What is a keyboard

A keyboard is an input device that enables users to enter text, numbers, and symbols into computers or electronic devices. It is crucial for interacting with operating systems and applications.

History of Keyboards

The first keyboard, designed for typewriters, was invented by Christopher Latham Sholes in the 1870s. It introduced the QWERTY layout, which remains the most widely used keyboard layout today.

Types of Keyboards

Keyboards come in various types, each with unique features:

  • QWERTY keyboards: Common and efficient for English typing, though challenging for other languages.
  • Dvorak keyboards: Designed for improved typing efficiency, up to 30% faster than QWERTY.
  • Membrane keyboards: Thin and commonly used in laptops, less durable but more affordable.
  • Mechanical keyboards: Utilize individual mechanical switches for enhanced durability and tactile feedback.
  • Ergonomic keyboards: Designed for increased comfort, often split and adjustable to reduce wrist pain.

How Keyboards Work

Keyboards function by sending electrical signals to the computer upon key press. The computer interprets these signals to perform corresponding actions, such as typing a letter when the “A” key is pressed.

Uses of Keyboards

Keyboards are employed for various tasks, including:

  • Typing text and entering numbers.
  • Executing commands and navigating the operating system.
  • Playing games and interacting with applications.


Keyboards are indispensable input devices for computers and electronic devices, available in different types. Their versatility and efficiency make them an excellent choice for users seeking a reliable input method.
