An Operating System (OS) is a critical piece of software that acts as an interface between the hardware and the user. It manages the computer’s hardware resources and provides services for computer programs.
The processor, also known as the CPU (Central Processing Unit), is the brain of the computer. It processes instructions and manages all operations inside a computer.
A computer system is made up of two essential parts: hardware and software. Hardware refers to all the physical components of a computer. In this lesson, we’ll explore the basic building blocks of computer hardware.
Computers work through the interaction of hardware and software. Just like a human body (hardware) needs a brain (software) to think and act, a computer needs both components to function effectively.
Computers have become an essential part of modern life. From homes and schools to industries and research labs, computers are used everywhere. Their ability to store, process, and share information quickly and accurately gives them a powerful edge in every field.
Computers come in many forms and sizes. Depending on their purpose, power, and performance, they are classified into different types.
