How a computer keyboard work

 

 

 

 Hi, I am Happy to see you today. we shall look at how keyboard works.

How does a computer keyboard work? Computer beginners should not be intimidated by the keyboard, as it is merely an instrument that can be quickly understood - and mastered.

The following is a brief explanation of the standard computer keyboard. It is not meant to be comprehensive but is designed to give first time keyboard users an overall peek at how the board is designed. Computer beginners should not be intimidated by the keyboard, as it is merely an instrument that can be quickly understood - and mastered.
To begin it should be noted that most keyboards have a two-colour combination. That is designed to assist in visual recognition for ease of operation. First time keyboard users are advised to study the colour ranges very carefully.
Experienced keyboard users will recognise that the main body of the keyboard is designed to conform to the standard "˜QWERTY' layout. That name is derived from the first five letters of the top row of the standard lettered keys.

The key to the extreme left of the top row is the "˜Esc' key. This key has numerous uses, all of which relate to "˜escaping' from a program or "˜situation'. The use of the key depends on the program being used and varies in individual programs. Its specific use in specific programs must be learned but it wise to keep it in mind and to use it when there is a need to escape from a problem.
On the top right hand side of the keyboard are three keys marked "˜Print Screen'. "˜Scroll Lock' and "˜Pause Break'. The uses of these three are obscure and are rarely used. For beginners they can be forgotten.
Along the top of the standard keyboard is a row of "˜F' keys. Like the "˜Esc' key each of these keys have certain functions that vary with different programs. For example, in "˜Word For Windows' the "˜F7' key opens up the "˜Spell Checker'. In the same program the "˜F12' key "˜saves' an open document. "˜F5' opens a function to let you "˜Go to' a location in your document. It almost universal in computer programs for the F1 key to be used to open a help menu.
In addition to individual functions the "˜F' keys are used frequently in conjunction with other keys. For example the "˜Shift' key, the "˜CTRL' (Control) key and the "˜ALT' key are frequently used either on their own or in conjunction with the lettered keys. In "˜Word for Windows' the "˜F7' key (used normally for the spell checker), when used with the "˜Shift' key, opens up a "˜Thesaurus' function. "˜Shift' and F3 when used together will toggle, or change, selected text from upper case to lower case and vice versa.
The keys along the top of the main keyboard have two uses. For example, the key with number "˜4' on it also has a dollar "˜$' sign on it. To type the dollar sign you hold down the "˜Shift' key and hit the number "˜4' key. The "˜Shift' key is used to type all of the symbols on the topside of each key.
The "˜CAPS' lock, when pressed down, makes every letter print as Upper Case. IF YOU PRESS THE CAPS LOCK KEY DOWN ALL THE LETTERS ARE PRINTED IN CAPITALS (UPPER CASE). Pressing down the "˜Caps Lock' a second time returns the key to its normal function. On the Internet typing in upper case is known as "˜shouting' and is frowned on in the computer world because it is more difficult to read than the standard use of UPPER and lower cases.
