What is a computer?

 

A computer is a programmable electronic device that can process, store, and retrieve data. It can perform a wide range of tasks, from simple calculations to complex computations. Computers are used in almost every aspect of our lives, from the devices we carry in our pockets to the supercomputers that power scientific research.

 

The basic components of a computer are:

 

1) Central processing unit (CPU): The “brain” of the computer, which performs calculations and executes instructions.

2) Storage device: Store data long-term, such as hard drives, solid-state drives, and optical discs.

3) Memory: Stores data and instructions for the CPU.

4) Input device: Allow users to interact with the computer, such as keyboards, mouse and touchscreens.

5) Output device: Display information to users, such as monitors, printers, and speakers.
