A laptop keyboard is a peripheral input tool modeled after the typewriter keyboard that uses buttons or keys to electronically input data. Since the 1970s, keyboards have been the primary way for users to enter information into computer systems, along with computer mice in the 1980s. Keyboard keys typically have characters printed on them and pressing a key corresponds to a single character, though some symbols require pressing multiple keys at once or in sequence. In addition to character keys, other keys trigger computer commands. Modern computers interpret key presses through software rather than hardware.

1. A laptop keyboard is a peripheral input tool modeled after the typewriter keyboard which takes
advantage of an association of buttons or keys to act as mechanical levers or electronic switches.
Replacing early punched cards and paper tape technology, interplay through teleprinter-fashion
keyboards had been the main enter technique for computer systems since the Nineteen Seventies,
supplemented through the pc mouse for the reason that 1980s. Keyboard keys (buttons) generally
have a set of characters engraved or printed on them, and each press of a key commonly
corresponds to a unmarried written image. However, generating some symbols might also
require urgent and protecting several keys simultaneously or in series. While most keys produce
characters (letters, numbers, or symbols), different keys (inclusive of the escape key) can set off
the pc to execute device commands. In a modern-day laptop, the interpretation of key presses is
normally left to the software program: the records sent to the pc, the experiment code, tells it
most effective which physical key (or keys) was pressed or released.
