Computer Mouse and Keyboard Tips

Four Reasons to buy an Optical Mouse

Are you still using an old ball mouse to navigate your way through Windows Explorer or the Internet? Ball mice are old-fashioned and outdated! Keep in style and buy yourself an optical mouse. Everyone already has one these days.
If you do not happen to have one already, here are some great reasons to buy an optical mouse.
* Low Maintenance
An optical computer mouse no longer relies on balls to detect a cursor’s location on the computer monitor. The optical mouse emits a light emitting diode (LED) — usually colored red — that detects the device’ movements. When in movement, the optical mouse takes thousands of pictures of the flat surface on which it is placed. By measuring and comparing the small and minute distances the mouse travels when you move it about a flat surface, the optical mouse is able to tell how far to move your onscreen cursor.
Since it no longer uses a ball, the optical mouse is easier to maintain. You no longer need to clean up any balls when they get dirty. In addition, you can enjoy the benefits of smoother and continuous cursor movements. When the balls of mechanical mice get clogged with dirt and dust — and this happens often — cursor movement becomes irritatingly choppy.

* No More Mouse Pads
Optical mice can be used on any flat surface such as the top of your computer desk, a book or a bench. As such, they obviate the need for mouse pads. Ball mice, on the other hand, rely on mouse pads to detect and translate movement.
Make sure, however, that you place your optical mouse on an opaque surface. If you place it on top of a transparent surface, some of the LED will seep through the transparent surface. Consequently, your optical mouse will not be able to accurately record and process movements.

* Lightweight
Optical mice are lighter than ball mice. This makes them easier to maneuver. For those who work long hours in front of their computers, you will appreciate the lightweight build of an optical mouse. With an optical mouse, you will encounter less friction and resistance when moving your mouse about, and minimize hand and wrist strains.

* Eye-catching
One attribute that makes optical mice so appealing is their eye-catching colors and designs. The LED lights of optical mice alone are a treat. Usually sporting red LEDs, more modern optical mice can have green and blue LEDs. Others optical mice have transparent casings so their glow is evident in dimly lit areas. Some optical mice even cycle through many colors.
For appeal alone, an optical mouse is a great addition to your computer accessories!

Computer Desktop Tips

Four Types of Desktop Computers According to Architecture

Size and mobility are always an issue with desktop computers. These bulky PCs will always occupy a fair amount of space on your desk — which is why they are called desktops. There are, however, desktop computers that are smaller than others. Each has its pros and cons. According to architecture, desktop computers may be classified into four general types: small form factor computers, all-in-one computers, standard mid-sized computers, and tower computers.

* Small Form Factor (SFF) Computers
Small form factor computers are very portable desktops that range between a third and one-half the size of normal computer cases. Because of their small size, they can only accommodate a limited number of components. If you are contemplating on getting a small form factor, carefully consider which components you want to have. You may not be able to fit everything you want inside the small casing. The connectivity options of SFFs are also limited due to their size.
Most small form factors are barebone PCs that include a built-in motherboard, graphics card, and sound card. You can still attach a separate graphics card or sound card to your SFF at the cost of space.

* All-in-One Computers
Unlike the other computer types which need to be connected to an external monitor, all-in-one computers include an integrated LCD monitor. As such, these computers look like flat-screen televisions. The computer components are crammed and hidden behind the LCD screen. Because of limited space, all-in-one computer owners, like small form factor computer owners, have few upgrade and connectivity options. There are only so many components that can fit in a small box.
All-in-one computers are real space savers. Because you no longer need to connect your computer to an external monitor, you can clear up more space on your computer table and keep your desk neat and clutter-free.
* Standard Mid-Sized Computers
Standard computers are the most popular type of desktop computers at the moment. They are the regular-sized computers that you see everyday. Because space is not an issue, standard computers do not need any high-priced special components like SFFs and all-in-ones. Standard computer owners have a lot of room on which hardware to use and how many.

* Tower PCs
Tower PCs are designed for multimedia professionals and hardcore PC gamers. They are larger than regular PCs and can therefore accommodate a lot of extra hardware. Depending on your motherboard, you can plug in two graphics card, a separate sound card, a number of optical drives, and an equal number of hard disk drives into your tower PC. With a lot of hardware plugged in, tower PCs make very powerful machines.
Aside from their fast performance, tower PCs also minimize overheating issues. Because of their large size, more air can circulate within the casing. Many 3D gamers will even install fans to help keep components cool.
When scouting for a desktop PC, define your priorities. Do you want added mobility at the cost of performance, or more power but a bulky PC? If you are on a budget, a regular-sized PC is the best desktop to purchase.
