A keyboard contains numerous mechanical switches or push- buttons called" keys". When one of these is pushed, an electrical circuit is about to close, and the keyboard is used to send a signal to the computer that tells it what letter, number, or symbol it would like to be displayed on the screen. Numerous keyboards connect to the computer through a string with a PS/ 2 or USB (Universal Periodical Machine) connector. Laptops use internal connectors. Anyhow of which type of connector is used, the string must carry power to the keyboard, and it must carry signals from the keyboard back to the computer.
A computer keyboard is considered an input device because it only sends data to a computer and doesn't admit any information from it. As you type on the keyboard, you are inputting information into the computer. Share your blogs at business.glimpse.info@gmail.com for the topic Gadgets Write For Us
