Since the introduction of the first compact discs, there wasn’t any storage device so practical and widespread, with many purposes. Compact discs almost immediately replaced the “good old” 3.5” floppy drives, which are still installed in many computer systems today, but no one really uses them anymore.

Floppy discs were practically accidents waiting to happen. The drives themselves were very reliable, but the thin and fragile magnetic discs (basically round audio tapes) were very primitive and unreliable.

The discs were (talking in past tense, because it’s obsolete technology) reasonably well designed, compared to the previous 5.25” solutions.

3.5” floppy discs had one significant advantage over the big floppy discs: the little door cover that opens and closes only inside the floppy drive (although many people accidentally opened them while handling or transport). This was the most floppy discs had to offer, that’s why improved designs were never mass-marketed like the classic 1.44MB version.

Compact discs have set a standard for what we expect from manufacturers. We’re all used to the 12 cm (and 8cm) diameter discs, and it seems that this is the optimal size for optical storage, because bigger optical discs didn’t catch on. This has something to do with desktop case size that can’t house bigger drive units. Imagine a computer case twice as wide as today’s desktop cases, that are already 40 cm x 40 cm x 15cm. It would look almost like a perfect cube because of the large optical drive.

To make a long story short, later DVDs came along with almost 7 times the capacity but the same physical size, and now they are developing bigger and faster Blu-ray burners and players as the main accessories for storing video, audio and all kinds of data.

Sony has always been present in optical drive manufacturing, although some of their drives were re-branded Lite-on and other OEM drives. I had the pleasure of buying a Sony (Lite-on) DVD burner soon after it was released. I chose the cheapest model, which had a $150 price tag and could burn at 4x speed … well sort of … I always used high quality TDK discs, but this DVD burner couldn’t write more than 3-4 disc one after the other. It simply overheated and made very poor quality discs until I let it to cool down at least 30 minutes. I was very happy when it finally broke under warranty, but sadly I later received a 8X Sony DVD burner that was even worse, it kept ruining discs randomly and the firm that sold it to me wouldn’t change it while it was still functioning. To make a long story short, I finally bought an 8X LG burner for approximately $55 one year later and never had problems with writers again, because the technology was significantly improved.

A few years ago Sony entered a partnership with NEC and now they make optical drives together under the name of Optiarc. I have used 18X Optiarc DVD burners for a few years and was very satisfied with burning capabilities, but they all died after 500 discs or so. It will be interesting to see how many discs can be burnt with the new 12X Blu-ray burner BWU-500S, which writes on 25GB and 50GB (dual layer) Blu-ray discs at surprisingly high speeds, while supporting DVD and CD burning too.

The other computer accessory launched was the external Sony BDX-S500U Blu-Ray burner .

It has basically the same specifications except for the maximum reading and writing speeds. These are limited by the interface used (USB 2.0) and maybe other factors too.

Unfortunately this is still new technology and in my opinion these drives shouldn’t be bought yet, because they are very expensive (the discs too) compared to single layer or dual layer DVDs that are much cheaper ($/GB).

A model based on the use

A model of headsets (with headband, earpiece or other) is determined according to its use: sedentary, nomadic or sportive.

Headset’s Impedance
A high impedance on the headsets strongly degrades the power of possible recovery and quality of players. This is the consequence of low power output of these devices. In this case, the headsets should have an impedance below 50 Ω.

Sensitivity and power
The higher the sensitivity of a headset is ,the higher the power of the refund will be.

Headset Amplifier
A headset amplifier allows its use in a system without proper connector. This electronic component also provides a sound quality far superior to the usual home devices.

Cable Length
The cable of a headset is determined according to its use: it is short for a mobile use and long fora domestic use .

Wireless headsets
The wireless headsets are available in various technologies , both in terms of range distance or sensitivity to obstacles.The headsets that cover your ears (circumaural) exist in closed or open models . In addition to rendering sound that varies from one system to another, their main difference lies in a lack of insulation from the external noise ( in the open model example ).

Try before you buy!
Choose a headset while before testing it: the sound can vary from one product to another, more personal help than others, or demonstrate a restitution fine ranging from soft to aggressive.

Custom Headsets
For an uncompromising comfort, tailored tips are possible for in-ear headsets.

The coupling-ear earpiece
The coupling-ear headset has an impact on multiple settings: comfort, sound quality, speaker volume and soundproofing against the outside noise.

Headband
How to wear a headset is the first factor to make a choice. There are different possibilities more or less adapted to the circumstances of use.

The headset includes a headband connecting the earpieces . Although some are as compact as earphones, most of them can be very impressive by allowing maximum audio quality.

The headset resting on the skull, the size of headsets is not a limiting factor. Similarly, the weight ratio is no longer a handicap for comfort. Its disadvantages lie in its compact (very indiscreet and impractical storage for mobile use), the incompatibility during a sportive activity  and for those who care about their hairstyle might find an incovenient in wearing just a headset earpiece.

This is the ultimate mobile headset, compact, discreet, light. It is perfectly suited for sports use if the coupling is intra-atrial, but much less if only semi-intra-atrial. In this case, the earbuds fall out easily. Due to the high compactness of the listener, the sound quality leaves less room than a model with roll. Although it does not have a big physical constraint on the shell and the ear canal, the headset can be uncomfortable or even unbearable for some.

With microphone
These headsets have a purpose for the Internet communication for example or telephones . They are available with round or hoop earrings.

When personal computers were first introduced they were meant to be used separately, without connections to other computers. Later developers realized that in office buildings it’s more advantageous to connect all computers to a huge network in order to share databases, printers, scanners and other accessories. The concept of LAN (local area network) was born. At first it was rather primitive, all computers were connected to a single cable (backbone) that passed by each computer and had terminators on each end. The obvious problem with this network structure was bandwidth sharing. All computers connected to the network received a small part of 10MBPS, the total speed of the network.

Do the math, 10MBPS / 8 = 1.2Megabytes/s, so if there were 100 computers in a single network each received a maximum of 12KB/s bandwidth (in practice it was usually much less). For a while it was enough, because computers didn’t have to handle pictures, audio or video clips yet, but today a 12KB/s network speed is absolutely unacceptable. Even Dial-Up modems exceed this speed. There was one more problem with these networks, they were very hard to maintain, because if the main (single) cable broke the whole network stopped functioning. The same thing happened if a network card burned out, so in general it was very impractical.

Salvation came with the invention of network HUBs. It was a new concept that changed networking forever. Still used today, HUBs (or network switches) connect computers in a star form, meaning that all hubs are connected, but one computer is connected to only one hub, making maintenance a piece of cake. If one HUB or computer failed, the rest of the network wasn’t affected.

In the picture you see a single network cell, but usually many of these network structures are connected with one or even more cables if necessary. HUBs are usually connected in a ring, meaning that each hub is connected to two. This way if a line fails the signal goes the other way around and the network’s activity isn’t interrupted at all.

Imagine HUBs instead of computers. That’s how smaller network cells are connected in ring mode. Besides the extra dependability, the network also receives extra bandwidth with the additional cables connecting hubs together. LAN computer accessories are products that can be used by a larger number of people on a network. They are too expensive to purchase for every computer or it simply doesn’t make sense to have more than a few in a large office building.

In the struggle during the financial crisis, security cams (aka IP CAMs) became very popular in places where supervisors can’t easily see the activities of all employees. Using LAN as video (and/or audio) signal carrier, it’s extremely easy to install a security camera anywhere within 100m of the nearest network hub in the building. They just need a camera support mounted on the wall, an UTP cable and an external power supply plugged into an AC outlet.

The latest IP CAMs come with Wi-Fi support (too) so installation is much easier, but using Wi-Fi also leaves the wired network with fewer privacy issues and with the full bandwidth for office work instead of spying.

LAN computer accessories also come monitor form. Some are designed to monitor network traffic, while others serve as independent workstations while sharing the same computer system connected somewhere to the network.

LG and other manufacturers too came up with this concept when they realized that a lot of power is going to waste when in a school many computers stay in idle. This technology allows 11 monitors to be connected to the same desktop, so only 100-300Watts of power are used instead of 11 x 100-300Watts, while the processing power of any Dual Core desktop is more than enough for 11 people to browse the web, work in MS Office or write programs in any programming language.

There is an abundance of offers for computer keyboards provided by the IT market often leaves us in doubt as to the choice of accessories. The keyboard is one of those accessories where you do not see too much difference. However, many varieties are offered by the market.

So, now, be aware that before any purchase of keyboard, you should check the  sensitivity of the keys, compatibility with the settings on your computer, the keyboard layout you want, with or without wire and many other things.

Choosing a keyboard is often said to be difficult because a wide range is available on the market. Despite their resemblance, the keyboards are not all alike. In fact, they each have their own specificity. First, their interface is not at all the same and the layout of keys on a keyboard may be of AZERTY or QWERTY. Most keyboards on the US market are all type QWERTY. And even if they are all type QWERTY, differences are still outstanding between them. Similarly, the choice of the sensitivity of the keys of a keyboard is very personal because there are some keyboards with keys that are soft and others with stronger keys. Many options can be added to the keyboard, so the choice of a keyboard is not always obvious.

Many keyboard layouts are available on the market. Especially the keyboards USB port that is currently gaining ground, yet the PS2 ports of PCs are more convenient to handle a keyboard. The major disadvantage of USB is the unnecessary use of a USB port. From the point of view also affect the most keyboards supplied by manufacturers are equipped with technology to membrane contactor. And keyboards that have a touch comparable to that of the laptop are also available.

The existing keyboards on the market
Many manufacturers produce several series of accessories such as keyboard. Examples include keyboards, Logitech and Microsoft trademarks that are most recommended because they are safer, thanks to their durability and excellent sensitivity. Among wired keyboards offered by both brands include Logitech UltraX Flat and Microsoft Comfort Curve 2000 very affordable and attractive in their design, discretion and comfort. There is also a wide range of wireless keyboards. Today, wireless technology wins the market and makes it a little more choice when buying a keyboard.

Buying criteria
We sometimes wonder about the shape of the keyboard satisfactory: between that which respects the ergonomics and the keyboard. The main criterion for selecting a keyboard is its ergonomics. These keyboards are slightly rounded with breaks. They are more comfortable and less tiring for the joints because it allows a natural position, starting with the shoulders, through the wrist and ending with the hands.

How to choose a keyboard or wireless? For energy, it is essential to opt for a USB-compatible keyboard. But it is better to use a keyboard to PS2 port for the USB models of recognition is sometimes a problem before starting the system.

Did you know? A bad keyboard, or its misuse can cause musculo-skeletal disorders. This is carpal tunnel syndrome and tennis elbow manifested by numbness, pain in fingers, elbow tendonitis … So the proper choice of a keyboard is very important.

Whenever you read or hear about computer accessories, pink isn’t the first color that comes into mind. At first (when the first personal computers were introduced) no one dared to make accessories in different colors than black, white and other shades in between.

Unfortunately (or fortunately?) as the computer market expanded and all kinds of users were demanding accessories in different colors, forcing manufacturers to abandon classic PC accessory designs, and go for many different colors and shapes.

Some theories emerged recently about the color pink being inappropriate for children. There could be some truth to this hypothesis, but things are a bit more complicated than that. In the early 1900s pink color clothes were perceived to be appropriate for boys and blue for girls, however after 1930 this perception quickly changed. The exact opposite became the norm and it still is today.

Some commentators argue that the obsessive use of the color pink negatively affects the human brain, while psychologists can’t find any significant evidence that would suggest something like that. The truth is probably somewhere in the middle, meaning that not the color itself is harmful, but the way a girl is treated in a family where she’s not only surrounded with pink color toys, wallpapers and clothes, but she is also treated like a girl (with exaggerated femininity). These girls will probably grow up to be very superficial if they don’t reject the pink color at an early age (6 – 10 years old).

Pink computer accessories (or any other pink colored products) are probably safe for everyone, as long as the color is not used obsessively in the person’s surrounding. Today almost anything is available in pink, computers too:

I have to admit that they look a bit disturbing to me, but pink computer accessories are more tolerable if they are small. 

In the picture you see two PowerPoint remote controls, an optical mouse and an external laptop cooling system, these are focused on users on the go, doing product demonstrations or other kinds of presentations.

The Hello Kitty computer microphone is surely aimed at young girls. Just for the fun of it, try to imagine a pink computer and monitor on the following table, placed in a pink room:

You can search all you want, but you won’t find any famous designer putting his/her name on a train wreck like that.

Even in this picture they had to put a lot of brown and white objects to make it look relatively acceptable to the human eye. Personally I have used computer accessories that had black, while, silver and blue parts.

It would be an interesting experiment to try a pink keyboard for more than a few seconds, although there’s no telling what my blogs would look like typed on something like this.

1. A scanning device or a flatbed scanner?  There are several types of scanners, the main being the flatbed, built around a window in A4. To scan only a few passages of text, even a sheetfed scanner pen can suffice, but only to scan a large collection of slides, several models of film scanners exist. The most general format is that of the flatbed scanner, which is suitable for all uses even such as a useful computer accessory.

2. A CCD sensor is better than IRC – There are two types of sensors for scanners, which are included among computer accessories. CIS sensor that is used for entry-level scanners (it costs less and can make products less bulky, self-powered) and the CCD, which it offers better optical quality. It is the latter that we find most on the market.

3. The higher the optical resolution scanner, the greater the result : If a resolution of 600 dots per inch (DPI) is more than enough for most uses, it must also be aware that the bigger, the better you can correctly scan photos, slides or large documents. At 4800 DPI, you are sure of your shot. Caution, do not be fooled by an impressive figure. The manufacturer has been able to put forward an interpolated resolution which corresponds to an improvement in virtual software. Only the optical resolution is valid.

4. Check the sampling rate of the scanner
This measure expressed in bits color depth described a scanner is capable of achieving. The higher the number, the more nuances are numerous and the better the return of a document. A good scanner has a sampling rate of 24 bits at a minimum.

5. The scanner interface is also very important
Completed scanners on parallel port or SCSI. Henceforth, we refer to USB 2.0 or FireWire only. The velocities of these interfaces can quickly scan large documents such as photos A4. Still prefer a USB 2.0, you are sure you can plug into your PC.

6. The speed of scanning is not a true test of choice
Do not trust a model of advertising time of about one minute for text and two minutes for a photo A4. These times “builders” are minimized compared to reality and, in fact, you may wait a while. Then choose a model whose performance announcements are 30 seconds, you’ll maybe just wait a minute.

7. A back-to transparent to scan slides and negatives :The light illuminating the back window “backwards” can scan slides and photographic films 24×36. Without this accessory, you can scan documents as classics such as magazine pages for example.

8. Number of records
Check the number of documents that accepts adapter for slides and films. Some are much smaller than others. The good compromise: an adapter that can accommodate four slides and six poses 24×36.

9. You want to scan many documents? Choose a model with a document feeder.  With it, you easily digitize a series of photographs 10×15: they will be “swallowed” by a by the scanner.  On some high-end models, even professionals, this charger can accept documents in A4 format.

10. Beware of drivers included within the scanner.  They must conform to the way Twain is used by Windows. If so, you can use your scanner as acquisition device through any image editing software for example. In the absence of Twain driver, you must go through the software supplied with the scanner to scan a document or image.

The computer case has undergone a lot of modifications over the years, but a few things never changed. When the first ATX motherboard was developed by Intel in 1995, dimension and cabling standards were set that still stand today, 15 years later. A full size ATX board measures 30.5 cm × 24.4 cm, so a computer case that supports ATX motherboards will support all smaller formats derived from ATX, such as the mATX 24.4 cm  x 24.4 cm, mini-ITX and others.

In 2009 Intel tried to introduce a new standard that’s basically the mirroring of ATX, it’s called BTX. It didn’t quite catch on because it doesn’t really offer any advantages over the format designed back in 1995. To date only a few manufacturers adopted the BTX format for their factory-built systems. Coincidence or not, this way the user can’t change the motherboard of the computer, because only ATX boards are available in stores, so it means some extra profit for the manufacturer’s repair shops.

Most computer case accessories have to do with cooling. The curse of all electronics is that they generate a lot of heat. Without going into details, theoretically almost every application of electronic components is very inefficient. A big part of the power needed for electronic circuits and chips leave in the form of heat, so we can conclude that most of the power isn’t used to get the required result from the circuit, it is simply wasted while it is traveling over mile-long inefficient conductors in the (integrated) circuit.

Although technologies are significantly improving every year, manufacturers didn’t commit to reduce the power consumption of computer hardware to improve efficiency. Instead they agreed upon keeping a power consumption limit for specific components. A desktop processor can consume maximum 140Watts, a graphics card up to 400Watts, an optical drive up to 35Watts … and so on.

The sad part of these applied theories is that computer case accessories can’t keep up with the fast development of other computer hardware parts. The biggest problem is caused by the graphics card, because manufacturers raised the maximum power limit in the last few years, while at first it was only around 40Watts for AGP slot cards. Computer case structure didn’t change that much over the years, but now it has to handle about 10 times more heat.

The single GPU card nVidia Geforce GTX 480 didn’t have a chance with its 250Watt power requirement. As the picture shows temperature goes up to 97 degrees Celsius, not even the biggest case fans can deal with such a heat source.

Manufacturers have even gone to extremes, making one side of the case from a huge fan, but even these noisy extreme solutions can’t cool down a 250-400Watt card by more than a couple of degrees.

Smaller and less powerful systems are the future, which can operate with the smallest coolers, for example the Pentium & Celeron Dual Core processor families E1xxx, E2xxx, E3xxx, E5xxx and E6xxx (or any Athlon II or Phenom II with 45-65Watt TDP), combined with an ATI Radeon 4xxx series card up to 4670 (that doesn’t require extra power cords). Such a configuration might actually function properly with passive cooling on the CPU and GPU, and with only one slow&quiet fan in the power supply that takes out the hot air.

In conclusion you save a lot of money and power if you choose a moderate PC configuration, while buying high-end stuff always leads to heavy electric bills and hundreds of dollars spent on expensive cooling system (possibly even refrigerator-based).

The electronics show Ceatec Japanese general public from last year 2009 was quite interesting  as It was an exhibition of technologies and equipment for medical care and rehabilitation. What was also our surprise and joy to see it all attracted so many people, school children to young mothers, including of course by the elderly and disabled people for whom everything was arranged. Some 110,000 visitors are in fact made it in three days, in the middle of the week. And all the world to put a moment in the situation of individuals dependent or medical staff to experiment with their daily problems and interest of objects specifically designed to alleviate it. In the aging Japanese society that cares more for the handicapped,it is amazing and pleasing at the same time that manufacturers of all sizes, working in areas distant from those of health, specially developed technologies for persons with disabilities, technology that everyone can ultimately benefit from such as computer accessories for handicapped persons.

There were some surprising technologies : devices that allow disabled people to read using a computer or a remote control and communicate better with their surroundings. Example: an amazing voice command system for a computer, among numerous handicapped computer accessories. Everything can be done with words, including very specifically move the pointer on the screen, navigate to the windows, surf the Internet, run software or write. To do this, referring to areas on the edge of screen, the user dictates the vertical and horizontal coordinates where it wants to position the cursor. Then, he commanded the action (click, etc..). The understanding and the accuracy of the system are impressive and one can only congratulate their developers watching a game man totally disabled and diction difficult to recover the smile while testing it.

Other units have the ability to write without hands by choosing the syllabary characters in the head officer of a laser pointer attached to glasses, or as necessary, repeating the action of terminating an automatic listing characters when the correct letter is pronounced to create words and sentences. The trouble is that these commercial products are extremely expensive.

So by the time these equipment will be more accessible to everybody , there are some devices that can help a physically challenged person to operate a computer or at least make it easier.

Convenient to use and extremely easy to mount, the arm rest Ergonoma fits all work plans.
On the ideal positioning on the field office, it contributes to improving the working posture.
The armrest also adjusts Ergonoma all work situations. It will find its place as an administrative position in the workshops or arm laboratoires.Repose Ergonoma. His profile very fluid and large sizes, are the armrests Ergonoma equipment ergonomically very effective because unlike conventional wrist rest that is placed at the keyboard, it provides more support from all of the forearm. Retractable, it is also equipped with a height adjustment screw on a few centimeters.

Advantages:
* Large dimensions: 75 cm

* Fabric Velvet.

However, a child who types in the bath water, or makes a noise and splash can be just as interesting for the development, if not more, because it implies a complete sensory experience.

With careful training, at an early age, our children can live in a balanced way with computers, rather than be dominated by them. The games that introduce phonics, addition and subtraction are abundant.

Clearly, the child used to the achievement of entertainment and amusement only via the computer is less active than the child who can take pleasure in physical activity. While experience in the computer of a child is not followed by ergonomically incorrect posture can develop early, and be difficult to correct later. Parents should also assess the physical effects of using the computer .

If you work at home and share your computer with your children, or if each member of your family has its own PC, special attention is required. Invest in a computer toy is a great way to introduce your child to use the technology they need to use when they get older. Do some research online to find the best computers to children who are proposed. Moreover you can just start from a normal computer and accessorizing it in a way that the child would have fun while operating it : cartoon mice and keyboards, colorful monitors etc …..

And just like in buying  a toy for the kid you have to be carefull what you are choosing for a boy or a girl and be sure you do not buy for example for your girl a spider man mouse and a Hello Kitty for your boy.

And instead of using a regular mouse, you can try this ball rolling. Children are smaller. You can check the size of the child and get the Little Fingers keyboard technology DataDesk.

Also, be sure to check the notice on any computer games that you buy for your child or the game he brings home. There are definitely important factors to be considered before buying any computer program for children. Try to watch the program online to see how it is listed or if the program has the qualities to help your child’s learning development.

Looking for pictures, videos, accessories, or simply practical advice from all sorts of information about these accessories gives general tips and tricks that work best to help you make the best choices possible . The computers, electronic games and toys, and technology in general, have significant influence and affect the lives of children. You can prohibit playback on the computer or watching television for example. Learning can and should be fun! The preschool program provides a fun learning environment for your child .

As technology has improved, many people take advantage of the fact that computer systems are becoming smaller while still managing to perform better and offer more features than the previous, larger model. This can be seen with the large number of notebooks and laptops that are purchased on a daily basis. In fact, more people are now buying laptops than desktops. Laptops, however, will not fail to provide many things because of their small size and they come with some disadvantages that some consumers may not like. In this article, we will compile a list of affordable laptop accessories that will enhance your laptop, so that you do dream of having a better piece of technology.

Wireless Mice
A wireless mouse can be essential to using a laptop. Of course, the notebooks come with a mouse pad, mouse pads, but it may be difficult to use if you have no experience with them. A wireless mouse, on the other hand, is portable and can be used anywhere you take your laptop. A wireless mouse also relieves you of additional cables running in all directions when you use your laptop in public. Wireless mice are not rubber ball as the elderly, were oriented desktop mouse if you can use them on any surface without worrying about traction.

Signal Enhancer
Signal enhancers spend a lot of names, including wireless adapters, signal amplifiers, amplifiers or reception, just to name a few. What these products have in common is they are trying to increase the wireless signal from your laptop without affecting mobility. Your notebook has a wireless adapter and an antenna built into it, but it is often a generic model that is not too good a reception. Buying an external signal enhancer that plugs into a USB port could significantly increase wireless reception in your laptop so you can pick up more networks or simply get a better signal strength for the networks you can already access .

Carrying Case
A laptop bag is a good way to protect your laptop against falls, rain and dust. A carrying case lets you take your laptop with you without having to take on the son or worry about falling. Whether a briefcase, carrying case professionals, or just a bag Glossary Link back normal, so buying a laptop bag constant is a wise investment.  For some reason, mobile phone chargers break a lot. If it is not yet come to you, count yourself one of the lucky ones. Whether the cable, port, or the part that plugs into your computer is at risk, portable chargers do not have much of a life. Thus, it would probably be wise to buy an extra charger for your laptop in the case of the first break. This will at least give you the opportunity to order a replacement without having to go without your laptop for several weeks.

Cooling Pad
Another drawback that laptops and notebooks is that the blower fan is usually not as powerful as you want. Laptops are often overheating that can cause burns, loss of data, or complete computer failure. To avoid this, it would be wise to buy a cooling pad that fits snugly under your notebook and draws heat away from the computer through the use of fans and ventilation systems to double.

Glossary Link Bluetooth Adapter
Many products already or are able to run on Bluetooth technology. Bluetooth allows multiple devices to communicate over a private connection. To send photos, videos, songs and other files on your computer, however, you need to buy a Bluetooth adapter that plugs into the USB port of your laptop.
