Overview

2.  The first thing to
remember is that
our PC consist of
hardware and
software.
Software vs Hardware

3.  The PC hardware includes
the electronic components
that we see when we
open up the computer
case. The PC hardware, by
itself, can't really do much
of anything.
Software vs Hardware

4. Software
Software, commonly known as
programs, consists of all the
electronic instructions that tell
the hardware how to perform a
task.

5. Examples of Software

6. Hardware
 Computer hardware is
the collection of physical
parts of a computer
system. This includes all
the parts inside the
computer case, such as
the hard disk drive,
motherboard, video card,
and many others.

7.  Hardware and software are interconnected, without software,
the hardware of a computer would have no function. However,
without the creation of hardware to perform tasks directed by
software via the central processing unit, software would be
useless.

8. Input Devices
1. Keyboard
2. Mouse
3. Touch screen
Three main sources of input:

9. Keyboard
- the set of keys that are
used for a computer or
typewriter

10. Mouse
- a small device that is
connected to a
computer and
that you move
with your hand to
control the movement
of a pointer on the
computer screen.

11. Touch screen
- a type of screen on a
computer which shows
options that you can
choose by touching the
screen

12. When we press on a
particular place on the
screen, the first layer
gets bent in and
touches the second
layer, which then sends
an electrical signal to
the PC hardware
consisting of X and Y
coordinates of the
screen. Software then
does what it is
programmed to do
when we press on
particular point on the
screen.

13. Output Devices
1. Monitor
2. Audio
3. Printer

14. Monitor
- a video screen used for
display (as of television
pictures or computer
information)

15. Audio
- The second type of output
is audio. Again, today we
take audio for granted, but
in the beginning computers
could not produce audible
signals.

16. Printer
- a machine that is used for
printing documents,
photographs, etc.

17. Communication
- the ways of sending
information

18. Modularity
- having parts that can be
connected or combined in
different ways

19. The PC hardware, by itself, can't really do much of
anything. Our PC needs something that gives that
hardware set of instructions that tell it what to do.
This is what the software is used for.
