What function does a monitor perform in a computer system?

A monitor primarily functions as an output device in a computer system, which means it receives signals from the computer's graphics card or integrated graphics and displays them visually on a screen. This allows users to see what is being processed and interacted with, including the operating system interface, applications, videos, and more. The process involves converting digital data from the computer into visual images, which can include text, graphics, and videos, allowing for effective human-computer interaction.

Monitors do not store data permanently, execute commands, or connect to the internet as their primary function. Instead, they are essential for presenting information in a user-friendly manner, enabling users to engage with software and perform tasks visually.
