server, and an antenna, consisting of a ferrite bar inside a plastic enclosure, which receives the radio time and frequency broadcast. The antenna should always be mounted horizontally at a right angle toward the transmission for optimum signal strength.

Similar national timing transmissions are broadcast from other countries in the UK the signal is referred to as MSF and is broadcast by the National Physical Laboratory in Cumbria, other systems are broadcast in Frankfurt, Germany (DCF-77), Japan (JJY) and France (TDF)

All You Ever Wanted To Know About Ebooks / Author: Roberto Sedycias

Many firms which sell online are using dedicated servers as a vital part of their computing infrastructure, a part that is as important as their web domain, their website and the actual products or service they are selling. Server monitoring services are vital for making that these dedicated servers are functioning efficiently.

Dedicated servers are machines for your IT system that you do not have to share. You can run your computer and web hosting systems on them without any other user sharing your server’s resources. People making online payments on websites hosted on dedicated servers will notice the difference compared to a site hosted on a shared server. They will not experience the ‘freezing screen’ situation that you sometimes get with e-commerce websites hosted on shared servers. In these cases the site will not be sufficiently responsive to enable the transaction to go through successfully. There is another situation that sometimes occurs on e-commerce websites that are not hosted on dedicated servers. That is when the transaction will have gone through but the buyer may not be aware that it has because the site has stopped responding. So they will try again so that they end up paying two, three or more times for their purchase. That leaves them with a shock and a problem to sort out further on down the line and is not a good way of creating happy customers. Online merchants who have invested in a dedicated server will benefit from the added assurance of server monitoring services, to alert them of any problems with the service they have bought.

Dedicated servers are an important part of the online retailer’s toolkit because of the security they bring. If you are processing customer orders and handling their financial information you have to be secure. You need to be able to ensure that no-one else can access your stored data and see and download details about your customers. From the customer’s perspective it is reassuring to know that retailers have but measures in place like the use of dedicated servers to ensure that their financial information is being held safely. These kinds of retailers will be in a good position to build a firm customer base and win more customers. One of the worst things that can happen to a firm that sells online is to get their IT systems hacked into and their data stolen with details about their customers bank accounts and credit cards. There will be bad publicity which will reflect badly on the company and put thousands or even millions of people off using them. There may be compensation claims to pay. Server monitoring services go hand in hand with dedicated servers to help reduce these kind of threats.

And there will be the expanse of having to overhaul their IT systems and put protective measures in place. These measures will have to be more rigorous than necessary because the word will be out that their systems are not secure. So the hacker community will be out in force to see what they can get from the unfortunate online retailer. Firms with dedicated servers and server monitoring in place will know they are in a much better position that those with shared servers. Due diligence is important in business, so if something goes wrong, the blame can be deflected from firms that have taken the right precautions in this area.

THE Net headlines this week have been dominated by Viacom’s Round One victory in its legal battle with Google, owners of YouTube, over copy-right infringement.

A judge rules that Google must hand Vicom a 12,000 Gigabyte database recording every time a YouTube clip was watched and by whom. If you watched any YouTube clip, the details will be included. They will not identify you by name, but you’re IP Address and any login name you used will be there.

The one billion dollar claim against Google is for the copyrighted material that users uploaded to the site. Google say it is the fault of those users and that it complies wit the Law by removing illegal material once notified. However, this excuse is a bit thin given that you do not need to try hard at all to see blantant infringements on the site.

For instance, I am writing this Sunday afternoon (13 July 2008), and already I can watch still warm, if grainy, clips of the yet to finish Nadal vs Federer tennis marathon . Broadcasters’ copyrights count for nothing here.

It could yet be that Viacom will seek to use the data in question to go after those who posted their clips on the site. What do you think? Are these YouTube users performing a helpful public service or should the book be thrown at them?

One way or another, this is an important case. The nature of the Net,. The accessibility of Information and the privacy with which we use of it may all be at stake.

Atomic clocks are incredibly expensive and generally they are normally only to be found in large scale physics laboratories such as MIT (Massachusetts Institute of Technology), NIST (National Institute of Standards and Technology (Colorado) or the National Physical Laboratory in the UK.

Fortunately, many national laboratories broadcast the UTC (Coordinated Universal Time) time from their atomic clocks via a radio transmission.

In the UK the national timing broadcast is called MSF and is broadcast by NPL (National Physical Laboratory) in Cumbria. The MSF broadcast is used by throughout the UK and parts of Europe to synchronise consumer electronic products like wall clocks, clock radios, and wristwatches. In addition, MSF is used for high-level applications such as network time synchronisation utilising NTP.

The time code contains the year, day of year, hour, minute, second, and flags that indicate the status of Daylight Saving Time, leap years, and leap seconds.

MSF operates on a frequency of 60 kHz and carries a time and date code that can be received and decoded by a wide range of readily available radio-controlled clocks and provides a received accuracy should be less than 10 milliseconds (1/100 of a second).

While many NTP servers now use GPS to receive a timing reference, the advantage of using a radio transmission is that a signal can be received indoors (a GPS antenna needs a good view of the sky).

However, the radio signal has a finite range and can be blocked by skyscrapers, mountains and dense conurbations. A radio based NTP server usually consists of a rack-mountable time server, and an antenna, consisting of a ferrite bar inside a plastic enclosure, which receives the radio time and frequency broadcast. The antenna should always be mounted horizontally at a right angle toward the transmission for optimum signal strength.

Similar national timing transmissions are broadcast from other countries in the US the signal is referred to as WWVB and is broadcast by the NIST (National Institute for Standards and Technology) in Fort Collins, Colorado, other systems are broadcast in Frankfurt, Germany (DCF-77), Japan (JJY) and France (TDF).

Touch screens have been with us since the early 1970’s but it has only been in the last few years that the technology has expanded into personal applications as well as business.

Traditionally touch screen displays were expensive and only to be found in industrial applications but recent advances and falling cost of technology has meant that the touch screen display is now in everything from the mobile phone and pocket computer to ATM machines and information points.

Touch screens work in one of a number of ways from using infrared to detect the heat of a finger to the more accurate resistive and capacitive touch screens that use an electrical field.

Touch screens have an obvious advantage over conventional monitors in that using a graphical user interface (GUI) and touch screen means that the display can act as both an input and output device so there is no need for a separate keyboard and mouse and their associated wires.

In selecting a touch screen display several questions need to be asked – what tasks will the display be used for, how clear does the monitor need to be, what environment will it be placed in and how responsive does it need to be?

In an industrial environment where the display may have to endure contaminants such as grease, dirt and dust or suffer the risk of getting wet then a sealed capacitive touch screen would be the best option. These are very durable and rugged and many of are manufactured for water and dust resistance (IP56 and IP65).

When more clarity is required from the screen (most touch screens have less illumination than conventional monitors) such as for surgical or medical use then surface wave panel-based touch screen is the better option. These use ultrasound to identify when they are touched and can easily be damaged but they offer better clarity and optical accuracy than other systems.

If a touch screen display is to be left in a public area, unattended or outside then the simplest form of touch screen, the strain gauge, where the screen is spring mounted on the four corners and the movement is measured when the screen is touched, is by far the most durable touch screen display. While they are not as responsive as other types of touch screen they are often used when there is a risk of vandalism.

There are several factors to consider in choosing the best inkjet cartridge for your inkjet printer. These include print quantity, expected print quality, print speed, features, paper type, and the printer to be used—that is, one should identify the need then choose the appropriate one among the different Lexmark inkjet cartridges available to suit that need.

Beginning in the early 90s

Lexmark started as one of IBM’s groups in 1991. Later on, the company went public and detached itself from IBM in 1995. In the process, it had to do away with all the IBM logos printed on its products such as the laser, dot matrix, and inkjet printers. Lexmark became the first company to release a printer in the market that costs below 100 USD. It also made history by being the first to develop printing in 4800 x 1200 and 3600 x 1200 dpi resolutions. Moreover, in the world of photo printing, it pioneered in developing a stand-alone photo printer. Today, reaching over 150 countries, Lexmark is known to be one of the key players in developing, manufacturing, and supplying different printing and imaging solutions including accessories such as inkjet cartridges and copiers. Their products are designed to cater to the varying needs of those customers at home, those running small enterprises, and up to those in large organizations.

Maximizing the use of your printer

In caring for your printer, you should take into consideration the quality of the inkjet cartridge you install. And there is no better solution than buying original Lexmark inkjet cartridges to suit your printing needs. Looking around, you may find lower-priced cartridges that claim to offer the same quality of printing. But keep in mind that once printer-ink compatibility is jeopardized, you are increasing the risk of damaging your printer. At first you may not feel the difference but the amount that you saved from buying the less-reliable cartridges may not be enough to cover the damages your printer may incur in the long run.

To maintain the level of performance of your inkjet printer, you should always install a compatible inkjet cartridge. With the quality and reliability of Lexmark inkjet cartridges, as backed up by the company’s history and reputation, it is the choice if you are going for the best.

Touch screen technology has been with us since the early 1970s and have become increasingly popular in recent years with the advent of mobile phones and pocket computer systems.

Touch screens are now everywhere with ATMs, ticket machines and information points utilizing them. They are a key asset in industrial computing too as touch screen monitors offer certain advantages over conventional computer screens.

The most obvious advantage of touch screen monitors is that they act as both an input and output device. Using a graphical user interface (GUI) there is no need for a separate monitor, keyboard and mouse as the touch screen monitor acts as all three.

In industrial applications, touch screen monitors also have the advantage of being more robust than a conventional CRT (cathode ray tube) or LCD monitor. Touch screens are often built with durability in mind and many are resistant to industrial contaminants such as water, dirt, oil and grease.

Many touch screen monitors boast IP65 and NEMA 4 ratings allowing the monitors to be washed-down and protected against, electrical surges, physical impact, temperature extremes, theft, tampering and airborne debris.

Touch Screen monitors can also reduce the size of a computer system, without separate peripherals and all those wires, they can also be mounted on walls or on the back of machines.

They can also be house in industrial computer enclosures – these afford added protection from spillages, knocks, bangs and even explosive atmospheres. Many touch screen devices are used where standard computer equipment is just not practical such as when a machine is positioned outside or left unattended.

There are different technologies behind touch screen monitors such as resistive touch screens, capacitive systems, infrared and surface acoustic wave technology. The types of touch screen
Differ in their efficiency at reading a touch and the clarity of the monitor. Some of the systems are also more susceptible to scratches and contaminants.

In selecting a touch screen the most important things to remember is where the screen will be placed, what applications it will be used for, how durable does it need to be and how clear or bright does the monitor have to be.

Printers are an essential part of today’s office equipment. Corporations, government bureaus, and nonprofit organizations could no longer function accurately without them. But where there’s a prerequisite for printers, there’s obviously also a necessity for HP toner. Also a printer would be only a box if it had no toner to print to the paper in it!

Lexmark printer cartridges are amongst the most well known manufacturers of printers. Lexmark make use of a two cartridge printing system. The color cartridge is a CMY-cayan, yellow, and magenta cartridge. The black cartridge is purely black. How long they stand will be based on the volume of printing being done. There is an ample variety of things you can do with your PC with suitable applications and your Lexmark printer and ink cartridges. You can generate very professional business presentations including but not limited to graphs, charts, spreadsheets and databases. You can build your own business cards as well.

You can produce a scrapbook. You can get motivation from just about anywhere such as sports, birthdays, weddings, and births. Templates are presented from the internet. Clip art is a great way to add to the beautification of scrapbook pages. You can create frames, backgrounds, borders, and/or journaling.
Photo albums can be shaped as well by means of your Lexmark cartridges. To get the maximum quality photos use photo print paper which is particularly intended to print photos. You will require your Lexmark printer and its cartridges. Get your individual pictures, build up them and you can document your pictures with built in text options. You will need to have a digital camera with a memory card. Capture your pictures and set aside them to a memory card. The memory card is then inserted into the photo printer to print out your photos. To get the best class photos you should use photo paper- the output will be improved. If you are a writer, you will require your PC and as mentioned the suitable applications and your printer. You should use elevated quality paper in standard and/or specialty larger sizes depending on the size of the book. If you are going to plan your own cover you need high-quality card stock paper. You will require a hot glue gun for binding your book.

Fear not, the cuddliest’ time will come when your baby becomes a toddler and begins to seek comfort from the world she can relate to. But in the meantime, if you want to find something for your baby to play with in those brief periods between feeding, sleeping and gurning at you, here are a few pointers:

Safety
You’re probably aware of the need to keep toys with sharp edges or breakable parts away from your child. You’re also most likely aware that many toys carry warning signs because they are unsuitable for under-3s due to being made with small parts. (Parents of children who have passed their third birthday should continue to be cautious if their child has a particular love of chewing everything she picks up).
Look, too, for toys which might have long ties on them which could strangle a baby, or hard and heavy objects which a small baby might drop onto her face when she is laying down.

Age appropriate
Beyond basic safety, most toys for young children come with age-ranges on the packaging. Any toys for children under one year will be safe for your baby to handle, but if they are better suited to babies who can sit up, then don’t push them on a younger child in the hope it will advance their mental stimulation. It is better for your child to find easy amusement than to fail to understand something beyond her ability.

First senses
The earliest toys your child will enjoy are those which contrast shapes and colours. Black and white patterns offer a bold contrast that is appealing to your baby’s developing eyesight and many two-tone mobiles work well, placed at a safe distance from your child’s cot. Bright colours soon begin to stimulate your child, as do simple, sweet sounds. These toys are suitable from birth but will be enjoyed for many months.

Shapes, sound and texture
As babies begin to suck on things other than their mothers’ breasts, and start to appreciate the sensations sending messages to their brains via their fingers, you can introduce textures. Velvety toys with contrasting smooth textures, or soft-edged plastic objects not too big to handle, work well. Toys that crinkle, bells that tinkle and anything which rattles will also appeal. She won’t be able to squeeze with great pressure on a toy yet, but things which squeak or play a simple tune if she chews on them will probably raise a smile.
These toys can be introduced from about three months but don’t feel duty bound to introduce them this early if your child doesn’t show an interest for a few months yet.

Motor skills and hand-eye coordination
When your child can sit up she can enjoy a whole new range of experiences from forces of gravity and movement to spatial awareness and concepts of dimension. Toys with buttons that trigger noises and pictures, and gizmos with holes through which to post things work very well now.
Although you do not want to give your child small toys at this age, when you start to allow her raisins or peas, you will see her begin to pick them up one-by-one. This is valuable coordination practice.
This stage is most likely to be from around seven to nine months but can start earlier.

Imagination and the years to come
In the early years, the stimulation of imaginative play is all-important. From enjoying the link between a fluffy blue dog and the real thing running around a park, to pretending that a heap of cushions is a huge snowy mountain, to the first experiences of interaction through playing ‘tea time’, these things help your child put into practice what they are learning in their daily experience.

What to buy?
You don’t have to rush to the nearest toy shop to stock up on playthings. Your child will love playing with boxes, fabrics and even (safe) kitchen utensils as they pass through these different stages. However, there are companies which specialise in ‘developmental’ toys, taking into account contrasting colours, sounds and shapes.

We currently have three websites our baby product website is www.glimmers.co.uk and our toddler website is www.kidsgosmart.com serve the UK ,with our third site site serving the US market.

What type of toys should I be looking for? / Author: Jack Blue

Many people know Warcraft 3 as a strategy game where skill, micro and knowledge is important. Warcraft 3 is known for its famous players such as 4K.Grubby. However time moves on and the game changes, new maps are developed. Nowadays every active ladder player knows world’s most popular custom map – Defense of the Ancients. It is known as Dota. But why did the game change so much? Blizzard ain’t god and made the changes, neither did it happen by chance. It is in game evolution.

Before I come to my main argument I have to give you an idea of wc3′s complexity. The before mentioned Dota is not only popular because of new heroes and the community behind it, but also because of its completely new game play. A player is directly able to complete with others and to show his skills. If he knows what to do and how to do it he is able to succeed and will win. Statistics can be collected in a third party tool and also be used for a league. Yes.. You heard right, there is already a league for Dota. Electronic sport teams such as Schroet Kommando (sK) see defense of the ancients as a new discipline. Games can be seen on television. Of course, for us normal beings it is very hard to ever reach such skill and to play in world’s top tournaments where the winner obtains thousands of Dollars per successful win, but we can all participate and watch those tournaments online, or even on television. It is almost like watching soccer or football.

But what is the driving force for developers such as Icefrog to make complex Warcraft 3 custom maps? Why are there always new maps such as Wintermaul wars, sheep tag, tree tag or footman? It is quite easy. Blizzard made it possible by inventing an unique, new programming language just for customizing Warcraft 3 maps. Everybody is able to modify maps and make his own, customized versions using the World Editor. What Blizzard did not know, they provided the basics to make in game evolution possible.

Yes, custom maps Darwin’s natural selection have a lot in common. With one exception, there is no sexual intercourse. After modifying a map the players are able to upload/send it to their friend. The easy way is just hosting a Warcraft 3 game and allowing other players to download the map. If the map is good other players will host the map themselves, if it fails, then it will not become popular and will dissappear out of the Battle.net. Good maps are able to evolve and bad ones do not make it beyond the developers hard drive. To put it into a nutshell, good ones establish and bad ones disappear. That’s like in nature, good genes build good survival machines and bad ones die out.

My conclusion is the following: If somebody provides the basics such as in wc3 the World editor, then it seems almost inescapable to prevent selection. So, by playing Warcraft 3 and its custom maps, all of us take part in the complex process of evolution.

What is Trunki Luggage
Trunki is a child-sized suitcase with wheels so that toddlers can ride on it when they get tired during the long walk from gate to gate in the airport. When they aren’t riding, little ones can easily pull the lightweight Trunki suitcase with the pull-strap. Trunki luggage is rugged, fun and solves some common travel problems for families.

Positive points.
Made of the same rugged plastics as adult suitcases.
Pull cord is easy for children or adults to use.
Light enough for toddlers to manage.
Soft rim helps prevent pinched fingers.
Wheels allow children to ride on the suitcase when they are tired.

Not so Positive points.
No outside storage areas – must open up the whole thing to access contents.
Small size means you may not be able to pack as much.

Description
Rolling suitcase for children.
Doubles as a ride-on toy when children get tired.
Approximate dimensions 18″x7.9″x12″. Weighs approx 3.8 lbs.
Recommended for children ages 3-6.
Costs: In the region of £35.
Available in various animal styles, for example cow (Frieda)

Trunki Suitcase
Once kids get into the toddler and preschool phase, they like to have their own things. Carrying one’s own suitcase through the airport becomes significantly less exciting when the child realizes how difficult and tiring that task can be! Trunki, a new child-sized suitcase, makes it easy for toddlers and preschoolers to tote their own carry-on luggage through the airport. When your little one gets tired, Trunki becomes a little ride-on toy that can be pulled along by a parent to give little legs a rest.
One of the things I’ve found about children’s luggage is that it is usually poorly made, too big for little children to manage or prohibitively expensive. Trunki answers all of those complaints quite well. The sturdy suitcase is made with the same durable materials as adult suitcases, so it’s built to last. Trunki is recommended for carry-on luggage only, though, so it’s not a suitcase you’d want to send as checked baggage. The size is perfect for young children. Trunki measures about 18x8x12 inches, and weighs less than 4 pounds when empty. The suitcases are available in pink or blue and have little “horns” for handles on the front. Trunki sells for £33 -£35.

The pull strap is easy to use and the wheels roll smoothly on tile and low-pile carpets. More than one child can actually ride on Trunki, too. The company says the suitcases can hold over 100 lbs. when used as a ride-on!

One of Trunki’s biggest downfalls as carry-on baggage is that there are no outside compartments to keep items that need to be grabbed quickly. You have to open the whole suitcase to get to the contents.

Despite the drawbacks, having a suitcase that your young child can manage is a big plus for Trunki. The ability to let your child ride the suitcase may make your airline travel much easier, and certainly more fun for the child.

ID cards are a very important part of today’s society. They need to be protected so they will last longer and you won’t have to replace them as often. One of the best methods for protecting your identification card would be to laminate it. In fact, laminating ID cards is actually one of the oldest and most popular ways to prevent your card from being damaged. It protects it from being bent as easily and from minor water damage.

There are several different methods available to laminate cards but one of the best and most efficient ways is by using a laminating machine. There are many different designs available that work in a variety of ways depending on how often you would use the device. It would be a good idea to compare the different laminating machines to see what features they have to offer and which one would be the best for your particular needs.

Why Use a Laminator Machine

A laminator makes protecting ID cards easy, convenient and economical. In the past, you had to use laminate sheets to protect your cards. They were difficult to use and they usually wrinkled and puckered making it hard to read the card in these areas. You also had a lot of waste left over that had to be discarded. Separation is a common problem with this method and so you don’t usually get the results you really wanted.

Laminating machines have eliminated these problems. They are efficient and easy to use. The quality is much better and separation is very uncommon. Another big advantage of using a laminate device is to reduce the time and effort used in laminating ID cards. Can you imagine how much time they could save a large company that uses cards on a regular basis? They can be beneficial for smaller companies as well. Usually these employees are multi-tasking many jobs at once, so any device that saves time is a welcome addition to these offices.

Reasons to Laminate

Laminating cards make them more durable so they will last longer even when used regularly. ID cards that are not laminated will rip and tear easily and the ink tends to fade rather quickly when placed in a wallet so they become hard to read. Lamination eliminates these problems and preserves the original form of the card.

Some companies have found that laminating identification badges add to their security because it prevents the badge from being tampered with or altered in anyway. The laminate provides a barrier that will not allow any alterations to be done without making a noticeable change.

Laminating ID cards also makes it possible to punch slots in them so hardware can be attached. This makes it possible for these badges to be worn around the neck, wrist or attached to belts, shirts and so forth. Without laminate protection the card would be too fragile to wear. So as you can see there are many reasons to laminate and excellent devices available to make it faster and easier.

Check out ID Superstore for low prices on a card printer. They also carry many other quality identification supplies, such as all types of id card printer supply and card printer ribbon.

Print Your Own Plastic ID Cards / Author: Lisa Mason

Time is one of the least understood aspects of our universe. We know it exists yet we have trouble grasping exactly what it is. Time can be viewed in two ways, it is a manmade concept used as a tool to describe to explain the sequence of events, comparing the durations and intervals between them.

Time is one of the fundamental quantities which also includes distance, velocity, mass, momentum, energy, and weight and thanks to the work of Einstein and others we know time also makes up the very fabric of our Universe.

Here are ten facts you may or may not have known about time.

10. Time is not a constant; time is relative to different observers. The only constant in the Universe is the speed of light which means no matter how fast you are travelling the speed of light will remain the same although time will slow down.

9. Time can be described as a dimension and along with the other three dimensions we are aware of (up/down, left/right and forward/backward) forms a four dimensional ‘space-time’.

8. Time always moves forward yet many theoretical physicists believe that backwards time travel could be possible.

7. Gravity can warp space-time making time slow down the stronger the gravitational force. Experiments with atomic clocks show the higher above sea level they are (and therefore under less gravitational influence) the faster they run (although the difference is very small).

6. As the speed of light is the only constant in the Universe no matter how fast you travel, light will always seem to be the same speed, this is because time will slow down. A journey at close to the speed of light may seem like a few seconds for a traveler but to an observer it would have taken thousands of years.

5. Time has not always existed. Time started with the big bang and will end if the Universe does.

4. Time can be perceived differently by our brains depending on our activities. A boring day will ‘drag’ on whilst if we are enjoying ourselves time will seem to ‘fly’, this phenomenon is referred to as ‘temporal illusion’ by psychologists.

3. Time appears to accelerate the older we get. Some (including Stephen Hawking) suggest the reason for this is that when we are ten years old a year is a tenth of our whole life and seems a long time, yet for a sixty-year-old a year is just a 60th of their life and therefore perceived as a shorter period.

2. Some modern atomic clocks are so accurate they can lose less than a second in 400 million years.

1. A universal time scale has been developed called UTC (Coordinated Universal Time) which is based on the time told by atomic clocks but compensates for the minute slowing of the Earth’s rotation (caused by the gravity of the Moon) by adding Leap Seconds every year to prevent day from creeping into night (albeit in a millennia or two).

Thanks to atomic clocks and UTC time computer networks all over the world can receive a UTC time source over the Internet, via a national radio transmission or through the GPS network. A NTP server (Network Time Protocol) can synchronise all devices on a network to that time.

Computer speakers or multimedia speakers, as they are better known, are external speakers. The sole purpose they perform is envoicing our Personal Computer. Available with distinct features and quality, these speakers are surely bringing on the time to get heard loud and clear!

These speakers are commonly equipped with a low power internal amplifier. The standard audio connection is a 3.5 mm stereo jack plug often color-coded lime green for computer sound cards. A plug and socket for a two wire coaxial cable is widely used to connect analog audio and video components. There are USB speakers which are powered from 5 volts to 200 milliamps provided by the USB port, allowing half a watt of output power. Computer speakers are present in a wide variety depending on their quality and price. The computer speakers that accompany the computer systems are small plastic boxes with mediocre sound quality. Some of the slightly better ones have equalization features such as bass and treble controls, improving their sound quality to some extent.

The internal amplifiers require an external power source, known as wall-wart. More sophisticated computer speakers may have a sub woofer unit to enhance bass output, and these units usually include the power amplitude and the small satellite speakers. some may even have built-in speakers as well.

Most of the computer speakers are equipped with an LED power indicator, a 3.5 mm headphone jack, controls for volume and sometimes for even bass and treble and a remote volume control. When computers were originally released, they had on board speakers that generated a series of different tone and beeps. As multimedia and games became popular, higher quality sound effects and music. Speakers are generally rated in frequency response, total Harmonic Distortions and watts. Today, good quality speakers are self-powered and equipped with all the latest features. These are relatively small in size to fit on desks or on the side of monitors and contain magnetic shielding.

Adding speakers to one’s computers can increase its functionality and enriches the experience of using it besides adding to the extent of recreation one gets after getting on with them. In today’s world, when we are getting advanced each second, its very hard to imagine using computers without speakers attached to them. The Computer Speakers are essential for the smooth functioning of all the functionalities. Nowadays, there are various speakers like standard, USB and multi-channel etc available and one can choose according to his needs and comforts.

Computer Speakers: Envoicing the Computer / Author: Jacob Marshal

It is a question that has perplexed philosophers and scientists since the dawn of man, ‘what exactly is time?’ and it has only been in our recent history that we have started to discover answers, thanks to Einstein and his work on special and general relativity.

We now know time is not the abstract concept we first thought it was, we also know it is not constant and is relative to different observers throughout the universe with the speed of light being the only constant in the universe.

In other words if the speed of light has to be the same for everybody then someone travelling at close to such a speed would find time slow down.

Fortunately as all humans live within the boundaries of the planet Earth it means the passing of time is very similar for us all (or so minutely different as to be impossible to measure). However, technologies such as satellites and GPS systems have to take into account this altering state of time otherwise they would become wholly inacurate.

As humans have progressed, telling the time with ever increasing accuracy has become more and more important. Historically, knowing the time was not so imperative. People needed to know the correct day to plant crops or when sunrise and sunset happened but accuracy was not a preoccupation.

However, since the invention of the mechanical clock followed at the turn of the twentieth century by electronic clocks, humans have started to rely on more and more accuracy for their technologies.

Seafaring, aviation and now space travel mean that humans have sought more and more accuarte ways of keeping time.

In the 1950’s atomic clocks were developed which were so accurate it was discovered that the revolution of the Earth, something we had based our timescale on for centuries, was no where near as accurate as these new clocks.

Now technologies such as the Internet, the Global Positioning System and satellite communication requires absolute precision as light can travel 300,000 km every second meaning accuracies of a split second could mean our satellite navigation systems could be out by thousands of miles and computer trading would be nigh on impossible.

Fortunately a global time scale, UTC (Coordinated Universal Time), has been developed and is based on the time told by atomic clocks. This allows systems all over the world to be synchronised to the exact same time.

Computer networks use the NTP protocol (Network Time Protocol) to receive a UTC timing reference and synchronise all machines on a network to that time.

NTP servers can receive a time reference over the Internet (although not very secure) from a national radio transmission (as long as the receiver is within range of a suitable transmission) or from the GPS network (via a rooftop GPS antenna).

Network Time Protocol (NTP) is an Internet standard protocol designed over 25 years ago and still under constant development. NTP synchronises devises on a network to a single timing source. If time on a network is not synchronised when applications are conducted over the Internet unintended results can occur such as email being received before it was sent or time sensitive applications failing.

NTP uses a single reference clock to synchronise all clocks on a network to that time. UTC time (Coordinated Universal Time) is the world’s official time standard and most NTP servers are synchronized to receive UTC time. UTC time is kept accurate by a constellation of atomic clocks which ensure that all UTC timing references tell the same time.

NTP is organized into a hierarchy. At the top of the hierarchy are the atomic reference clocks, these are known as stratum 0. Below this strata are servers that receive a timing reference directly from a stratum 0 source. Stratum 2 servers receive time from a stratum 1 server and so on.

NTP is highly scalable meaning a synchronisation network may consist of several reference clocks and NTP will select the best candidates to build its estimate of the current time. This makes NTP highly accurate, with precision of a few hundred nano-seconds not unheard of (nano = 1 second every billion years!)

To synchronise a computer clock to timing reference using NTP extremely simple to do with modern operating systems. Most operating system manufacturers install a version of NTP into their systems (albeit a scaled down version, known as SNTP in some).

This means to connect to an Internet stratum 1 time server a user merely has to insert the domain address in the NTP program. This can be done quite simply in windows by double clicking the system clock and opening up the Internet Time tab. On UNIX the ntp.conf file contains the DNS details.

It should be mentioned that Microsoft, amongst others, recommend using an external hardware source as a timing reference as Internet sources cannot be authenticated leaving a network open to malicious attacks.

An external NTP server can receive a UTC timing signal either through a specialist national radio broadcast (so long as the receiver is within range of a suitable transmission) or from the GPS network (via a GPS antenna).

NTP servers are relatively low cost and easy to install and setup, providing accuracy and precision whilst also offering security.
