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.

I suggest that you use your phone to answer although you can also use the college PCs.

Activity 1 - Inside a computer (please pay attention as there is a quiz based on the video to follow)
-
-
-
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!

Please label the diagram including in the PowerPoint. Upload into today's upload slot or add to the team folder if you are having issues.

-
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.

Session 5 - LA.B - Analogue and Digital Data - 09/01/2024
Understand the concepts, processes and implications of data transmission, including:
- the differences between analogue and digital transmission of data
- the need to convert analogue signals to digital signals and digital signals to analogue signals
- how data in a computer is represented using binary notation (bit, bytes, word length).
Understand and use binary format and the concepts of data storage, including:
- how characters can be represented in binary format and convert whole numbers into binary numbers (zero up to 10)
- conversion of binary numbers (up to 8 bits) to whole numbers (base 10)
- units used to describe memory and data storage (bit, byte, kilobyte, megabyte, gigabyte, terabyte, petabyte).
-
-
This activity is about sequences so try to do it without cheating. Look for a method of memorising the numbers and then answer the questions. Good luck!!

Activity 1 - Terminology
As you are completing Software Development, you should already be familiar with most of the terms listed below. You should also understand the need to annotate and use of of data types and data structures. Complete the form below.
- declaration, input, output, assignment, variables (local and global) and constants, sub-routines, scope of variables
- the need to annotate code to allow for maintenance
- the use of data types, including character, string, integer, real and Boolean
- the use of data structures, including records and simple arrays.
-
-
-
Flow Charts
- You can use a flow chart to help design a program. A flow chart is a diagram that shows how a program works and the routes that can be taken through it.
- A flow chart shows where the program starts, where decisions are taken, processing operations, inputs and outputs.
-
-
-
Activity 4 - create flow charts - you may want to remind yourself of the shapes used.
Create a flow chart on one of the processes below. If you finish quite quickly, challenge yourself to another.
1. The stages involved in making toast
2. To calculate the area of a rectangle
3. To authenticate a user's password
4. To authenticate a user's password and lock the account after 3 incorrect attempts.

- Find a suitable image of each and place in a word document making it clear which is the GUI and which is the CLI by labelling.
- Read through the following link and select 5 comparison points which you feel relate to you. For example, if you feel the most important thing to you is the use of graphics, you need to copy the contents of point 10 and paste into your word document.
- Compare which points others have chosen.
- Upload your word document when told into the Teams folder for today's session.
-
-
Activity 6 - Accessibility & Ease of Use of PCs and Mobile Phones - Prepare for discussion
What tools are available on a PC to make things accessible and easier to use for some people. For example, if a student has dyslexia, can you change colours?
Consider your own mobile phone. What 'tweaks' have you done to make it easier to use? What tools can be used to make it more accessible? For example, instead of writing a message, can you do something else?
-
-
You can use your phones for this activity. Go to Classpoint.app and enter the class code once it is shown.
