Characteristics of Computer
Speed, accuracy, diligence, storage capability and versatility are some of the key characteristics of a computer. A brief overview of these characteristics are—
1. Speed: The
computer can process data very fast, at the rate of millions of instructions
per second. Some calculations that would have taken hours and days to complete
otherwise, can be completed in a few seconds using the computer. For example,
calculation and generation of salary slips of thousands of employees of an
organization, weather forecasting that requires analysis of a large amount of
data related to temperature, pressure and humidity of various places,
etc.
2. Accuracy: Computer
provides a high degree of accuracy. For example, the computer can accurately
give the result of division of any two numbers up to 10 decimal places.
3. Diligence: When
used for a longer period of time, the computer does not get tired or fatigued.
It can perform long and complex calculations with the same speed and accuracy
from the start till the end.
4. Storage Capability: Large
volumes of data and information can be stored in the computer and also
retrieved whenever required. A limited amount of data can be stored,
temporarily, in the primary memory. Secondary storage devices like floppy disk
and compact disk can store a large amount of data permanently.
5. Versatility: Computer
is versatile in nature. It can perform different types of tasks with the same
ease. At one moment you can use the computer to prepare a letter document and
in the next moment you may play music or print a document.
Computers have several limitations too. Computer can only
perform tasks that it has been programmed to do. Computer cannot do any work
without instructions from the user. It executes instructions as specified by
the user and does not take its own decisions.
