3. Computer
Systems
• A computer is an electronic device
that receives data as input,
processes it in accordance with a
set of rules, and then generates a
product known as output.
• In today's society, a computer
system is essential for any kind of
demand.
• A computer system is a machine
that can carry out various logical
and mathematical processes and
can be customized to meet specific
needs.

4. Hardware
• Hardware is the physical
components of the computer that
we can we can touch.
• Hardware components are divided
into
-Input devices
-Output devices
-System unit

5. More on
Hardware
• Examples of Input devices are
keyboard, mouse, joystick,
scanner microphone etc
• Examples of Output devices are
printer, monitor, speaker,
headphones, web cam etc
• Examples of System Unit are
CPU, Power supply, hard disk
drive, modem, video card,
sound card etc

7. Software
• Software is the term we use for
all the programs and data that
we use with a computer system.
• Two types of software

memory. For example:
operating Systems
-Application Software is a
program designed to carry out
manual tasks. For example:
Word processors and
