What are the registers of the processor? a) MAR, MBR, IOAR, IOBR, PC, IR b) PSW, Sign, Zero, Carry, Equality, Overflow, Enable/Disable Interrupts...

The answer is a) MAR, MBR, IOAR, IOBR, PC, IR.

These are the common registers of the processor:

• MAR (Memory Address Register): This register stores the address of the memory location that the processor is currently accessing.
• MBR (Memory Buffer Register): This register stores the data that is being read from or written to memory.
• IOAR (Input/Output Address Register): This register stores the address of the input/output device that the processor is currently communicating with.
• IOBR (Input/Output Buffer Register): This register stores the data that is being read from or written to an input/output device.
• PC (Program Counter): This register stores the address of the next instruction that the processor will execute.
• IR (Instruction Register): This register stores the current instruction that the processor is executing.

The other options are not correct. PSW, Sign, Zero, Carry, Equality, Overflow, Enable/Disable Interrupts, Supervisor are flags that are used to store the status of the processor. CP, IR, Procesador-Memoria, Procesador-EIS, Tratamiento de Datos, Control are not registers, but they are components of the processor.
