A computer keyboard allows an operator to give commands to the computer in a simple way by pressing keys. The keys on a keyboard are typically labeled with their input function, ranging from letters of the alphabet to numbers and symbols.
There is no one standard keyboard; all keyboard or computer manufacturers create their own. However, most keyboards are similar and feature the same basic functions. The most essential component to keyboards are the letter keys which allow an operator to write letters of the alphabet on programs on the computer. Keyboards can be found in nearly any language to match the settings on the computer. Aside from letters, numbers and basic navigation functions like arrow keys and the "enter" button are typically included on keyboards.
