A program counter is a register in a laptop processor that contains the address (location) of the instruction being executed at the present time. As each instruction gets fetched, the program counter will increase its stored value by one. When every instruction is fetched, the program counter points to following instruction within the sequence. Once the PC restarts or is reset, the program counter normally reverts to zero.
