Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods.

Object

Objects are basic run-time entities in an object oriented system, objects are instances of a class these are defined user defined data types.

LRU (Least Recent Used) page replacement algorithm

#include<stdio.h>

int findLRU(int temp[], int n){
	int i, pos = 0, minimum = temp[0];
	
	for(i = 1; i<n; i++){
		if(temp[i] < minimum){

Notes for operating system ( Md. Hasinur Rahman )

Swapping

Swapping is a mechanism in which a process can be swapped temporarily out of main memory (or move) to secondary storage (disk) and make that memory available to other processes.

Process

A process is basically a program in execution. The execution of a process must progress in a sequential fashion.

Scheduling

The act of determining which process is in the ready state, and should be moved to the running state is known as Process Scheduling.
