The keyboard is the primary means of communication with the computer. Is the input device. Program and data is entered into the computer through a keyboard-like part to the typewriter standard. It contains alphabets (az or AZ) and numbers (0-9), (!,@,#,$,%,^,& private keys, etc.) and some control keys. Most keys are typematic that is, they repeat their function as long as they are being held down.
May be a keyboard encoder IC for small computers, or one slice is used for encryption. When you press the encryption key, which was revealed key is pressed and sends the binary code that may be ASCII, EBCDIC code, or HEX. In some computer systems, the keyboard sends the encryption just a symbol to refer to the examination, which was pressed on the key. And called for a computer keyboard offers translation program code to set the meaning of the survey which will give the desire of the binary code corresponding to the key pressure. It is well known for this approach, as two keys makes it possible to change the meaning of the various associated key on the keyboard.
