6. Speed: Preform numbers of task in a second. This is
called the speed of a computer.
Example of different units of speed are: millisecond,
microsecond, picosecond etc.
 Accuracy: Perform number of calculation in a fraction
of second correctly and accurately.(except GIGO)
Automatic: It carries out different tasks / work
automatically one instruction is given in the form of
computer program.
Features of Computer
System

7. Storage capacity: Store large number of data. The
quantity of data that a computer can store is the storage
capacity of that computer. Ex. KB, MB, GB, TB, etc.
 Reliable: It has a high degree as it carries out calculation
with high speed and accuracy.
 Diligent: Perform number of task without getting tired
unlike human beings
 Versatile: Used in variety of fields like education, health,
transportation, government etc. to do simple to complex
tasks.
