If we think technically then, Computer is a programmable machine. It can execute the instructions of a programmed list and at the same time can respond to the new instructions which are given to them.
But in today’s time this term ‘Computer’ is used for desktop and Laptops are used to represent the computers which are used by most of the people nowadays. When we refer to a desktop model, the term “computer” technically refers only to the computer itself – not its monitor,The keyboard, and the mouse that are connected with it.
Despite this, the summation of all these devices is called computer and is also understood. If I tell you in full technical language, then the box which holds the sytem is called “system unit”.
Some of the major parts of a personal PC include the motherboard, CPU, memory (or RAM), hard drive, video card . Although personal computers are the most common type of computer in today’s time, along with it, many different types of computers are also found.
For example, a “minicomputer” is a very powerful machine that supports many users simultaneously. “The mainframe ” is much larger, a high-powered computer that performs billions of calculations from multiple sources at the same time. In the end, a “super computers” is a machine that processes billions of instructions a second and is used to perform extremely complex calculations.
