The most commonly used way of using a computer is with a mouse. A standard mouse, shown left, has two buttons, for left and right clicking, and a scroll wheel. Other, more advanced types are available and can have features like macro buttons, adjustable wrist rests and adjustable sensitivity on the fly.

Keyboards allow users to directly input information into the computer. Word, Excel, Powerpoint etc all require a keyboard for the fastest, easiest possible use. QWERTY keyboards are wide spread, but other layouts, such as Dvorak are becoming more and more available.

Graphics tables are also on the rise, especially for graphic design. With a mouse, you can only be so precise, whereas with a graphics tablet you can have pinpoint accuracy.
