Have you ever seen a TV like machine with a board kept in front of it on a table at your home or on a desk in your school? That machine is called a “computer”. A picture of the computer is shown below.

Definition of a Computer
A Computer is an electronic machine that is designed for storing and processing the information and it performs several arithmetic and logical operations according to the set of predefined instructions.
Parts of a Computer
Humans have body parts like hands, legs and fingers… Similarly a computer also has some parts.
A computer having parts
Let’s see the basic parts that any computer can possess.
A computer monitor
A Black colored computer keyboard
A Computer Mouse
CPU: A CPU, also called the central processing unit, looks like a black cuboid box. It is Brain of the computer because it stores the information, takes input and processes to give the desired output.

Fundamental Functions of a Computer
Why do we need a computer? A computer takes input from the user and processes it to give the desired output. To understand the concept clearly, let’s understand it with a simple real life example.
For example, we need a mango juice, for that we want mangoes and sugar and a juicer. After adding the mango pulp into the juicer, we get a pure mango juice. So, here we are giving mango pieces as inputs and the juicer is a processing unit and the mango juice we got is the output.
A real life example of Input - Process - Output
Similarly, you can give inputs to the computer, the computer processes the inputs and gives the output.
Let’s say you want to print a letter, you type the letter with the help of a keyboard, the CPU makes it ready to print and the printer prints it. Here the keyboard is the input device and the printer is the output device.
Function of a computer
Let’s see the different types of input and output devices in a computer.
Keyboard, Mouse, Microphone(Mic), Camera, Joystick and scanner are some Input devices of a computer.
These devices are designed to take inputs from the user. These input devices are connected to the computer.
Monitor screen, Printer, Speakers, Headphones, Projector are the output devices. These are also connected to the computer with the help of a wire or a wireless connection. These devices show/give the required information.

You can do many things with the help of computers like painting a picture, writing letters and Emails, book travel tickets and rooms, order food online and what not!
The term "computer basics" refers to the fundamental knowledge required to operate and interact with a computer. This includes everything from knowing the different parts of the computer to understanding how to use those parts to achieve a specific output. Computer fundamentals are the foundation of computer literacy.
