Computer: Computer is an electronic programmable device that works according to instructions gives by User. Computers can understand only binary language i.e. 0,1. Units of computers are very important in order to bring proper control and co-ordination in system.

Computer helps us to save our data, information, our files, photos, videos etc. Computers are today mainly used for storing information, Browsing, Internet activities, Creating presentations, Communication, Exploring world using internet and doing complex calculations. It is to be said that, The computer has been passed through the 5 generations. Each generation of computer brought major changes to the world of computers.

Charles Babbage is a founder and known as father of Computers. He was mathematician, Mechanical engineer, philosopher and inventor. He is everything that first created a programmable computer. Because of this great invention, Today we are living a digital life.

Uses/Advantages of computers:

  • Storage: Computers can be used for storing data and using it while it is required.
  • Accuracy: Computers are very accurate. Hence, they have very high accuracy.
  • Efficiency: It is easy to use and understand the computer. We can do complex calculations, complex work on computer easily.
  • Communication: Computers can be also used for communicating through internet.
  • Internet: Once, we are connected to internet, then we can do exploration of the outer world.
  • Scientific calculations and predictions: At higher level, Computers are used for weather predictions, medical science, space research, AI development etc.
  • Employment: Software companies provides a lot of Jobs opportunities to people. Hence, Computers provides employment.
  • Speed: Computers have ability to perform the large task very rapidly.

Disadvantages of Computers:

  • Costly: Nowadays computers are costly. Due to which, poor people can't buy them.
  • High repairing cost: As computers are very costly. There repairing parts too are costly.
  • Overuse: Overuse of computers lead to various health diseases like problem in Back vertebral column, problems in neck and even Brain tumor may happen.
  • Effect on Children: Video games of computers affects the small child's most.

Types of Computers:

1) Mini computers  - Usually they are found in the Mini electronic devices like smartwatches, Calculators, Smartphone.

2) Tablet computers- Tablets which we see in our daily life; Eg: i-Pad, Samsung Tab....etc.

3) Digital computers - All the computers which we use today are digital computers. Digital computers are also referred as Personal Computer(PC).

4) Super computer  - This computers are generally used for research work, Meteorology, Servers,  Space research etc.

Generations of computer:

  • 1st generation of computer is beginning of the age of computers. In the first generation computers,
  • In the second generation of computers, The major change was using Transistors.
  • 3rd generation of computers used Integrated circuits for data processing.
  • Microprocessors were invented and used in 4th generation of computer.
  • Today, we are living in the 5th generation of computers. In this generation of computer, there is use of Nano processor.

Components of computer:

There are 5 basis components of computer, which helps computer system to run properly without any interruption. A computer system is designed in such a way that, every byte of information inputted should be processed properly, Such that user should get the required output.

i) Input Unit

- Input units reads the data provided from input device.

- This data in the form of binary code is sent to the computer unit.

- Computer unit processes the information and provides the necessary output to the user.

ii) Output unit

- It accepts the information provided by computer system in binary codes.

- But, we humans can't understand that language, So, Output unit converts the information from binary language to Humans language.

- Output unit includes Monitor, Sound system etc.

iii) Storage unit

- Storing the data and information in memory provided to output unit as a history.

- Processing the files required to output unit while using programs, applications and games from storage devices.

IV) Central processing unit (CPU)

- Arithmetic logical unit and Logical unit are the important components of this system.

- Architecture of computer is designed in this CPU, such that, only supported devices can perform the operations. Like CPU designed by IBM cannot be used to run Mac OS.

V) Arithmetic and Logic unit (ALU)

- ALU is an important component of CPU.

- ALU receives the data for processing from the temporary storage from the files called as "registers".

- All processing and computations are done by the ALU.
