Jump Command

If the program counter is always one count ahead of the memory locations from which the machine code is being fetched, how does the microprocessor change the sequence of program execution with a "Jump" execution?

During a jump instruction, the program counter is loaded with a new address that is not necessarily the address of the next sequential instruction. After a jump, the program execution continues from the new location in memory.
