Detailed explanation-1: -A program counter (PC) is a CPU register in the computer processor which has the address of the next instruction to be executed from memory. It is a digital counter needed for faster execution of tasks as well as for tracking the current execution point.
Detailed explanation-2: -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.
Detailed explanation-3: -The program counter contains the address of the next instruction. The program counter is usually the same width (number of bits) as the address bus. It is quite common in computer systems to have more memory space than actual memory.
Detailed explanation-4: -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.
Detailed explanation-5: -A program counter contains the memory location of the next instruction. We can view a program counter as a modern digital counter. It facilitates faster execution of the instructions. Furthermore, it provides tracking of the execution points while the CPU executes the instructions.
