7. The speed with which computers can process
large quantities of data/ Information, the size
of input so also the output is quite large. The
size of information to be stored further
increases due to graphic applications. All this
information is to be stored in auxiliary memory
i.e Hard Disk fitted inside the computer. Hard
Disks now days have a storage capacity as
large as 4 GB. The size of internal primary
memory (RAM) has also been increases a lot to
about 64 MB

9. Computers are capable of performing almost task
provided the task can be reduced to a series of
logical steps so that an appropriate program in
a suitable language can be fed to a computer
memory. Of course, the input and output
devices should be capable of performing the
desired task. Because of these capabilities, a
number of processes can be automated with the
help of a computer.
