Keyboards are essential peripherals for computers, primarily designed for inputting text and executing commands through key presses. They consist of a set of keys including alphabets, numbers, function keys, and sometimes additional multimedia keys to enhance user experience. Keyboards are widely used in various settings, from offices for data entry and correspondence to homes for personal computing tasks and gaming. The main characteristics of keyboards include their layout, the type of key switches used (such as mechanical or membrane), and their connectivity options (wired or wireless). Each type offers distinct tactile feedback and durability, catering to different user preferences and needs.
