Characteristics of Computer
The characteristics of computer are high speed of operation,accuracy, reliability, capabilities, limitations, flexibility, and economy coupled with efficiency in storing and processing data. Computer have capabilities and also limitations to do work.Speed
Internal
processes of computer operate at the speed of light, limited only by
the program that control these processes and the quantum of data under
the speed with which computers perform is wat beyond human
capabilities. It can carry out instructions at a very high speed
obediently, uncritically and without exhibiting any emotions .The speed
of computer is calculated in milliseconds(10-3) .The unit of speed are in microseconds(10-6),nanoseconds(10-9) ,and even picosecond(10-12) .
Accuracy
The
Accuracy of a computer is consistently high. Error can occur,but these
are almost always due to human error rather than technological
weaknesses. Imprecise thinking by the programmer, inaccurate data or
poorly designed systems is the origin of error.Computer error arising
due to incorrect data input or unreliable program are often referred to
as GIGO(garbage- in garbage -out)
Dilligence
Unlike
human beings,a computer does not suffer from limitations associated
with living beings like tiredness and lack of concentration and hence
can work for hours at a stretch without error arising from the
above(non-existent) faults. As a result, computers score over human
beings in performing rountine tasks that require a high degree of
accuracy.This characteristics is especially useful for those jobs where
same tasks is done again and again. It can perform long and complex
calculations with same speed and accuracy from the start till the end.
if a million calculations need to be performed,a computer will perform
the millionth calculation with exactly the same accuracy and speed as
the first one.
Versatility
Computer
are capable of performing any task. Multi-processing features of
computer makes it quiet versatile in nature. Provided the task can be
reduced to a series of logical steps.For example a task such as
preparing a payroll can be broken down into a logical sequence of
operations and is therefore ideal for computerised processing
