Classroom Note:
Random Access Memory (RAM)
Random Access Memory, commonly known as RAM, is a type of computer memory that is used to store data that is actively being used or processed by a computer at any given time.
Uses Of RAM
- Running applications
- Multitasking
- Operating system functionality
- Temporary storage of Data
- Gaming performance
Control Unit (CU)
The Control Unit, often abbreviated as CU, is a critical component of a computer’s central processing unit (CPU). It manages and directs the operations of the entire CPU, ensuring that data and instructions are processed in the correct sequence and at the right time.
Uses Of CU
- Instruction execution
- Coordination of data movement
- Arithmetic and logic operations (Calculations)
- Clock signal
Evaluation:
- What is the role of Random Access Memory (RAM) in a computer system?
- List two uses of the Control Unit (CU) in a computer.
Note to Teachers:
Customize the lesson content, teaching methods, and pupil activities to suit your teaching style, curriculum, and available resources.
