Advantages of computer by noteubs nepal For neb exam
Computer is a versatile device. It can be
designed to do any kind of activity provided all data and instructions are made
available to it in digital form. The important advantage of computer are:
1. High Speed
2. Accuracy
3. Storage Capability
4. Diligence
5. Versatile
6. Reliable
7. Automatic
› High Speed
Modern computers have incredible speed of processing. It takes only few seconds for calculations that we take hours to complete.Computers makes it possible to receive, supply and process large volumes of data at very high speed.
Computer speed is measured in units of millisecond (one thousandth of a second), microsecond (one millionth of a second), nanosecond (one billionth of a second) , and picosecond (one trillionth of a second).
› Accuracy
Computer can ensure consistently very high degree of accuracy in computations. It processes data according to the sequence of instructions . Hence, if input data and procedures are correct, the output will be consistently accurate.
› Storage Capability
The Computer has an in-built memory where it can store a large amount of data. You can also store data in secondary storage devices such as floppies, which can be kept outside your computer and can be carried to other computers.
› Diligence
A computer is free from tiredness, lack of concentration, fatigue, etc. It can work for hours without creating any error. If millions of calculations are to be performed, a computer will perform every calculation with the same accuracy. Due to this capability it overpowers human being in routine type of work.

› Versatile
It means the capacity to perform completely different type of work. You may use your computer to prepare payroll slips. Next moment you may use it for inventory management or to prepare electric bills.
› Reliable
A computer is a reliable machine. Every Modern electronic computer's components have long lives. Now Computers are designed to make maintenance easy.
› Automatic
Computer is an automatic machine. It can ability to perform the given task automatically. Once a program is given to computer i.e. stored in computer memory, the program and instruction can control the program execution without human interaction.
Disadvantages
of computer
The main disadvantages of computers are
:
1. NULL IQ
2. Dependency
3. Environment
4. Feeling Less
› NULL IQ
Computer is a dumb machine and it cannot do any work without instruction from the user. It performs the instructions at tremendous speed and with accuracy. It is you to decide what you want to do and in what sequence. So a computer cannot take its own decision as you can.
› Dependency
It can do a task only if it can be expressed in a series of finite steps leading to the completion of the task. It does not have intuition. It cannot draw a conclusion without going through all intermediate steps.
› Environment
it cannot handle a situation where a finite number of steps generate an impossibly large number of computational operations. It cannot learn from experience. It will commit the same error repeatedly and cannot learn from experience. But changes are taking place in this areaas research progresses on artificial intelligence.
› Feeling Less
It does not have feelings or emotion, taste, knowledge and experience. Thus it does not get tired even after long hours of work. It does not distinguish between users.
