A computer register in stored program organization is a small amount of storage available as part of a CPU or other digital processor. These registers are the topmost component of the memory hierarchy and are the fastest units of memory where the CPU can store and retrieve data.

In the context of stored program organization, the computer register plays a crucial role. The stored program concept, also known as the Von Neumann architecture, is a design model for a computer that uses a storage structure to hold both the instructions for computing and the data.

Here are the steps to understand how computer registers work in stored program organization:

1. The CPU fetches the instruction from the main memory (RAM) and stores it in the Instruction Register (IR). The IR holds the instruction that is currently being executed.

2. The Memory Address Register (MAR) holds the address of the location in memory where the next instruction or the data to be fetched or stored is located.

3. The Memory Buffer Register (MBR) or Memory Data Register (MDR) holds the data fetched from, or to be stored in, the location whose address is in the MAR.

4. The Program Counter (PC) holds the address of the next instruction to be fetched from memory after the current instruction is executed.

5. The Accumulator (AC) or general purpose registers are used to hold operands for mathematical operations and the results.

In summary, computer registers in stored program organization are used to hold instructions and data that are being used by the CPU, and they play a crucial role in the execution of programs.
