A program counter is a place where the address of the unit where the next instruction is located is stored.

When executing an instruction, it is first necessary to fetch the instruction from memory to the instruction register according to the instruction address stored in the PC. This process is called "fetching instruction". At the same time, the address in the PC is either automatically added by 1 or the address of the next instruction is given by the transfer pointer. After that, the instruction is analyzed and executed. The execution of the first instruction is completed, and then the address of the second instruction is fetched according to the PC, and each instruction is executed in a loop.

A program counter is a register in a computer processor that contains the address (location) of the instruction currently being executed. When each instruction is obtained, the storage address of the program counter is incremented by one. After each instruction is obtained, the program counter points to the next instruction in the order. When the computer is restarted or reset, the program counter usually returns to zero.
