Most laptop computers have an integrated mechanical keyboard, and desktop computers are usually operated primarily using a keyboard and mouse. Devices such as smartphones and tablets mean that interfaces such as virtual keyboards and voice recognition are becoming more popular as text entry systems.
As the key is pressed, a switch closes and current flows into a small chip in the keyboard. Each key on the keyboard has an associated number, called a scan code. This is useful when it comes to keyboards that have different layouts and/or symbols. This scan code is sent into the computer as a binary number.
