Question

Name 4 characteristic of a computer

Answer 1

Answer:

1. Computer is a electronic device
2. It acceptes data from user and give desired output
3. It capable of doing very high level of calculation
4. It saves our time and energy for doing any work

Answer 2

Computer

Computers is an electronic device which is used for completing our work. It is being used by humans from so many years. And, Lots of changed had done in the computers in last 10 years. Because of computers, Life of Humans had changed totally.

Characteristics of computers:-

1. Computes make our work more easier. Because of which, we can do our hard work in less time and the complex calculations can be done rapidly with the help of computers
2. Computers are very easy to use. They are not so complicated to use, because of which computers become very important.
3. Storage: We can save our data and files in our computer. And, we can use that files when we have its need. Because of this file storage, Today we are able to see Videos, Photos and Music on our Mobile and computer.
4. Information: We can get the information of any kind of matter, Object, State and city with the help of computers. If computer is provided with the internet, then the computer can be used for various purposes.
5. If computer has internet connection, then, we can do online shopping, Payments, Booking, Near shops and many other things.

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. A computer system data transferring is very fast and efficient, so it takes a time less than a second to process and show the output.

i) Input Unit

- Input units reads the data provided from external environment.

- 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.

Uses of computers:

- Computers can be used for storing data and using it while it is required.

- Mathematical calculations can be done using computers.

- Computers can be also used for communicating through internet.

- Any kind of information can be achieved from the computers

- We can share our views with people using internet from computers.

- At higher level, Computers are used for weather predictions, medical science, space research, AI development and many more other things.

Types of computer:

i) Micro computer

ii) Macro computer

iii) Mini computer

iv) Mainframe computer

v) Supercomputer
