2.
a) Your colleague has invented a new scheduling algorithm
using the multilevel queue approach. This list of processes
showing CPU burst times is below.
There are three queues used in the application. The
processes all start on the first queue and receive upto 10ms
of burst time. Once the process has received the 10ms on
the first queue, if the process still requires burst time it is
passed to the second queue where it receives upto 20ms.
Once the process has received the 20ms on the second
queue, if the process still requires burst time it is passed to
the third queue where it receives CPU time until it is
completed.
The operating system will only start allocating CPU time to
processes on the second queue when queue 1 is empty. The
operating system will only start allocating CPU time to
processes on the third queue when queue 2 is empty.
