Computer Mouse – it’s something you wouldn’t run away from. Instead, it is the one thing you would search for. In fact, every body is in search for a good one. And it has actually become a not-so-easy task to “hunt” for a good mouse – for your pc.

What do you look for, when you say “good computer mouse?” Often, when you buy a whole pc set, a mouse is already included. But there are others who still search for a good one.

In choosing a mouse, you must consider its compatibility with the pc and of course, with you, the user. As the technology advances, there are many types of mice to choose from ranging from mechanical (the ball-inside-type) to optical (ones that use laser to detect movement). Check the connectivity, as there are different mice with different connectivity ports: RS-232C serial port, PS/2 port and the USB.

The cordless (or wireless) mouse uses infrared and Bluetooth devices to receive and send signals. The advantage of cordless mouse is that the user wouldn’t have to deal with messy wires. It is necessary though, for the pc (or laptop notebook) to have a Bluetooth or infrared capabilities. Also, most cordless mouse require batteries to operate.

Use the foot mouse when you do not want your hands to get off the key-board. This unusual idea was prompted by Hunter Digital, for the purpose that both hands can continually work on the keyboard while the foot can simultaneously move the mouse.

The touchpad (or glidepoint) is a usual input device found on laptop notebooks, and portable PCs. This built-in mouse and mouse pad is operated by the fingers gliding along the pad which sends signals to the censors and eventually moves the cursor. Like a normal external mouse, the touchpad also has two buttons which you can click to access icons, buttons and tabs.

The intellimouse, which is also known as the scroll mouse has become the standard mouse that comes along with the PC set. It has a “wheel” in between the two buttons that can be used to scroll up and down on the window. You don’t have to point and drag on the vertical scroll bar which is usually at the side of the window. On some programs, the wheel can be used to open a link in tab.

Normally, the ball of the mouse is found inside the mouse. However, the trackball mouse has the ball on top of the gadget. This reduces the movement of the wrist of the user. The fingers or the thumb are used to move the ball that prompts the cursor to point at an object in the screen.

The trackpoint is another built-in device found in most laptop notebooks and portable PCs. It is a subtle, almost like a pencil eraser isometric joystick located between the letters GH and B. It enables the user to navigate the cursor without removing his hands on the keyboard. The two buttons of this joystick are found under the spacebar.

You must choose a mouse in which you, the user, will comfortable using. It would be best to check for the following in choosing a mouse:

Find a mouse that is as flat as possible and that would fit just right in your palm. This would reduce wrist extension.

Find a mouse that would easily glide as you prompt it. This way, you can reduce tension in your wrist and you can prevent restrictions in the circulation of blood. Remember, it is in your wrist where your pulse is–it should have a relaxed and free flow of blood to avoid injuries.

It is also beneficial to find a mouse that easily be configures to a left or right hand usage. This way, should your other hand be tired, you can shift the work to the other and give the former hand a little rest.

Printer technology has made tremendous advances in the past five years. Speeds are up and print quality is great. Meanwhile, printer costs have declined.

What has not improved is the cost of ink. Printer manufacturers expected to make their profit on replacement cartridges, and they do. But in charging high prices they created another industry that they have to compete with.

Now there are generic or compatible replacements; you can buy refilled cartridges and refill kits so you can refill them yourself. Worst of all there are counterfeits. And there’s a big market for all of them due to the sky-high price of OEM cartridges.

The manufacturers are full of tricks. Some of them use tiny cartridges that don’t hold much ink. Most of the standard cartridges are half full of ink. They sell high capacity cartridges at premium prices that are full of ink. They run promotions on printers that have sample cartridges that barely have enough ink to try out the new printer.

These are all factors you have to consider when you buy a printer. There are makers who have addressed the problem in another way. All printers have a separate black cartridge for obvious reasons, but a few use a separate cartridge for each color. If one of the colors runs out you can replace it individually. This way you aren’t throwing away good ink. One maker gives you the choice of a double size black unit that is more economical than two singles.

Most printers use a cartridge with a built- in print head, but at least one has the print head built into the machine. The cartridges are only ink containers, consequently very inexpensive and easy to refill. The downside of this arrangement is that the print head is a wear item and it’s quite expensive to replace.

The point is that these two style printers are more economical to operate than the conventional type. There are some printers that will operate with only the black cartridge installed, and this is a good choice for students and others that only print text. If you don’t need a fancy printing job, often you can set your printer on “draft” which saves a lot of ink.

Be careful when you are buying a printer especially, but not exclusively at auctions; they’re selling them without ink. A diligent shopper can sometimes find printers with and without rebates that are below the cost of the ink. This is a good way to go. For more information about shopping visit my web site: http://www.caveatemptorus.com/

I’ve tried refilling and using refurbished units with mixed success. Refilling is risky business. Maker’s claim that it voids your warranty, this is debatable, but there is some validity to their concerns. There are different kinds of ink and using the wrong or an inferior ink can do damage. Many refurbs are poor quality so you end up returning them for replacement.

At the moment my choice is a printer with print heads in the cartridges and I buy good quality generics. Keep in mind this creates warranty problems. If you have a problem printing, you can’t get technical service unless you buy a set of OEMs.

Wireless headsets are headphones that are not physically connected to the main device with a wire. These headsets use radio or infrared waves to receive signals from the main source. They provide extremely flexibility to do anything while wearing them-walk, jog, skate or even ski.

Wireless headsets are becoming fairly common even for household use like watching TV or listening to music. Since they are not connected by cords to the main equipment, they allow flexibility to move around and do things like cooking, exercising or any other household chores.

Some wireless headsets use infrared rays for receiving signals, like a remote control. These have a limited range of receiving of a maximum of 30 feet. Cordless headphones, on the other hand, use radio waves. The headset should be adjusted in frequency with the base station so as not to interfere with other devices. These headsets have a greater frequency of up to 2.4 GHz and can reach up to 300 feet.

When buying a wireless headset consider the following: is it comfortable? Does it stay securely in place for long hours? Is the microphone flexible and unobtrusive? Are the volume and other controls easily accessible? Is the sound quality on both the lines clear?

Most wireless headsets these days come with advanced features like standard/voice tube/ noise canceling, the solution type (telephone use/ mobile use/ headset adapter/headset accessory), the kind of ear piece (monaural/binaural), the kind of phone or computer connection to be used with the headset (Bluetooth, USB, 3.5mm/ Analog), the compatibility (to music), the kind of computer usage (VoIP, Computer Gaming), the range of bass/treble, the speaker power, etc. The kind of battery should also be considered since the length of use is dependent on the strength of the battery. Some wireless headsets use rechargeable batteries.

The leading manufacturers of wireless headsets are Plantronics, GN Netcom, Headsets.com, Sennheiser, Jabra, and Sony. The Internet is a good source for locating the ideal wireless headset. There are several web sites that provide comprehensive information about the wide range of wireless headsets available in the market today. Manufacturers also provide the support of online specialists to help you select the best headset, including discounts and warranties.

Headsets provides detailed information about headsets, wireless headsets, phone headsets, aviation headsets and more. Headsets is the sister site of Free Phone Conferencing.

Who needs an LCD display? Well, if you’re like me, having one huge hunk of a monitor sitting on your desktop is just not feasible. Not only does it take up desk space, but there’s just simply no need for all of the physical mass, right?

Welcome LCD displays—the computer monitors of the present and future. From year to year these computer peripherals tend to get smaller and thinner in size with twice the power and benefits. Well, stay on the look out for more to come because I am certain that our current flat monitors have not reached their journey’s end yet. An LCD (which stands for liquid crystal display, by the way) works much differently than your CRT, mostly because they don’t project light, and therefore use much smaller units during display.

Let’s talk about the benefits of a flat monitor:

1.) They produce less heat

2.) They use less electricity

3.) Because they use digital signals, the display is sharper and clean

4.) Speakers are generally included in the screen, so you don’t have to worry about cluttering your desk with speakers anymore

When deciding on purchasing your LCD display, be prepared to spend at least $200, and definitely look into a 19 inch display (as opposed to a 17 inch). From Sam’s Club to Sears to Circuit City, it’s certain that you’ll find the display you need for the price you want to pay. Just do a little comparison shopping, and pat yourself on the back for making a purchase that will clear up your desk clutter and save you some space!

Headsets, also known as headphones, are hearing devices that are actually miniature speaker systems. They are stereo hearing systems that can be worn near the ear, thus providing mobility to the user. Traditional headsets were bulky and large with two speakers for both the ears encased in padded ovular ear cups. These ear cups were attached to a headband in the shape of an arch that went over the head. Each of these ear cups had a signal wire joined down together as a single wire, which was connected to the audio player or radio through a headphone jack.

Today’s headsets, especially radio headsets, are technological wonders-extremely lightweight with no irritating cords, almost negligible in appearance, sound quality, durability and comfort. They are equipped with superior technologies like push-to-talk and duplex wireless transceivers. These can transmit scrambled digital signals in a spread spectrum format for ensuring complete security and privacy to the user. Radio headsets also have the noise cancellation option for better acoustics.

Radio wireless headsets have wider ranges of up to 300 feet or 90 meters. They use frequencies of 2.4GHz and can be receive transmission even through walls. Sound quality, speaker power, bass and treble range are some features to look for in a radio headset. Other options are the accessibility of the controls like volume and frequency. The battery is also important as the total cost of ownership depends on the batteries. Some radio headphones use rechargeable batteries. The style and comfort are other factors to be considered while buying a radio headset.

There are several manufacturers of radio headsets like David Clark, BHI, Kenwood, Warren Gregoire and others. The Internet is the best source to find out more about buying a radio headset. There are many websites that provide information about the products, along with other offers, discounts and warranties. A good radio headset is around $30, though it varies according to model.

You are working at your computer and trying to print out important documents and all at once you find you are out of ink. Years ago that would have presented a big problem. Printers used ribbons or daisy wheels to print on paper. Let’s take a look at the evolution of printer ink cartridges.

In 1984 ink jet printers and printer cartridges were introduced. Printing documents was now easier and so was changing printer cartridges. After years of changing ribbons, adding toner ink to reservoirs within the computer.

The dot matrix method used a ribbon. The industry found new ways to make printing easier and more convenient. There is the drop on demand method where the ink squirts onto the paper through tiny nozzles. The amount of ink dropped the page is controlled by the software driver that controls which nozzle fires and when.

By 1990 ink jet print cartridges was widely accepted. Printer cartridges can now print in color as well as in black and white for document. Inkjet printer cartridges can print on just about any sized paper, on fabric and on film. Ink jet printers are used in a variety of settings worldwide and is a popular choice for printing.

Each brand of printer uses a specific type of cartridge. Ink jet cartridges are given an identification number and the models that can use this particular cartridge, is listed. There are a wide variety of cartridges available and you should check your printer’s manual to see exactly what cartridges are available to you.

If you are trying to save money, you can purchase refill kits that allow you to fill the cartridges yourself. Not everyone is a fan of these kits however, the quality of the printing isn’t as good, and in some cases the cartridges when re-installed can fail to operate.

You can get reconditioned and refilled cartridges from some retailers and sometimes from the manufacturer. Compatible cartridges are cartridges that are made according to the exact specs of the original manufacturer. The drawback here is that not every cartridge has a compatible one.

In choosing a printer check the type of cartridge it will use. You will need to determine if the cartridge is appropriate for the type of printing and the volume of printing you will be doing. You will have to do some research and you can find much of this information on the internet, through the manufacturer or through stores that deal in the particular printer you are looking at.

Discount ink cartridges are available online. All you have to do is type ink cartridges or printer cartridges into your search engine. Some sites offer amazing discounts. Again you are going to have to search for the deal that is best for you. Pay attention to the cartridge top when purchasing them. Check the sides of the box for a list of models the cartridge will work in.

There is a time line below that has some really interesting facts. This would make a great list of answers for a trivia game. I cannot imagine the hard work that created the ink jet printer cartridge, as we know it. It is easy to understand why cartridges are expensive.

1452 - Gutenberg used oil-based ink, moveable type, and an old winepress to make the first printing press. Martin Luther began the Protestant reformation making extensive use of the printing press.

1714 - The typewriter was born. Schematics that were done by Mills were discovered however, there is no proof that any typewriters were actually made.

1874 - Christopher Sholes, Samuel Soule, and Carlos Glidden made a keyboard that became known as the “qwerty” because of the first five keys on the top row of the keyboard.

1894 - Franz Wagner developed a typewriter that is very similar to the ones made today. He created a design that let the typists watch as they were typing. Previously, paper would go through a roller as you typed and you could not see what you typed until you were done.

1897 - Underwood (by John Underwood) was the prototypical typewriter of its day.

1939 - Charles Carlson developed electrography, which is the first dry writing technique developed in the United States.

1949 - Haloid Company began to commercially developed electrography for the first time.

1959 - Xerox 914 hit the market and forced other businesses to update their communication systems.

1969 - Xerox first introduced dry printing (laser printing) by Gary Starkweather.

1078 - Xerox put out the world’s first business laser printer the Xerox 9700. It copied documents at the speed of 120 ppm (pages per minute)

1979 - The IBM 3800 could print out 20,000 lines per minute. 1980’s - The use of toner cartridges became obsolete.

1984 - Hewlett-Packard released the first home-based desktop laser printer.

Headsets for phones are becoming more and more popular with the increased use of the telephone. Using the phone for long hours can be a real pain in the neck-literally. Complaints of neck and shoulder pain after extended phone use are increasing-phone headsets are an ideal solution for this problem.

Another major advantage? Headsets set your hands free and enable you to cook, type deed the baby-all while talking on the phone. The idea product for today’s multi-taskers

There are several other advantages, especially in the office. Apart from increasing the comfort level, phone headsets also help to lessen the external noise in the office and enable to concentrate better on the voice over the phone. Many employers, especially those in the contact centers, are thus increasingly considering investing in phone headsets for employees. An ideal phone headset should be comfortable, soft, durable, easy to use and also inexpensive. Adjustable headbands, accessible switches and controls, clear sound, good acoustical fit, adjustable listening and speaking volumes, compatibility with the phone are some of the things to be considered in a good phone headset.

There are several models available. These differ on the basis of mobility (wireless/ corded), the kind of ear piece (monaural/ binaural), the phone connection (Bluetooth, USB, 3.5mm/ Analog), the compatibility (to music), the kind of computer usage (VoIP, Computer Gaming), the range of bass/treble, the power of the speakers, noise-canceling ability etc. Most cell phones can accommodate the 2.5 mm plug that is generally offered with standard cellular headsets. However, some phones like Nokia, Ericsson and Nextel require special adapters for headsets.

The leading manufacturers of phone headsets are Plantronics, GN Netcom, Headsets.com, Sennheiser, Jabra, and Sony. The Internet is a good source for locating the ideal phone headset. There are several web sites that provide comprehensive information about the wide range available today. Manufacturers also provide online support specialists to help you select the best headset including discounts and warranties.

Whether you are crunching figures at a front office job or crouched over a blood and gore video game in some deep recess of your room, there is the right kind of screen available to suit your needs.

Monitors are one segment where you are truly spoilt for choice.

Be it a 15-inch, 17-inch or 19-inch CRT monitor* or a sleeker range of LCD screens*, there is a wide range to fit your budget. Hardware Software Articles: http://www.hardwaresoftwarearticles.com/archive/index.php/

*Size and resolution*

There are two aspects you must consider when selecting a monitor: physical size and resolution.

Screen size is the diagonal screen measurement, usually in inches. For instance, a computer monitor display might be 14 inches wide and 11 inches tall. This same screen has a diagonal measurement of 19 inches, which is the screen size.

Monitors also have an aspect ratio.

This is the ratio between the horizontal dimension and the vertical dimension (horizontal dimension divided by vertical dimension). Common monitor aspect ratios are 4:3 (1.3333) and 5:4 (1.25). Basics: http://www.hardwaresoftwarearticles.com/archive/index.php/f-2.html

A 4:3 aspect ratio means the picture is 4 units wide for every three units of height.

Wide screen monitors are easier on the eye (and much more expensive).

The higher the resolution, the greater the ability to render more detail. If you work with graphics or enjoy graphic-intensive games, you will need a monitor with higher resolution.

With most currently available models being flat screened, the difference is in the size and picture quality. A resolution of 1024 x 768 is a good one for most users.

*CRT monitors*

If you’ve decided to get a new CRT, make sure it has a sufficiently high refresh rate. This refers to how often the screen is redrawn per second. With low refresh rates you can get screen flicker and eyestrain. Virus: http://www.hardwaresoftwarearticles.com/archive/index.php/f-14.html

Aim for a rate of 75 Hz for a monitor up to 17 inches in size and 85 Hz for any larger monitor.

Another consideration for CRTs is dot pitch. The smaller the dot pitch, the sharper the image. Opt for a dot pitch of 0.26 mm or smaller.

CRTs function very well at multiple resolutions, can display detailed graphics and can be viewed comfortably from wider angles.

*LCD screens*

One of the primary disadvantages of LCDs when compared to CRTs is their limited viewing angle. When viewing a LCD straight on, it looks great. But the screen will appear washed-out if you move your head over to the side and look at it from a wider angle.

Also, LCDs are optimised to perform at a single resolution. Low-end LCDs have viewing angles of only 100 degrees, which won’t give everyone crowded round your desk a clear view.

For a standard 15-inch LCD, try to get a 140 degree viewing angle. Increase that by 20-40 degrees when shopping for an 18-inch LCD.

The brightness of LCD monitors is an important factor. LCD monitors have several backlights that provide illumination. The backlights in a LCD are good for 10,000 to 50,000 hours of operation. Ensure that the backlights come with at least a one-year warranty. Messenger: http://www.hardwaresoftwarearticles.com/archive/index.php/f-7.html

*Making a choice*

LCD screens generally cause lesser strain to eyes than CRT monitors.

CRTs have better graphics, but they tend to occupy five times as much space.

If you are a gaming freak, then a CRT is a better option as it is best for any graphic interface.

If you want the sleek look, an LCD is meant for you. It is widely used in banks and treasury and trading rooms.

Headsets or headphones are actually miniature speaker systems. They are stereo hearing systems that are wearable, thus providing mobility to the user. Traditional headsets were bulky and large with two speakers for both the ears encased in padded ovular ear cups. These ear cups were attached to a headband in the shape of an arch that went over the head. Each of these ear cups had a signal wire joined down together as a single wire, which was connected to the audio player/ radio through a headphone jack.

Today’s headphones are technological wonders-extremely lightweight with no irritating cords, almost negligible in appearance, with built in savoir-faire like noise canceling, sound quality, durability and comfort. These headsets are no longer meant for just listening to music or for professions like aviation or the military. Headsets today are making even activities like video conferencing, computer gaming, talking on the cell phone in noisy environments, and other activities extremely comfortable. Besides, these headsets also provide extreme flexibility to the user to do other things simultaneously like walking or even skating or skiing. Some headsets are so advanced that they cancel out external noise discriminately by eliminating only the undesirable noises. These are highly useful for recording studios and other musical environments.

Modern headsets also contain microphones for headsets that are meant for telephone or computer use. These are extremely useful in offices like contact centers where the main activity is to speak into a phone for hours. They enable hands-free operation and thus prevent stress on the neck, shoulder and hands.

There are different kinds of headsets available depending on the style (over-the head/ on-the-ear/in-the-ear/ behind-the-ear/ convertible), the options available (standard/voice tube/ noise canceling), the solution type (telephone use/mobile use/ headset adapter/ headset accessory), the mobility allowed (wireless/corded), the kind of ear piece (monaural/binaural), the kind of phone/computer connection to be used with the headset (Bluetooth, USB, 3.5mm/ Analog), the compatibility (to music), the kind of computer usage (VoIP, Computer Gaming), the range of bass/treble, the power of the speakers etc. Manufacturers also provide the support of online specialists to help you purchase the best headset, including discounts and warranties.

When buying a headset ask yourself the following: is it comfortable? Does it stay securely in place for long hours? Is the microphone flexible and unobtrusive? Is the cord long enough for easy movement? Are the volume and other controls easily accessible? Is the sound quality on both the lines clear?

The leading manufacturers of headsets are Plantronics, GN Netcom, Headsets.com, Sennheiser, Jabra, and Sony. Headsets are also very inexpensive, depending on the kind of model. A good pair of headphones costs around $10 though an extremely advanced model with all the works may be priced at $150-$200 or higher. The Internet is a good source for locating the ideal headset. There are several web sites that provide comprehensive information about the wide range of headsets available in the market today.

Take a good look at your notebook computer screen. Do you find some tiny dark spots? You could have dead pixels. One of the most expensive parts of your notebook computer is the LCD screen.

LCD’s are highly sensitive and any amount of pressure, touching or handling may damage it. As such, dead pixels aren’t an uncommon thing. Apparently, some degree of dead pixels is to be expected. Still if you have a lot of them, it would be classified as a defective screen. So, how do you determine if you have dead pixels?

Before we go there, make sure it’s not just dust. Clean your screen first. The best way to do that is to use a soft cotton cloth - no rags or paper towel as they can scratch your screen easily. Moisten the cloth with plain old water and wipe the screen gently.

Side note: I’ve also tried maintaining my screen dust free with a Swiffer Duster. These are inexpensive, very soft and they pick up the dirt not just re-distribute it. It has worked well. Of course, this will not take care of smudges or dried on dirt. So you’ll still have to use the cotton cloth and water combo sometimes.

Once you’ve cleaned it, you can run a quick check with a free software called Dead Pixel Buddy. It’s basically a very simple file that will rotate your screen through all the basic colors. This way you can tell if a pixel on your screen is not displaying properly. One tip, you might want to get a help of a friend. Two sets of eyes are better than one especially since pixels tend to be miniscule.

You can also do a low tech way by changing your desktop’s background color to black, white, red, green blue and yellow, checking the screen each time you change the colors. This is of course not fool proof especially if you have tons of icons on your desktop but it’s a good ‘backup’ check if you don’t have Internet access to download the file or whatever the case may be.

If you do find dead pixels, don’t panic yet, as mentioned earlier, a small amount of dead pixels could be inevitable but if you have a lot of them and your notebook computer is still under warranty, this may be a good time to call up the manufacturer and ask for assistance.
