What is Computer?

A computer is an electronic machine/device which takes input and gives output according to the instructions given to it. This is the simplest definition of a computer ever. the computer is an electronic machine/device which is used to accept data, process data into useful information, show the results and store it for later use.

A computer is a programmable electronic machine/device which takes input, process it into useful information, according to the instructions given to it, and also store it for later use.
Charles Babbage is the Father of Computer. 
Another computer simple definition is:

  • Electronic Machine/Device
  • Accept data
  • Process data into useful information
  • Show Results [Output]
  • Save Data/Information for later use.

Let's discuss the Parts of Computers:
  1. Input
  2. Output
  3. Processing
  4. Software
  5. Hard copy
  6. Soft copy
  7. Hardware
  8. Desktop Computers
  9. Servers
  10. Mini Computers
  11. Mainframes
  12. Super Computers

Input:

Anything given to the computer is called input. For example, you type something from your keyboard. This is called input because you give the computer an instruction to type that key.

Processing:

Processing is the process in which the data is converted into useful information, according to the instructions given to it. Instructions are usually called software or programs.

Software: 

A set of instructions given to the computer to solve a specific problem is called a program. A program or a set of programs is called software. A single software can not be a program but a single program
can be software.
  • System Software
  • Application Software
  • Package Software
  • Device Drivers
  • Customized Software
  • Operating System
  • Utility Driver

Output:

The processed data is called output. The output is usually shown on a computer screen. There are two types of outputs which are.

Hard Copy:

A hard copy is in the hard form, like a printed page or anything from a computer. Any printed form of electronic document on a page is called hard copy.

Soft Copy:

The output shown on the screen is called soft copy. Soft copies are the documents in the computer, which are saved and viewed electronically.

Hardware:

The physical parts of a computer are called hardware. Hardware is the components of a computer that we can see and touch. Keyboard, mouse, and monitor are examples of hardware.

  • Keyboard
  • Mouse
  • Monitor
  • System Unit
  • Trackball
  • Track pad
  • Printer
  • Scanner
  • CD ROM
  • DVD Rom
  • Hard Drive
  • Rams
  • Processor

The computer is divided into several categories due to its speed and size.

Desktop Computer:

A desktop computer is a type of computer, which is usually designed to fit on or under a desk. It is mostly designed for gaming. Mostly Home users use desktop computers for gaming or for their small works.

Server Computer:

A sever is a type of computer which can work as a center point in a network. It can share its hardware resources such as hardware, printer, scanner e.t.c and software like Operating  System. These computers are more faster than a personal computer and desktop computer. It can control access to a network.

Mini Computer:

Mini computers are the type of computer which can be carried from place to place. An example of mini computers is a Mac Book or Laptop.

Mainframes:

Mainframes are the fastest computers than desktop, servers, and personal computers. Mainframes can control thousands of computers at a time. The mainframes can solve billions of problems in a second. Mainframes are very big in size. It carries many places. The size of a mainframe computer depends on its speed and specifications.

Super Computers:

Super computers are the fastest computers ever, faster more than mainframes. Super computers can control million of computers at a time. The speed of the super computer is 1 quadrillion instructions in a second. Supercomputers are used in huge organizations.

These are the fundamentals of a computer and what is computer.

Fundamentals Of Computer

Computer fundamentals, do you know Computer is an electronic machine/device that takes input in the form of data or from the user and process that input into the useful information according to the instructions given to it.
So, let’s talk about computer a little bit briefly:

Electronic Device/Machine:

As I mentioned up a computer is an electronic device or machine. Do you really think that a computer is an electronic device or machine?
What is the difference between device and machine?

Computer as a Device:

A device is a tiny machine and a machine could be larger in size, if we takecomputer on behalf of the device then you are probably using your android phones. They are small handy devices which you can take from one place to another place and they are in types of computers.

Computer as a machine:

If we take computer as a machine then you are using your pc. Pc (Personal Computer) is an electrical machine you are using every day in your life.
So I think now your point is clear about it.

Takes Input:

As I mentioned here, that computer takes input.

Gives Output:

Then it gives output, output means results, I've told before in this article.
