In this blog, we will cover some important topics related to Computers like What is Computer?, Computer Full form?, Types of Computer?, Advantages and disadvantages of a Computer? Etc.

Computers have made human life easier. Tasks that gets completed in days now can be done in minutes with the help of a computer. The discovery of the Computer is a blessing to the world.

Every task like storing data, long mathematical calculations, multi-tasking, etc. can be done easily with the help of a computer.

Computers are most commonly used in Hospitals, business organizations, banks, Schools, Research centres, Labs, Railways, Airports, etc.

As we know Computer is very important for us, but the full utilization of the computer is carried out with the help of internet. Internet is a global system that connects computers, Mobile phones, tablets, and more devices to send and receive data from one place to another.

Using the internet is as important as the computer. With the help of a computer, we can do any tasks in minutes however to send that data from one place to another, it requires the Internet.

Both Internet and a Computer together are very important to do multiple tasks. A Computer and the Internet have played a significant role in the world’s economy.

To get more accurate results, Computers are being used. Computers are widely used in the manufacturing industry.

The Task which humans used to do in days now can be done in minutes with the help of a Computer. There are chances of Human error, but Computer provides an accurate result.

What is a Computer?

The computer is derived from the word “Compute” which means to calculate. “A computer is an electronic device that is programmed to carry out Arithmetical and Logical operations automatically.”

A simple definition of the computer?

A computer is an electronic device that is used to carry fast calculations. A computer works based on instruction. It bases completion of any task on instructions we provide to a computer.

Let take an example – Suppose we want to calculate 15+27, We will give instruction to the computer to calculate 15+27 and it will deliver this instruction to a computer in a computer-readable form.

A computer can read binary code instruction that 0 and 1. Each instruction that delivered to the computer will be in binary code.

As per example, we have given instruction to the computer to calculate 15+27 and it will deliver the instruction to the computer automatically in binary codes. The computer will do a calculation in binary form and will deliver the result in a human-readable form that 15+27 = 42.

Keep in mind, every instruction that we will provide to a computer will convert into binary codes (0 and 1) automatically and the computer will do the task itself in binary codes but, it will deliver the results in human-readable form.

How is Computer Function or Work?

Computer work in three-phase Input, processing and Output.

Input- Input means installing any data on the computer. It can be any image, Video, etc. This is the first stage where we enter information to the computer.

Processing- This is an internal process where Computer processes the information that we inserted. Under this stage, the inserted data get processed.

Output- Output is the result that the computer will show us after processing data. It can store the output result for future use.

Let us learn with an example. You have inserted data 5+5 (we call this a command or input that we’ve provided to computer). The computer will take a few seconds to process that data and the time between input and output called processing.

Finally, a Computer will show the result 10 that is an Output.

Types of Computer

There are several types of computer, we will inspect a few on them.

1. Analog Computer
