In a computer system, which of the following is NOT typically a function of the bus? (GATE 2021)

• Data transfer between CPU and memory.

• Control signal transmission between I/O devices and CPU.

• Execution of arithmetic operations.

• Addressing of memory locations.

What is the primary purpose of bus arbitration in a multiprocessor system?

• To ensure memory is not accessed simultaneously by multiple processors.

• To manage the communication between I/O devices.

• To control the execution of instructions in the CPU.

• To determine which processor has control of the bus at any given time.

Which of the following best describes a "stack organization" in computer architecture? (GATE 2019)

• Data is stored in a sequential manner and accessed by address.

• Data is organized in a Last-In-First-Out (LIFO) manner.

• Data is stored in fixed-size blocks with direct access.

• Data is organized in a First-In-First-Out (FIFO) manner.

How is the "general register organization" typically implemented in a CPU (GATE 2020)

• With a single register used for all operations
