Computer – Hardware
Hardware
represents the physical and tangible components of a computer, i.e. the
components that can be seen and touched.
Examples
of Hardware are the following −
·
Input devices − keyboard, mouse, etc.
·
Output devices − printer, monitor, etc.
·
Secondary storage devices − Hard disk, CD, DVD, etc.
·
Internal components − CPU, motherboard, RAM,
etc.
Relationship between Hardware and Software
·
Hardware and software are
mutually dependent on each other. Both of them must work together to make a
computer produce a useful output.
·
Software cannot be utilized
without supporting hardware.
·
Hardware without a set of
programs to operate upon cannot be utilized and is useless.
·
To get a particular job done on
the computer, relevant software should be loaded into the hardware.
·
Hardware is a one-time expense.
·
Software development is very
expensive and is a continuing expense.
·
Different software applications
can be loaded on a hardware to run different jobs.
·
A software acts as an interface
between the user and the hardware.
·
If the hardware is the 'heart'
of a computer system, then the software is its 'soul'. Both are complementary
to each other.
