HOMEWORK 2 - MULTIPROGRAMMING\ DUE: 02/02/2024 11:59 PM\ POINTS: 50 (10 POINTS PER QUESTION)\ a) Define single programming and multiprogramming.\ b) Describe a scenario where multiprogramming might be better than single programming.\ Note: You may use the internet to research any applications or describe an example from your personal experience.\ Suppose P1, P2, P3, and P4 are ready to run (in this order). P1 executes for 4 time units, P2 executes for 5 time units,

P3

executes for 2 time units, and P4 executes for 3 time units. Neither process invokes I/O. Assuming that a timer interrupt occurs every time unit, fill in the table:\ \\\\table[[Time (in units),Running,Queue of Processes Ready to Run],[
