![]() ![]() The overall layout of the keys can vary depending on where in the world the keyboard will be used, since different countries have different character sets. Some keyboards are designed for a particular operating system (OS) such as Microsoft Windows, and may have additional function keys that are OS-specific. Laptop and netbook computers tend to have fewer keys and more restrictions on the way in which the keyboard is laid out than desktop computers, because the space available is limited. The number of keys can vary between 80 and 110, depending on the type of computer hardware the keyboard is designed for. This traditional layout was retained because it made the transition from using a typewriter to using the keyboard on a modern word processor or computer easier, and removed the need for any significant retraining of typists or secretarial staff (who effectively now became computer operators). Generally speaking, most of the keyboard layouts in use today are based on the traditional layout of mechanical and electronic typewriters (the typewriter was invented well over a hundred years ago), with the addition of a number of computer-specific control keys. The layout of the keyboard and the total number of keys provided can vary considerably. In many cases, additional symbols appear on a key to indicate a secondary function that can be invoked by pressing the key while another key (such as the ALT, CTRL or SHIFT key), or key combination (usually the ALT, CTRL or SHIFT keys in some combination), is held down. Every key on the keyboard carries a symbol that tells the user which character or control function it represents. The input takes the form of alpha-numeric characters, punctuation characters or commands, each of which may involve either a single keystroke or a combination of two or more keys being pressed at the same time. Each key sends a unique signal to the computer when pressed, so that the computer knows which keystroke has occurred. The keys themselves consist of electro-mechanical switches, the precise operation of which is dependent on the type of keyboard being used. Input takes place when the user presses the keys on the keyboard.
