Characteristics of computer science and technology-technicalcfg

 CHARACTERISTICS OF COMPUTERS

1. Automatic

An automatic Machine work by itself without human intervention. Computer are Automatic Machine because once started on a job, they carry out the job (Normally without any human assistance) unitl it is finished. However, computer being Machine cannot start themselves and cannot go out and find their own problems and solutions. Some of the other characteristics of computer ( such as speed and accuracy ) are because they are Automatic and work on a problem without anny human intervention

2. Speed

A computer is a very fast device. It can perform in few seconds, the amount of work that a human being can do in an  entire year-if he/she worked day and night and did nothing else. .

While taking about the speed of a computer we do not talk in terms of seconds or even milliseconds (10-3) but in terms of microseconds (10-6), nanosecond (10-9), and even picoseconds (10-12)

3. Accuracy

In addition to begin very fast , computer are very accurate. Accuracy of a computer is consistently High and the degree of its accuracy depends upon it's design. A computer perform every calculation with the same accuracy.

However , errors can occur in a computer. These errors are mainly due to human rather than than technological weakness. For example, errors may occur due to imprecise thinking by a programmer (a person who writes introduction for a computer to solve a particular problem) or or incorrect input data. We often refer to computer errors caused due to incorrect input data or unreliable programs as garbage-in-garbage-out (GIGO)

4. Diligence

Unlike human being a computer is free from monotony , tiredness and lack of concentration. It can continuously work for hours' without creating any errors and without grumbling. Hence, computer score over human being in doing routine type of jobs require great accuracy. If ten million calculation have to be performed, a computer will perform the last one with exactly the same accuracy and speed as the first one.

5. Versatility

Versatility  and in between, it may be helping an office secretary to trace an important letter in seconds.into it. In brief, a computer is capable of performing almost any task can be reduced to a finite series of logical setps.
