REGISTER

WHAT IS A REGISTER ?

• The computer hardware for storing one machine word.

• A small, high-speed computer circuit that holds values of internal operations, such as the address of the instruction being executed and the data being processed.

• When a program is debugged, register contents may be analyzed to determine the computer's status at the time of failure.

• In microcomputer assembly language programming, programmers look at the contents of registers routinely. Assembly languages in larger computers are often at a higher level.
