Your keyboard is essential to you "communicating" with your computer. Without it, even the best computer is just another expensive piece of electronic equipment!
The computer keyboard is a "descendent" of the typewriter, and the original models had only 84 keys. However, the keyboard has "evolved" to include extra function keys (101 or 104 are the most popular), which are preprogrammed for specific uses. The function keys can work independently, or can be used simultaneously with other keys. (We ALL know what ctrl-alt-delete does - right?) Many of these added keys assist the user with editing and searching more efficiently, and are called "shortcuts" or "hotkeys."
Computer keyboard options are many and varied. Below are some options you should consider before making your purchase.
• PS2 connection vs. USB2.0 connection - most keyboards use the PS2 connection; although more recent keyboards now offer a USB2.0 connection. There is really no difference, although opting for the original PS2 version "frees up" the USB2.0 slot for other devices (i.e. digital camera or MP3 player);
• "Split" keyboard - ideal for those just learning how to type, this keyboard is literally "split", so the keys are evenly divided on each side of the keyboard;
• Ergonomic keyboard - these keyboards come with a contoured shape, designed to allow the user's hands to remain in a "natural position" while typing, which, in turn, helps reduce the risk of repetitive stress injuries to the wrist;
• Multimedia keyboard - frequent multimedia users may consider this keyboard, which offers extra shortcut keys providing one-step control of devices, including media players and/or video playback;
• Wireless keyboard - although somewhat more costly, this may be a consideration if you tend to "be on the move" while using your computer. The wireless keyboard enables "typing" on the computer from across the room;
• Gaming keyboard - if you are a gamer, it is best to get a gaming keyboard. Look for in-game control and hotkey programmability. Some keyboards offer up to 18 programmable hotkeys as well as an LCD display, providing a clearer view of the game information;
• Colored, backlit and waterproof keyboards - for the ultimate in customization!
• Standard keyboards - generally speaking, the keyboard that comes "standard" with your computer purchase will work well for all the basics - word processing, internet searching, etc. Standard keyboards also usually have an independent number pad should your needs entail significant "number crunching."
Finally, relax! No need to get overly stressed about your computer keyboard purchase! Remember that your keyboard will "die" long before your computer does, simply because it endures more direct, daily "physical" contact - even more than your computer mouse! Fortunately, in terms of computer accessories, keyboards are generally very affordable!
