Software, on the other hand, refers to the non-physical instructions and programs that tell the computer hardware what to do. Software is intangible and cannot be touched or seen. Examples of software include operating systems, word processors, web browsers, and video editing programs. Software is designed to perform specific tasks and provides instructions to the hardware on how to accomplish them. Without software, the hardware of a computer would be useless.

What is called hardware?
Hardware refers to the physical components of a computer system that can be touched, seen and interacted with. This includes devices such as the central processing unit (CPU), memory, hard drive, monitor, keyboard, mouse, printer, and other peripheral devices. Hardware components work together to enable the computer to perform various tasks and execute software programs

The input devices, such as the keyboard and mouse, allow users to interact with the computer and provide it with data and instructions. This input is then processed by the central processing unit (CPU), which performs calculations, executes programs, and manages the flow of data within the computer.
The CPU communicates with memory, which temporarily stores data and instructions that the CPU needs to access quickly. This memory is typically volatile, meaning that it loses its contents when the computer is turned off.
Finally, the output devices, such as the monitor and printer, allow the computer to communicate with the user by displaying information or producing physical output.
