3. Lesson Objectives
At the end of this session you will be able to:
• Identify input and output devices
• Explore the process for computer system and their devices
Before we begin I would like you to introduce one of my
friends who actually uses computer systems within
themselves! Meet Cathy the computer!
Hi! I am Cathy and during this session I
will join Ipso in supporting you to
complete the lesson
4. Hardware
There are two main parts to a computer: hardware
and software.
Hardware is the computer equipment. A single piece of
hardware is called a device.
There are four main types of device:
• Input device
• Central Processing Unit (CPU)
• Storage Device
• Output Device
6. Output Examples
Take a look at the examples above of
how computer systems output. Please
complete Activity One. (On
Moodle)
7. Process?
So we have provided you with
examples of inputs
And examples of outputs but we have
not shown you the process. The next
slide will look at the one process a
computer system device goes through.
8. Computer System Example
Keys are pressed
on the keyboard
Which the CPU
process and
makes sense of
And the keys pressed
are displayed on the
monitor
9. Main Activity
From the examples shared in this PowerPoint it is your task to
contribute to the class forum, providing an example of a
COMPUTER SYSTEM, showing what the input, process and
output of this would be. (the Forum will close by 12 noon 3rd
February) Please note if another person has posted your idea
you will have to think of another one. So the sooner you do it
the better!
Remember if you are in Group B you will need
to complete the activity above but also complete
Activity Three!
10. Summary
So what have we learnt this lesson?
• There are two main parts to a computer: hardware and
software
• There are four main hardware devices:
Input, CPU, storage and output devices
• There are many computers that have these devices
including computers that we use in school, pelican
crossing on the road, and scanners and tills at the shop!
Homework
For next lesson you will need to upload a
picture of a device that uses a computer
system. The collaborative board is at the
bottom of this Moodle page. You must also
