Define the term computer. Write down the major characteristics.
An electronic device which accepts raw data from users and processes it to give meaningful result and store the important data for future use is called Computer.
The major characteristics of the
computer are as follows:
a) Speed:
- Computers can perform billions of calculations within fractions of a second.
Actually most modern computers perform a task in a Picoseconds. The processing
speed of computer is measured in the unit of Hertz (Hz).
b)
Accuracy: - Accuracy means
correctness. Computer works on GIGO (Garbage input and garbage output)
principal. It means the computer provides the correct result if the inputs are
correct.
c) Diligence:
- The computers never feel tired and bored to do a same task repeatedly. The
computer can perform the same task with same speed and accuracy for a long time
if it is provided the suitable environment and correct instruction.
d)
Reliability: Computers are
designed in such a way that their every individual part has a very high life
span.
e) Versatile:
- Modern computer perform various types of job efficiently. Same computer can
be used in bank, office, school, cyber etc for doing different types of tasks.
Some computer plays movies and music in it, other uses it as a server computer
etc.
f) Automatic: Computer is an automatic
machine because a task has started; a computer can proceed its own till its
completion. A computer can be programmed to perform a number of tasks with the
help of program.
g)
Storage Capacity: - A
computer has high storage capacity. It has data storage area called memory. Any
data stored in the memory can be retrieved at any time and at very speed.
