It’s been a month since, and with all my college commitments wrapping up just yesterday, I wanted to take a moment to reflect and express my thoughts. After completing my plus two, engineering was never my first choice. I was interested in physics and composing music and had a strong desire to pursue my studies in those fields. I was unaware of the opportunities in engineering, and I couldn't find anyone to guide me. Due to certain circumstances, I had to let go of my passion and ended up just attending the KEAM exam. In the first allotment, I was selected to one of the engineering colleges in Kollam. As the admission procedure began I realized I wasn’t very interested in long studies. So I rearranged my option list prioritizing LBS College of Engineering, Kasaragod. In the subsequent allotment, I got admitted to LBSCEK. I was genuinely curious about studies until my plus two, but after taking admission, that interest slowly faded. Looking back now, I feel it was mainly ...

 First Come First Serve (FCFS) - CPU Scheduling Algorithm what is FCFS CPU Scheduling Algorithm ?                         First Come First Serve (FCFS) is a scheduling algorithm that automatically executes queued requests and processes in the order they arrive. Source Code #include <stdio.h> void main() { int i=0,pid[10],at[20],ct[20],bt[20],tat[20],wt[20],n=0,j=0; float avgw=0,avgtat = 0; printf("Enter the number of proccess : "); scanf("%d",&n); printf("Enter details of each process :\n");         for(i=0; i<n; i++) { printf("Enter the proccess id :"); scanf("%d",&pid[i]); printf("Enter arrival time : "); scanf("%d",&at[i]); printf("Enter Burst Time : "); scanf("%d",&bt[i]); printf("\n"); } //Sort the process based on arrival time using bubble sort int temp =0; for(i=0; i<n-1; i++) { for(j=0; j...

CPU Scheduling Algorithms In Operating Systems What is CPU scheduling algorithm and why it should need in operating systems? Refers to switching between processes that are being executed. Basics of multi programmed operating systems This Switching ensures that CPU utilisation is maximised so that computer become so productive There are two main type of CPU scheduling 1. Preemptive CPU Scheduling 2. Non-Preemptive CPU Scheduling Type of CPU Scheduling 1. Preemptive CPU Scheduling Used when the process switches from the running state to the ready state or from waiting state to ready state In preemptive scheduling, the operating system can interrupt a currently running process and move it out of the CPU to allow another process to run. This interruption can occur based on priorities, time slices (quantum), or some other criteria.           Example:  Round Robin, Priority Scheduling 2. Non-Preemptive CPU Scheduling In non-preemptive scheduling, once a proc...
