Computer Components

A computer is an electronic device governed by software instructions that can accept, process, and produce results from data. Operating systems like Windows 7, Vista, and XP facilitate interaction between hardware and software. Data refers to raw, unprocessed items entered into the computer, while information is the useful output derived from processed data. Key components include input devices (like keyboards and mice), output devices (such as printers and monitors), and storage devices (USB drives and hard disks). Understanding these elements is crucial for effective computer use.
