We are given with the n number of processes i.e. P1, P2, P3, ..., Pn and their corresponding burst times. The task is to find the average waiting time and average turnaround time using FCFS CPU Scheduling algorithm.What is Waiting Time and Turnaround Time?Turnaround Time is the time interval between the submission of a process and its completion.Turnaround Time = completion of a process – submission of a processWaiting Time is the difference between turnaround time and burst timeWaiting Time = turnaround time – burst timeWhat is FCFS Scheduling?First Come, First Served (FCFS) also known as First In, First Out ...

Structure is a collection of different datatype variables, grouped together under a single name.Features of structureThe features of structure in the C programming language are as follows −It is possible to copy the contents of all the structure elements of different datatypes to another structure variable of its type by using an assignment operator.For handling the complex datatypes, it is better to create structure within another structure, which is called nested structures.It is possible to pass an entire structure, individual elements of structure and an address of structure to a function.It is possible to create structure pointers.Declaration and initialization of ...

You can pass arrays to a method just like normal variables. When we pass an array to a method as an argument, actually the address of the array in the memory is passed (reference). Therefore, any changes to this array in the method will affect the array.Suppose we have two methods min() and max() which accepts an array and these methods calculates the minimum and maximum values of the given array respectively:Example Live Demoimport java.util.Scanner; public class ArraysToMethod { public int max(int [] array) { int max = 0; for(int i=0; imax) { ...

Routers are networking devices operating at layer 3 or a network layer of the OSI model. They are responsible for receiving, analysing, and forwarding data packets among the connected computer networks. When a data packet arrives, the router inspects the destination address, consults its routing tables to decide the optimal route and then transfers the packet along this route.Features of RoutersA router is a layer 3 or network layer device.It connects different networks together and sends data packets from one network to another.A router can be used both in LANs (Local Area Networks) and WANs (Wide Area Networks).It transfers data ...

The DateTime.Compare() method in C# is used for comparison of two DateTime instances. It returns an integer value, 0 − If date1 is later than date2SyntaxFollowing is the syntax −public static int Compare (DateTime d1, DateTime d2);Above, d1 and d2 are the two dates to be compared.ExampleLet us now see an example to implement the DateTime.Compare() method −using System; public class Demo { public static void Main(){ DateTime d1 = new DateTime(2019, 11, 20, 6, 20, 40); DateTime d2 = d1.AddYears(5); Console.WriteLine("Initial DateTime = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ", d1); ...
