What does the machine code 901 do?
What does 3XX do?
If 501 tells the computer to load the data at mail box 1, what is the correct terminology for the following parts of the instruction:
5XX –
X01 -
Waits for input from the user
Stores data in accumulator in a specified mail box number
5XX – op code
X01 – operand

2. Identify computer hardware, their purpose and upgrade possibilities
Learning AIM
Identify computer hardware, their purpose and upgrade possibilities

3. Learning objectives
Describe common storage technologies such as optical, magnetic and solid state
Describe the difference between RAM and ROM
Understand the need for input and output devices
State the purpose of the CPU

4. Learning outcomes By the end of this lesson you will be able to ....
ALL
(C)
Identify RAM, ROM, CPU, secondary storage and where input / output devices connect to the mother board.
Describe how data is moved around the system
MOST
(B)
Also be able to describe the purpose of each hardware component
SOME
(A)
Also be able to describe in detail the purpose of each hardware component, giving details about how each could be upgraded

5. Describe common storage technologies such as optical, magnetic and solid state
Describe the difference between RAM and ROM

Learning
objectives
Independent Task
Working in groups take apart the computer. Take it in turns!
In your books copy and complete:
Name of component
If storage what type?
Location
Purpose
Upgradable?
Connects to?
RAM
Primary
On mother board
Stores data, OS, programs that are currently running / in use
Yes – you can install a larger capacity RAM increasing multi-tasking capabilities
CPU via a bus
Hand out instruction sheets – double check students know to wear gloves – discuss static build up and that some people like to take shoes and socks off to avoid this.
Discuss what to check for (computer turned off, left off for an hour before opening etc)

6. Fill in the keywords based on what the class think they should be

7. Learning outcomes I can .... ALL MOST SOME
