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