A printer is requesting processor servicing using handshake communication. Assume ireq and iack are initially 0's. Which XXX completes the given order of events? ireq = 1 Device waits XXX ireq = 0 iack = 0 Question 19Select one: a. iack = 0 b. ireq = 0 c. ireq = 1 d. iack = 1

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.

Complete the missing sequence numbers (Seq), acknowledgement numbers (ACK), and segment length (LEN) in the following TCP Reno sender, receiver connection. Assume: (i) No timeouts occur. (ii) The connection is full-duplex. (iii) The sender and receiver always have data to transmit. (iv) There are no delayed acknowledgements at the sender or receiver. (v) The initial TCP handshake has already been completed.

"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"
