In this Blog Post we will discuss all above mentioned points one by one in a very simple way. The ABCs of computing means everyone can understand easily the computer basics.
1. Origin of word Computer:
The basic reason of computer’s invention was the mathematical calculations. In early days the computer used for calculating values. So the word computer derived from a “Latin” word “compute” which means “to calculate”.
2. Definition:
What is Computer?
Computer is an electronic machine which takes input from user, process it, gives output and store it for later use.
A computer can accept instructions as input from user and perform operations on it and gives information as output. It stores information for later usage.
3. Why is computer important in human life?
In early days manual working was too much time consuming and human spent large amount of time in solving problems. The invention and advancement in computer take over the manual working system and now computers are solving very complex and large amount of problems in a tiny time frame as compared to human. Due to its fastest working speed and accuracy in results computer given preferred. To utilize computer in daily life everyone should must knowledge about The ABCs of Computing.
4. Characteristics of Computer
Let we discuss some characteristic of computer which makes prominent the reasons why computer is important?. The ABCs of Computing has the following characteristics.
- Speed: Computer is a speedy machine. A problem that a man can solve in hours, days, can be solved by computer in micro seconds. Most of computers perform billions of operations in one second.
- Accuracy: Computer’s work is accurate; it does not make mistakes. The errors may occur due wrong input, wrong instructions or bugs in its chip. All the errors are due to human. Computer performs action accurately and computers can do the same task repetitively with same accuracy without any break.
- Reliability: Computer is too much reliable because it does not produce wrong results and never tired if we use it continuously. So it is accurate and tireless machine.
- Versatility: Computer is a versatile machine which can perform different kind of tasks with same efficiency and accuracy. If we perform a 100 tasks for hundred times, it will work with same efficiency and accuracy as it performs first time.
- Adaptability: Computer has ability to work and control each & every electronic device. You can plug camera, motors, fax and many other machines with it to get required result.
- Storage Capacity: Computer is used due to its huge storage capacity. Data that you can place in 200 Almirah can be stored in a computer on its small hard disk sized 3 to 5 inches. Hard disks of computer can store huge amount of data, which can be accessed any time.
