The keyboard is the most commonly used and the most important input device. Through the keyboard, English letters, numbers, punctuation marks, etc. can be input into the computer, so as to issue commands and input data to the computer.
The keyboards in the PC XT/AT era were dominated by 83 keys and lasted for a long time, but have been eliminated with the popularity of the Windows system in recent years. Instead, 101-key and 104-key keyboards occupy the mainstream position in the market. Of course, there have been 102-key and 103-key keyboards, but due to poor promotion, they are only short-lived. In the past six months, the 104-key keyboard has been followed by the emerging multimedia keyboard. It has added a lot of commonly used shortcut keys or volume adjustment devices on the basis of the traditional keyboard, which further simplifies the PC operation. For sending and receiving emails, opening browser software , start the multimedia player, etc. all only need to press a special button, and at the same time, the appearance has also been greatly improved, emphasizing the personalization of the keyboard. At first, this type of keyboard was mostly used in brand machines. Brand machines such as HP and Lenovo were the first to adopt this type of keyboard, which was widely praised and was once regarded as a feature of brand machines. With the passage of time, there are gradually independent products with various shortcut functions sold separately on the market, and with dedicated drivers and setting software, which can also realize personalized operations on compatible machines.
