A thread, often considered the smallest unit of processing that can be scheduled by an operating system, is a component of a process. Multiple threads can exist within the same process, sharing certain resources while operating independently in execu...
Multi-CPU I/O + CPU Scheduling In a computing environment, we have two Central Processing Units (CPUs) and five distinct processes. Each process arrives at the system at a unique, random time and undergoes the following sequence: First CPU Burst: Up...
FCFS P1: Arrival Time = 2, Burst Time = 6 P2: Arrival Time = 5, Burst Time = 2 P3: Arrival Time = 1, Burst Time = 8 P4: Arrival Time = 0, Burst Time = 3 P5: Arrival Time = 4, Burst Time = 4 Determine the order of completion, and calculate the average...
Using an example, let's illustrate how First-Come, First-Served (FCFS) process scheduling works in an operating system. We'll consider four processes, P1 to P4, each with its own arrival and burst times. We will then calculate the response, waiting, ...
Deadlocks occur when four necessary conditions hold simultaneously. These conditions, known as the "Four Conditions for Deadlock," are: Mutual Exclusion: This condition means that at least one resource must be non-sharable, meaning only one process...
A deadlock is a situation in computer science and concurrency theory where two or more processes or threads are unable to proceed with their execution because they are waiting for resources held by each other, causing a standstill. In a deadlock, non...
