The word alphanumeric means either letters or numbers. Every keyboard contains a set of keys known as the alphanumeric keys. Alphanumeric keys consist all the letters and numbers on the keyboard (i.e � A-Z and 0-9).� The alphanumeric keys are used for entering alphabets and numbers. The letter keys are set up the same way from keyboard to keyboard. On the top row, the letters Q,W,E, R, T and Y are lined up. Parts of the keyboard are arranged the same way on� virtually every keyboard. This common arrangement is called the QWERTY layout because the first six keys on the top row of letters are Q, W, E, R, T and Y. The number keys are located above the letters .Pressing the shift key and holding down a number will type whatever symbol is also on that number key. Symbols keys include @, %,&,# and number sins such as +,_,* etc.

Also the alphanumeric keys include the modifier keys such as Shift, Ctrl and Alt which are used in conjunction with the other keys.�
