The three systems are as follows: A) only runs one process at a time with no multipr time, but has multitasking, and C) has multitasking display the output program at a with a environment. OS Components: Programs: Word Processor a. Single cpu Calculator b. Multiple cpus A dungeon game c. File System d. Virtual Memory e. Program Interrupts Tasks: f. Timer Interrupts i. write a paper (total time 1/2 hr.) g. I/O Interrupts ii. Take a break every 5 minutes to play h. Hardware failure interrupts the dungeon game. i. Programmed I/O iii. Use the calculator to answer j. Interrupt driven I/O questions in the dungeon game. k. Direct Memory Access I/O i. Print the paper (time to print 5 l. 2 state process model minutes) m. 5 state process model Play the dungeon game while the n. Multithreading paper prints. o. Kernel level threads p. User level threads
