- Question
What is a data register and address register?
- Correct Answer
- Data registers - can be assigned to a variety of functions by the programmer They can be used with any machine instruction that performs operations on data Address registers - contain main memory addresses of data and instructions or they contain a portion of the address that is used in the calculation of the complete addresses
