Expert Solution

Step 1

Given:

Number of Processes, P = 4

Number of Resources, R = 5

Maximum Resources required by any process, n =2

So, first let us check the condition in which deadlock can never occur: P(n-1) + 1 <=R

If this condition evaluates to true in the given case, then deadlock can never occur.

P(n-1) + 1 = 4(2-1) + 1 = 4 + 1 = 5 <=5

Step by step

Write a C program which creates two childprocesses. One of the child processes mustopen data1.txt and fill it with 10 randomintegers (0-9). The other child process mustopen data2.txt and fill it with 10 randomletters (a-z). In the meanwhile, parent mustprint both child processes' id's and wait forthem to finish.
Need Code in JavaIn a multiprogramming environment, several processes may compete for a finite number of resources. A process requests resources; if the resources are not available at that time, the process enters a waiting state. Sometimes, a waiting process is never again able to change state, because the resources it has requested are held by other waiting processes. This situation is called a deadlock. Deadlock avoidance is one of the techniques for handling deadlocks. This approach requires that the operating system be given in advance additional information concerning which resources a process will request and use during its lifetime. With this additional knowledge, it can decide for each request whether or not the process should wait. To decide whether the current request can be satisfied or must be delayed, the system must consider the resources currently available, the resources currently allocated to each process, and the future requests and releases of each process.

In this question, you will consider the development of a Virtual Learning Environment (VLE)through which students manage their studies. They can watch videos, attend onlinewebinars, access forums etc. a)You are given the following requirement:“Students can select a module from a list, if they have been registered to the selectedmodule, they can see the contents.”Write out a step-by-step process for the VLE described above that a tester can use totest this requirement. b) For the VLE system, we want to ask some users to answer a questionnaire to dousability testing. Design two questions to cover effectiveness, two questions to coverefficiency and two questions to cover satisfaction. c) Write TWO requirements for the VLE, using the EARS syntax.

Answer the following sentences true or false 1. Looping is basically a phase in which we repeat the very same process multiple times u less it specifies any specific type of condition. 2. An infinite loop(sometimes called an endless loop) is a piece of coding that lacks a functional exit so that it repeats indefinitely. 3. In while loop, a condition is evaluated before processing a body of the loop.

Must use python language and file i/o system to solve the question. You are assigned the task to automate the patient management system for a hospital. Three categories of patients visit the hospital: 1. Severely ill 2. Moderately ill 3. Regular check up Your system must be able to list the patients according to the seriousness, 1 being the most serious and 3 being the least. Moreover, the system must be able to handle incoming patients while doctors are checking other patients. Solving this problem requires knowledge of Queue. Input: The input file will contain names of the patients as strings with a priority (1, 2 or 3) associated with each name and an operation called "see doctor." When the "see doctor" function will be called one patient from the queue, of course the patient who came first with seriousness 1, will be served first.

Project Objectives: This programming project is to simulate a few CPU scheduling policies discussed in the class. You will writeC++ program to implement a simulator with different scheduling algorithms. The simulator selects a task to run from ready queue based on the scheduling algorithm. Since the project intends to simulate a CPU scheduler, so it does not require any actual process creation or execution. When a task is scheduled, the simulator will simply print out what task is selected to run at a time. It outputs the way similar to Gantt chart style. Project Descriptions and Requirements: The selected scheduling algorithms to implement in this project are 1) First Come First Serve (FCFS), 2) Shortest Job First (SJF) and Shortest Remaining Time First (SRTF) OR , Priority and Preemptive Priority , and 3) Round Robin (RR). The detailed algorithms will be discussed in class. The task information will be entered from the keyboard. The format is process_id arrival_time, and burst_time.…
