Keyboards are essential input devices used to interact with electronic systems such as computers, laptops, and quantum computers. They enable users to input text, commands, and symbols into these systems through a series of keys arranged in a specific layout. The design and functionality of keyboards can vary greatly depending on their intended use. For example, gaming keyboards may have additional buttons and customizable features for enhanced gameplay, while ergonomic keyboards are designed to reduce strain and improve comfort during extended typing sessions. Despite these variations, all keyboards share a common purpose: to facilitate communication between users and electronic devices.
