BELOW ARE THE PARTS AND FUNCTIONS OF THE COMPUTER KEYBOARD THAT ARE COMMONLY USED.
These parts of the computer work as the main part because their primary function is to enter commands of the computer from your hands and fingers. By pressing it accordingly on the computer keyboard. So, meaning you need to know the different parts of this keyboard.
Take note that the computer keyboard is commonly designed as QWERTY that you'll see at the left home keys or side of the alphanumeric keys located at the first line of keys of the letters. Even that is PS/2 or USB type keyboard. You can watch also the whole video in my Facebook Page.
1. MAJOR FUNCTIONS OF THE KEYBOARDS- these are the 5 major functions, these are the Function keys (All F keys), Alphanumeric keys, 9 Special keys, Cursor keys (Arrow), and the numeric keypad.
2. COMPOSITION OF ALPHANUMERIC CHARACTER- is the biggest part of the PC keyboard, it is the letters from A-Z, numeric numbers from 0-9, characters are symbols and punctuation, and the special keys.
3. SYMBOLS, PUNCTUATION, AND SPECIAL KEYS BELONG TO ALPHANUMERIC CHARACTER- these are the symbols and punctuation both located in upper and lower cases. And the special keys position the left bottom and the right side of this part.
THESE ARE BOTH SYMBOLS AND PUNCTUATION:
