Define Register and give examples of Special Purpose and General Purpose Registers. Differentiate between them and between registers and main memory.

Here are the solutions to the questions:

(d) Give two examples of Internet Protocol.

1. Transmission Control Protocol (TCP)
2. Internet Protocol (IP)

3. a) Define the term Register.
A register is a small, high-speed storage location within the Central Processing Unit (CPU) used to temporarily hold data, instructions, or memory addresses that the CPU is currently processing.

3. b) Give one example of:

• i) special purpose register:
  • Program Counter (PC)
• ii) general purpose register:
  • Accumulator (ACC)

3. c) Give one difference between special purpose register and general purpose register.

• Special purpose registers are dedicated to a specific function within the CPU (e.g., storing the address of the next instruction), while general purpose registers can be used by the programmer for various data manipulation tasks.

3. d) Outline two differences between register and main memory using Table 3.

$$\begin{array}{|c|c|c|} \hline & \textbf{Register} & \textbf{Main Memory} \\ \hline \text{i)} & \text{Located inside the CPU.} & \text{Located outside the CPU (RAM modules).} \\ \hline \text{ii)} & \text{Extremely fast access speed.} & \text{Slower access speed compared to registers.} \\ \hline \end{array}$$
