17. Unconditional Jump Instruction
The chapter discusses the processes involved in executing jump instructions within a computing architecture, including unconditional and conditional jumps. It emphasizes the role of program counter management, memory data registers, and the processing of flags. Additionally, it covers the significance of saving program counter values during function calls and the mechanisms for returning to previous execution contexts.

What we have learnt
- Understanding of unconditional and conditional jump instructions in computing.
- The importance of the program counter and its management during execution.
- The role of various registers, including memory data registers and flag registers, in executing microinstructions.
Key Concepts
- -- Program Counter (PC)
- A register that holds the address of the next instruction to be executed in a program.
- -- Microinstruction
- A low-level instruction that controls the internal operations of a computer's hardware.
- -- Conditional Jump
- A type of instruction that causes the program to jump to a different instruction location based on the evaluation of a condition.
- -- Unconditional Jump
- An instruction that always results in a jump to another instruction location without any conditions.
- -- Stack Pointer
- A register that points to the current position of the stack, used to store return addresses during function calls.
