  11. computer systems and how they are built a computer system is a combination of hardware and software working together to solve a problem.

  12. Components of computer systems computer systems are made up of three important components. They are hardware, software, and a real time operating system.

  13. Hardware : There are a range of hardware components found in an embedded system. These include: Computer system hardware components CPU/ Microcontroller

  14. Activity 3: https://www.mauthor.com/present/6539032091295744 Mariam and Sultan are trying to separate components into a hardware or software category. Help them to complete the activity below by matching the component with either hardware or software.

  15. CPU What is a CPU? The CPU (Central Processing Unit) is the 'brain' of a computer. Analogize it to the human brain - the decision-maker and controller. Why is it Called 'Central’? Explain that it's called 'Central' because it's at the core of the computer, where most processing happens. Inside the CPU: Illustrate the internal components: • Arithmetic Logic Unit (ALU) • Control Unit (CU) • Registers • Memory

  16. CPU How Does a CPU Work? Explain the CPU's primary function: Decode: Interpret the instructions. Fetch: Get instructions from memory. Execute: Perform calculations or operations. Store: Save results back in memory.

  17. Each hardware component has its own use within the computer system. Here’s how each one is used. Powersupply For a computer system to work properly, it needs a smooth power supply. A wall adapter or a battery can both be used as a power supply. Microcontroller An computer system either has a microcontroller or a microprocessor. It is the main brain inside an computer system.

  18. Microcontrollers A microcontroller is a computer chip that is used instead of a CPU. It contains a processor, memory, as well as inputs/outputs. Products such as mobile phones, TV’s and washing machines all use microcontrollers. Some examples of educational microcontrollers include:

  19. Each hardware component has its own use within the embedded system. Here’s how each one is used. Memory Memory is key for storing important information in the computer system. There are two types of memory – RAM (random access memory) and ROM (Read-only-memory)..

  20. Each hardware component has its own use within the embedded system. Here’s how each one is used. Communication port There are a few different communication ports that can be used to create communication with other computer systems. An example is a USB. Output / Input To interact with the embedded systems, we need input. The input can be provided by the user or by sensors.

  21. Activity 4: https://wordwall.net/resource/60696355 Mariam and Sultan are learning about embedded system. Mariam wants to test Sultan’s knowledge on what he’s learnt. Help Sultan to complete the activity below by matching the name with the definition.

  24. Memory: Memory is where the computer stores or remembers data. There are two types of memory in a computer. Both have an important role in helping the computer to run. They are further broken down into sub-categories. These are: • Primary storage • RAM • ROM • Secondary storage • HDD • SSD • USB flash drive

  25. https://www.mauthor.com/embed/5612803041394688 Activity 5: Mariam and Sultan are learning about memory. Help them to complete the activity below by matching the memory type with the storage.

  26. Primary Storage: Primary storage is the part of the computer that holds data, programs and instructions that are currently in use. It is also known as the main memory. It is internal which means it is fixed inside the computer. It is found in the memory slot on the computer motherboard. There are two types of primary storage; Random-Access-Memory, also known as RAM and Read-Only-Memory, also known as ROM.

  27. RAM RAM is the main place that data and instructions are stored when a program is being used. When a program such as the internet is open, it loads from the Hard Disk Drive and then placed into RAM. This lets the program communicate with the processor at high speeds. RAM is known as ‘random access memory’ because data can be written and read quickly in any order. The more RAM you have, the quicker your computer will be. This is because it will be able to do more things at the same time. It is known as volatile memory. This means that data is lost when the computer is switched off because it needs power to hold information.

  28. ROM ROM is used to store the start-up instructions for the computer which is also known as firmware. ROM also performs large input/output tasks and protects programs or software instructions. ROM is a lot slower than RAM. It is known as non-volatile memory. This means that data is not lost when the computer is switched off, and it does not need power to hold information - it is stored permanently in the computer.

  29. RAM vs ROM RAM and ROM are both forms of primary storage. As you can see, they each play their own roles in the functioning of a computer. Below are the main differences between RAM and ROM.

  30. Activity 6: https://www.mauthor.com/embed/6649361211195392 Mariam and Sultan are learning about primary memory. Help them to complete the activity below by choosing whether the statements below are true or false. True False True False True True False True

  31. HOT Question Imagine you're designing a computer game. How would the amount of RAM in a computer affect the gameplay experience? What considerations should you keep in mind when deciding how much RAM your game requires? 3 min

  32. Secondary Storage: Secondary storage is a type of memory known as external memory or back-up. It is slower than the main, primary memory of the computer. Just like the ROM, it is non-volatile. These types of storage are used for storing data/information permanently. The CPU cannot directly access the files in these memories. They are first transferred from the primary memory to the secondary memory.
