​

Answer 1

Answer:

There are various types of Registers those are used for various purpose. Some Mostly used Registers are Accumulator(AC), Data Register(DR), Address Register(AR), Program Counter(PC) as you said above there are some more like Memory Data Register (MDR), Index Register(IR), Memory Buffer Register(MBR).

-----AC(Accumulator, 16 bits) is used for all mathematical, logic, and shift operations operations except incrementing and clearing other registers

------DR (Data Register, 16 bits) is used to contain a second operand for dyadic operations such as add, sub, and, or.

-------AR (Address Register, 12 bits) is used to interface with the memory unit. All memory-references are initiated by loading the memory address into AR.

---------PC (Program Counter, 12 bits) holds memory address of current/next instruction to be executed. Updated as part of the instruction cycle.
