State and briefly explain two types of registers.
- Accumulator – Temporarily holds the results of the last processing step of the ALU
- Storage register – Temporarily holds a piece of data that is on its way to and from the CPU and the main memory.
- Address register – Temporarily holds the next piece of data waiting to be processed.
- Instruction register – Temporarily holds an instruction just before it is interpreted into a form that the CPU can understand
