How does an interrupt signal a CPU? Group of answer choices By directly modifying the CPU's registers By writing to a specific memory location By pausing the CPU's execution By sending a signal to the CPU's interrupt controller

Which one of the following most correctly describes the functionality of the control unit in a CPU? To perform arithmetic operations based on decoded program instructions To store program instructions To perform logic operations based on decoded program instructions To generate control signals based on decoded program instructions When an interrupt occurs, which one of the following takes place? Execution of the current instruction is completed, and the address of the next instruction is saved before the interrupt service program starts Execution of the current instruction is aborted, and its address is saved before the interrupt service program starts Execution of the current instruction is completed, and the interrupt service program starts Execution of the current instruction is aborted, and the interrupt service program starts

"When an interrupt occurs; which of these functions would be the first to occur? the program counter and other registers' values are pushed onto the stack interrupt service routine executed the registers are restored by popping their values off of the stack the processor identifies the source of the interrupt"
Dominador T.
Select the correct alternative from the given choices. What will be the response of the CPU, on receiving an interrupt from an input/output device? (A) It hands over the control of address bus and data bus to the interrupting device. (B) It branches off to the interrupt service routine after completion of the current instruction. (C) It halts for a predetermined time. (D) It branches off to the interrupt service routine immediately.
