a$)(10$ points$)$ Consider a system of processes and resources and make the following assumptions:

The Ready List $($RL$)$ has $3$ priority levels, $0,1,$ and $2(0$ being the lowest$).$

The create function is simplified: create$(n)$ creates a new child process with the priority $n.$

The process is placed at the end of the corresponding RL queue.

Only a single CPU exists. The currently running process continues running until the process:

o blocks by requesting an unavailable resource, or

o is interrupted by a function timeout$(),$ which moves the process from the head of

the current RL queue to the end of the same queue; the process currently at the

head of the RL queue starts running

The system has $3$ resources, $0,1,2.$

At the start, only a single process, described by PCB $0,$ exists and is running at priority $2.$

Assume the following sequence of functions is issued $($each function is executed by the currently running

process$).$ The create function always uses the next available PCB $1,2,3,$dots :

create $(2)$

create $(1)$

timeout$()$ Pl

A$.$ request $(1)P1$

timeout $()-PD$

request$(2)$

$7.)$ request$(1)$ blocked

request$(2)-$p$1$ blocked

timeout$()-82$

create$(1)$

I. Determine how many child processes each process has, and what processes are blocked at

the end of the above sequence. Show or mention the name of each child process and the

RCBO

resource the process $is$ blocked $on.E.g.PCB2$ has children $1,2$ and PCBO $is$ blocked $on$

$po$ has $2$ children $(1$:$2),P_2$ has child $P_3$

$Po.PI$ are blocked

$PCBDis$ blocked $onRCB$

PCBI $is$ blocked $onRCB2$

can someone help me understand this $?$
