What are the capabilities of computer?

Answer 1

1. Speed: With a speed reaching up to fifty million operations per second, a computer can process data faster than any other machine designed to perform a similar task. That is, adding two numbers is considered as one operation.
2. Repetition: A computer can perform the same operation a million times in exactly the same way. The various operations are executed automatically by way of stored computer programs.
3. Accuracy: High-speed processing by a computer is accompanied by high-accuracy results. A computer can be considered 100% accurate. The electronic circuitry of computers is such that, when the machines are fed with correct instructions or data and when the incoming data is error-free, the accuracy of the output is relatively assured.
   1. Determining if a certain statement is true or false.
   2. Based on the result of the first step, choosing one or the other course of action out of the alternatives provided in the computer program.
4. Logical operations: The computer can make a decision based on alternative courses of action. The decisions of a computer are, however, dependent on the programs prepared for it by the programmer. A decision consists of two steps, namely:
5. Compact Storage: A computer has the ability to store large amounts of data in compact and easily retrievable form. It can store data at a very high speed.
6. Discipline: Discipline means that a computer can self-check and self-operate. A computer self-checks when it verifies the accuracy of its won work by means of a parity check. In a parity check, the computer counts the number of characters it has stored to make sure that there will be no loss of data during processing. In self-operation, a computer is capable of executing instructions on its own, without human intervention, once the program and the data re fed into the computer's memory.

Answer 2

1. Accuracy

A computer can process data quickly with 100% correctness if it is fed with right data output.

2. Self-checking

A computer verifies the correctness of its work to ensure that all data are accurate. It has its own built-in system that regulates the data flowing inside the computer.

3. Automatic

A computer can operate by itself if all data and instructions are fed properly into it. T can execute instructions without human intervention.

4. Speed

A computer can process and calculate large amount of data and problems at a very fast rate. It can outdo a man in adding two numbers by hundredths of a second.

5. Repetitiveness

A computer can do a job or a task as many times as you want it to be done. It never complains or gets bored like a human being.

6. Store and Recall Information

A computer can keep info for later use. It uses either a diskette or the memory that can store millions of characters. A computer can also retrieve or get information from the disk or the memory.

7. Wide Range of Application

Computers are in the fields of business, communication, education, and entertainment. They are an essential tool of everyday living from simple household task to the most complicated activities
