Characteristics,Advantages & Disadvantages of Computer

Characteristics of Computer:

To understand why computers are such an important part of our lives, let us look at some of its characteristics −

·        Speed − Typically, a computer can carry out 3-4 million instructions per second.

·        Accuracy − Computers exhibit a very high degree of accuracy. Errors that may occur are usually due to inaccurate data, wrong instructions or bug in chips – all human errors.

·        Reliability − Computers can carry out same type of work repeatedly without throwing up errors due to tiredness or boredom, which are very common among humans.

·        Versatility − Computers can carry out a wide range of work from data entry and ticket booking to complex mathematical calculations and continuous astronomical observations. If you can input the necessary data with correct instructions, computer will do the processing.

·        Storage Capacity − Computers can store a very large amount of data at a fraction of cost of traditional storage of files. Also, data is safe from normal wear and tear associated with paper.

Advantages of Using Computer:

Now that we know the characteristics of computers, we can see the advantages that computers offer−

·        Computers can do the same task repetitively with same accuracy.

·        Computers do not get tired or bored.

·        Computers can take up routine tasks while releasing human resource for more intelligent functions.

Disadvantages of Using Computer:

Despite so many advantages, computers have some disadvantages of their own −

·        Computers have no intelligence; they follow the instructions blindly without considering the outcome.

Regular electric supply is necessary to make computers work, which could prove difficult everywhere especially in developing nations.
