Which term refers to an understanding of how a computer functions leading to comfort in its use?

The term that refers to an understanding of how a computer functions and promotes comfort in its use is computer literacy. This concept encompasses not just the basic ability to operate a computer, but also an understanding of fundamental principles related to computer systems, software applications, and the internet. Being computer literate enables individuals to effectively use technology to perform tasks, solve problems, and access information in a digital environment, thereby enhancing their productivity and confidence in utilizing various technological tools.
