The register which keeps track of the execution of a program and which contains the memory address of the instruction currently being executed is known as Program counter.
A program counter is a register in a computer processor that contains the address (location) of the instruction being executed at the current time. As each instruction gets fetched, the program counter increases its stored value by 1.
The program counter, PC, is a special-purpose register that is used by the processor to hold the address of the next instruction to be executed. The PLA automatically updates the PC to point to the next instruction during the op-code decode cycle.
