History of Computer Keyboard
A computer keyboard has a long history. It is made to help people type faster and give instructions to computers. The first keyboards were inspired by typewriters. The typewriter was invented by Christopher Latham Sholes in 1868. Then, keyboards started to change for computers in the 20th century.
Early Typewriters (1868–1940s)
The first typewriter by Sholes was made in 1868. It had letters and numbers arranged to prevent jamming. This layout served as the basis for modern keyboards. People used typewriters to write documents before computers were invented.
First Computer Keyboards (1940s–1970s)
The first computer keyboards appeared in the 1940s. They were used with early computers, such as the ENIAC. These keyboards were very big and heavy. They are not like today’s keyboards; they were used to send instructions to the computer.
Modern Keyboards (1980s–Present)
In the 1980s, keyboards became smaller and easier to use. The QWERTY layout became standard. Then new types appeared, such as mechanical, membrane, and wireless keyboards. Modern keyboards are fast, light, and very helpful for typing and controlling computers.
How a Keyboard Works
A keyboard is a tool that sends instructions to a computer. When a person presses a key, the keyboard sends a signal to the computer indicating which key was pressed.
