Session 4 - LA.B - Internal components of a computer 1 - 08/01/2024
Internal components of a computer - Understand the main characteristics, functions and role of the internal components of a computer, including:
- the motherboard – printed circuit board (PCB) holding main components of the system
- central processing unit (CPU) – arithmetic and logic unit (ALU), control unit, registers
- memory (RAM, ROM, including Flash memory)
- graphics/sound/video hardware
- heat dispersal systems – fans and heat sinks
- storage devices – solid state, optical and magnetic
- how internal components of a computer affect performance and user experience
- comparison of different specifications of internal components
- how the features of the central processing unit and graphical processing unit affect performance and user experience: o clock speed o caches o multiple processing cores o heat, power consumption
- how the features of mobile devices affect performance/user experience: o System-on-a-Chip (SoC) o CPU and GPU o battery life
- comparing how mobile systems are different from traditional platforms
- how the features of memory and storage devices affect performance/ user experience: o memory (cache and RAM) o storage devices (solid state, optical and magnetic media)
- the role of computer buses in carrying data between the internal components of a computer.

Using the glossary analogy file, add an analogy for each row. Here is an example of an analogy for battery life:
Computer battery life is like a car’s gas tank – when it’s full, you can do a long way, but when it’s empty, you’re stuck and need to refuel.
Analogy helps to explain a complicated idea. It does that by comparing it to something that's easier to understand.
If you tried to explain the immune system to someone who had never heard of it, they might get lost in all the terms. If you compared it to something else, though – like a castle with walls and soldiers to defend against attacks – your explanation could get through to them more easily. That's the function of analogy!

Activity 6 - What makes a computer a computer - Video Clip
Individually, consider an analogy which could be used to explain what input, output, storage and processing actually mean in every day life. Share your examples with the rest of the class.
