The Clicking, Clacking Computer Keyboard
A keyboard is an arrangement of rectangular buttons or keys. The characters are printed or engraved on the keys. Almost all keyboard keys produce letters, numbers or signs. Other actions are available by simultaneously pressing more than one key. One such example is the Control-Alt-Delete combination. This command brings up a window on most versions of Microsoft Windows.
Different layouts for the keyboards are available depending on varied needs of people. These needs may vary depending on the language of people or the purpose for which the keyboard is being used. The best alternative layout for the keyboard is the Dvorak Simplified Keyboard. However, this layout is not in widespread use.
In recent times Wireless keyboards have become very popular. However, for the wireless keyboards to work, they need batteries. Not only that, they may pose security problem too. A wireless keyboard often includes a combination of transmitter and receiver unit that gets attached to the computer’s keyboard port. Radio frequency (RF) or infrared (IR) signals sent and received from the keyboard and the unit attached to the computer facilitates it to work as wireless keyboard. A wireless keyboard may use Bluetooth too. The latest addition to this type of keyboard is the KYE Systems SlimStar 820 Solargizer Unique keyboard and mouse set save energy by running on solar power.
There are different ways of connecting a computer keyboard. These include the standard AT (Din 5) connector, PS/2 and USB connection.
With technology improving by leaps and bounds, no wonder the keyboard has broken ground and has left the typewriter far behind.
