How does a computer actually work? You know, like, really?
How does a computer really work? How does a central processing unit, primary and secondary memory and peripherals like a keyboard, monitor and mouse all come together to make a computer that we all use every day?
Big questions include:
This is the essence of computer science: understanding the of these machines.
Outline the architecture of the central processing unit (CPU) and the functions of the arithmetic logic unit (ALU) and the control unit (CU) and the registers within the CPU.
Describe primary memory.
Explain the use of cache memory.
Explain the machine instruction cycle.
Identify the need for persistent storage.
Describe the main functions of an operating system.
Outline the use of a range of application software.
Identify common features of applications.
Define the terms: bit, byte, binary, denary/decimal, hexadecimal.
Outline the way in which data is represented in the computer.
Define the Boolean operators: AND, OR, NOT, NAND, NOR and XOR.
Construct truth tables using the above operators.
Construct a logic diagram using AND, OR, NOT, NAND, NOR and XOR gates.
These are only displayed for our current academic year (2021 - 2022).
