WGU C191 MODULE 2 Latest Update Graded A Temporary data such as function parameters, return addresses, and local variables. What does a stack contain? 1. The parent continues to execute concurrently with its children. 2. The parent waits until some or all of its children have terminated. 3. The child process is a duplicate of the parent process (it has the same program and data as the parent). 4. The child process has a new program loaded into it. When a parent creates a child process w...

First Come First Serve is the full form of FCFS. It is the easiest and most simple CPU scheduling algorithm. In this type of algorithm, the process which requests the CPU gets the CPU allocation first. This scheduling method can be managed with a FIFO queue. In FCFS Scheduling,  The process which arrives first in the ready queue is firstly assigned the CPU.  In case of a tie, process with smaller process id is executed first.  It is always non-preemptive in nature.
