Answer:
By sending the address of next instruction to be run
Answer:
by sending the address of next instruction to be run.
Explanation:
by sending the address of next instruction to be run is used for controlling sequence of instruction execution.
sequence of instructions is stored in memory.
The memory address wherever the first instruction is found is copied to the instruction pointer.
The CPU sends the address within the instruction pointer to memory on the address bus.
The CPU sends a “read” signal to the control bus.
Memory responds by sending a copy of the state of the bits at that memory location on the
data bus, that the CPU then copies into its instruction register.
The instruction pointer is automatically incremented to contain the address of the next
instruction in memory.
The CPU executes the instruction within the instruction register.
