Keyboard

Keyboard is the main input device of a computer. Without a keyboard it is impossible to imagine working on a computer. Keyboard is a lot similar to a typewriter but has added keys that enhance the features and capabilities of a user working on a computer.

The today's keyboards consist of about 101 to 106 keys. The layouts are basically the same with the odd key situated differently. It is generally connected to the PS2 or the USB ports of the motherboard. There are many types of keyboards available these days, but one should always buy that is suitable and comfortable. Some are springy others have mushy feeling.

Yes, you get a keyboard when you buy a computer, but, it is not necessary that you have to use it. Keyboards are an inexpensive item that can be replaced easily. But, it doesn't mean that all keyboards are inexpensive as today's markets have very hi-tech keyboards.

Once you've found a keyboard that you find it comfortable, one of your main concerns should be proper typing form. Repetitive stress injuries are a concern and poor posture can also result in back and neck pain. Sit up straight and find yourself a chair that supports the natural curve in your back. It should be adjusted to your keyboard so that you don't have to lean forward or hunch to type.

Your shoulders should be relaxed with your forearms and wrists fairly level, fingers slightly curved. Wrist pads are made for you to rest your wrists on while taking short breaks, your wrists shouldn't be on them while you type. Don't sit and type constantly, try to take a few breaks every now and then and have a stretch.
