What is a keyboard? A keyboard is an input device used to input data into a computer or other electronic devices. It consists of keys or buttons that, when pressed, produce characters or perform functions such as typing, controlling media, or navigating through a user interface.
The keyboard is one of the most important and most used peripherals in computing. It is used in homes, offices, schools, and other places where people need to input data into a computer. The keyboard is used for typing letters, numbers, and symbols, as well as for navigating through the computer's operating system and applications.
Layout
The layout of a keyboard is standardized, and most modern keyboards have a similar layout. The standard keyboard layout includes alphanumeric keys, function keys, navigation keys, and other keys specific to the operating system. The alphanumeric keys are used for typing letters, numbers, and symbols, while the function keys are used to perform specific tasks, such as saving a document or printing a page. The navigation keys are used for moving the cursor and scrolling through documents.
History
The first keyboard was introduced in the late 19th century and was designed for use with typewriters. It was similar to the layout of today's standard keyboard, and it allowed users to type characters and perform basic functions. Over time, the keyboard evolved and became an integral part of computing.
Improvements
One of the main improvements to the keyboard was the introduction of the QWERTY layout. This layout was designed to reduce the likelihood of jams in early typewriters, and it became the standard layout for keyboards. Today, the QWERTY layout is still used in most standard keyboards.
Another improvement to the keyboard was the introduction of the function keys. These keys allowed users to perform specific tasks, such as saving a document or printing a page. They were initially located at the top of the keyboard, but over time, they have been relocated to the left and right sides of the keyboard to make them more accessible.
The introduction of the computer mouse also had a major impact on the keyboard. The mouse allowed users to navigate through the computer's user interface and perform tasks with greater ease. This, in turn, reduced the need for the keyboard to perform navigation functions. As a result, the keyboard was able to focus more on its primary function of inputting data.
Types
In recent years, there have been many new developments in keyboard technology. One of the most notable is the introduction of the mechanical keyboard. This type of keyboard uses mechanical switches to register keystrokes, and it offers a more tactile and satisfying typing experience than traditional rubber dome keyboards. Mechanical keyboards are popular among gamers, writers, and other users who type for extended periods of time.
Another development in keyboard technology is the introduction of wireless keyboards. These keyboards communicate with the computer using wireless technology, such as Bluetooth or RF, and they eliminate the need for a cable between the keyboard and the computer. Wireless keyboards offer greater mobility and freedom of movement, making them ideal for use with laptops and other portable devices.
Another type of keyboard is the ergonomic keyboard. This type of keyboard is designed to reduce the risk of repetitive strain injuries, such as carpal tunnel syndrome, by placing the hands in a more natural position. Ergonomic keyboards come in various shapes and sizes, and they are often split into two separate sections to reduce the strain on the wrists.
Finally, there is the multimedia keyboard, which includes additional keys for controlling media and other functions. These keys allow users to play, pause, skip, and control the volume of music and videos, as well as to perform other tasks. Some multimedia keyboards also include programmable keys that can be customized to perform specific functions.
