WEEK 2
Topic Importance of Computer as a Tool For Processing Data Computer is the most powerful machine in today’s world. It has become the need in everyone’s life. A computer can perform task very quickly and accurately. Computer has its own features and characteristics.
Some of the important characteristics of computer as a tool for processing are described below:
Speed
The data processed using computer system is done at a very fast rate which other machine cannot.Speed of computer maybe defined as the time taken by a computer to perform a task. It takes only a few seconds for the calculations that we take hours to solve. Its speed is measured in term of MHZ (Mega Hertz).
Accuracy
The computers are the accurate machine that can perform large number of tasks without errors, but if we feed wrong data to the computer it returns the same wrong information called GIGO (Garbage In Garbage Out).
Reliability: Computers are the most reliable machine that has ever Exist in human history therefore any information obtained from computer processed data is highly reliable.
Diligence
The capacity of computer of performing repetitive task without getting tired is called diligence. A computer is free from tiredness, lack of concentration, fatigue etc therefore it can work for hours without creating any errors.
Versatility
The capacity of computer of performing more than one task at the same time is called versatility of computer. Versatility means the capacity to perform different types of work completely.
Storage
Computer has mass storage section where we can store large volume of date for future use. Such data are easily accessible when needed. Magnetic disk, magnetic tape and optical disk are used as mass storage devices
Automatic
Computer is an automatic machine which works without the intervention of the user. The user is required to give the data and utilize the result but the process is automatic.
