Assume there are three processes A, B and C. Process A executes for 3 milliseconds and then does I/0 for 2 milliseconds. Process B executes for 2 milliseconds and then does I/0 for 2 milliseconds and then executes again for another 3 milliseconds. Process C executes for 3 milliseconds and then does I/0 for 2 milliseconds. All these processes executes twice. What is the Total Job Duration?

A, B, C, D, and E are five (5) processes that are awaiting execution. Their respective predicted burst times (in ms) are 10, 5, 8, 2, and 5. These events occur at times of 23, 12, 0, 5, and 15 milliseconds, respectively. use the FCFS algorithm to plan the execution
Suppose two CPU A and B have exactly the same circuits, but different clock frequencies. Answer the following questions: a) If the clock frequency of CPU A is 8MHz, how long is one clock cycle of CPU A? b) If the CPU A can execute 0.4 million instructions per second on average, how long is the average time to execute one instruction? c) What is the average number of clock cycle to execute one instruction for CPU A? d) The frequency of CPU B is 12MHz. What is the average number of instructions that can be executed per second?
Computer Science Suppose for a processor system it takes 35 cycles to push and pop registers onto the stack and change the PC value to the start of the interrupt service routine (ISR) or return from it. Suppose also that the ISR software takes additional 45 cycles to store the process state before the actual ISR body begins its work, and suppose it takes the same number of cycles to restore the process state when ISR is finished. If the ISR body takes 1000 cycles, what is the percent total overhead every time the ISR is executed? If the processor is running at a 2 GHz clock frequency, how long does it take before the ISR body begins execution in nanoseconds? This is usually called the ISR latency
The arrival time for processes A,B,C and D are 0,2,4 and 5 respectively and the burst time are 7,4,1 and 4 respectively. what is the average waiting time?
Suppose you have a computer that does instruction processing in anatomic way, with a clock cycle of 7ns and one instruction executioncompleted every cycle.You now split the processing into the five stages of the RISC pipeline,and you get required processing times of• IF: 1ns• ID: 1.5ns• EX: 1ns• MEM: 2ns• WB: 1.5nsYou now have added 0.1ns of delay between each of these stages. What’s the clock cycle time of this 5-stage pipelined machine?

Assume that the 8051 serial port is connected to the COM port of IBM PC, and on the PC, we are using the terminal.exe program to send and receive data serially. P1.1, P1.2, and P1.3 of the 8051 are connected to a red LED, a green LED, and a switch, respectively. Write an 8051 assembly program to send to PC the message “CSE 36[1]” continuously after activating the switch. During the data sending period make the green LED on and red LED off. After the completion of sending the data make both the red and green LED off.
