Which component would you use primarily for input in most setups?

The keyboard is primarily used for input in most setups because it allows users to enter data and commands into a computer system. It provides a direct means of communication between the user and the computer, enabling tasks such as typing documents, programming, and navigating operating systems. Keyboards are specifically designed for input, featuring a layout that includes letters, numbers, and function keys, which makes them an essential tool for interacting with software applications and executing commands.

Other components, such as a monitor, printer, and speakers, serve different primary functions. Monitors display visual output from the computer, printers produce physical copies of documents, and speakers provide audio output. While these components can convey information to the user, they do not facilitate the input of data into the system like a keyboard does.
