What is introduction to computer?
Introduction to Computer:
Introduction to Computer is it has become necessary for every individual in this era. To introduce the computer let me tell you that the word computer is derived from a Greek word “compute” and it means to calculate. It is an electronic device, with a software program.
It has some input devices like mouse/keyboard and it gives output through output devices like color monitor, printer etc. it comes in different sizes, some are very are very big in size and other are small in size. As there are different sizes in computers they also have different processing speed some are very fast computers and some have normal speed. Almost every individual is globally using computer.
Uses of computer
Some common uses of computer are :
- It is used to process business data
- It is used to maintain accounts (in banks also).
- It is used to maintain stocks like it is used in departmental stores.
- It is used to store information about any person, place or thing.
- It can be used as a video player.
- it can permanently store data in it.
- It can be used to send mails to our friend, family members, and to our relatives.
- It is used to check the weather forecast.
- It is very helpful to do studies.
- It can be used to play games.

Characteristics of Computer are:
- Speed
- Accuracy
- Data performance
- Reliability
- Storage
- Automation
- Versatile
- Communication
- Diligence
- Intelligence
Explanations of the characteristic.
- Speed: It has a very high processing speed it can execute billions of instructions which you gave it in few seconds. It’s speed is in MHz (Mega Hertz) or GHz (Gega Hertz).
- Accuracy : The fast working computer doesn’t means that it will provide falls information, It gives accurate results of the given inputs if the given inputs are correct.
- Data processing : It is the most important function of a computer. Process of processing data and converting it in to useful information is known as data processing. Computer runs many operations under this process. The most important functions are:-
- Arithmetic operations: like DAMS
- Logical operations: like analyzing data.
- Reliability: As it has almost no failure rate in today’s world. This ability of computer makes it to much reliable that it can do perform multiple tasks at once without giving any error with accurate results. It is observed that there is very less chance of the computers and communication networks to crash which tell us that how much they are reliable.
- Storage: A computee is having two types of memories (storage s).
Primary and secondary
- Primary storage is temporary memory as it stores data for processing only.
- Secondary memory is the permanent memory of a computer which can store large amount of data in it, for a long time.
- Automation: It means that it is smart enough to do tasks by its self, Once data and commands is given to it it can automatically perform operations on that given data with accurate results. It can control connected the devices automatically.
- Versatile: The word means flexible, which means it is not fixed to perform a same task it can perform tasks of different nature. You can play game, you can send email, you can do studies etc. So your computer is versatile to do anything by your command.
- Communication: Computers can communicate with each and other through network, which helps us to share information. In present era computers are very useful to send and receive messages and data through network world wide.
- Diligence: A computer can do working for many hours without doing any rest, and it dose not give any sort of error even after working for a long time.
- Intelligence: Computer is not intelligent by itself. It just follows the commands of the user who is a human being not a computer.
