Program Counter
The register which keeps track of the execution of a program and contains the memory address of the instruction which is to be executed next is known as the Program Counter.
Explanation:
A program counter is a register that stores the address of the next instruction to be executed in a program. It is a special-purpose register that is used by the processor to keep track of the execution of a program. Whenever a program is executed, the program counter is incremented to point to the next instruction in the program. The program counter is a crucial component of the execution cycle of a processor, as it is responsible for determining the order in which instructions are executed.
The program counter is also known as the instruction pointer, instruction address register, or simply as the PC. It is an essential part of the processor's control unit, which is responsible for controlling the flow of data in the processor.
Conclusion:
In conclusion, the program counter is a register that keeps track of the execution of a program and contains the memory address of the instruction which is to be executed next. It plays a crucial role in the execution cycle of a processor and is an essential component of the processor's control unit.
