Dan’s recently announced that he’s teaching n top-secret courses next semester. Instead of enrolling in them through ACORN, students need to email Dan to express their interests. These courses are numbered from 1 to n in some arbitrary order. In particular, if a student named s is interested in taking a course c, they need to sendanemailtoDancontainingthemessagec s.Notethatifastudentis interested in taking multiple courses, they need to send multiple emails, one per course. Uponreceivingamessagec s,Danlooksatthelistofstudentsalreadyenrolledin course c. If there’s already a student on the list whose name is too similar to s, Dan assumes s is the same student and ignores the message. Otherwise, he enrolls s in the course. Dan considers two names too similar if and only if they have the same length and differ in at most one letter (note that “a” and “A” are considered the same letter). For example, “Josh” and “Josh” are too similar. “Sam” and “CaM” are too similar as well. However,…
Mr. Johnson has been an independent driver for delivery services (such as Amazon Flex, DoorDash, and Uber Eats). Last month, he bought a fleet of cars and started up a business thatrents them out to other independent drivers. As the business is growing, he wants to hire youto develop a software system that helps manage the renting. The following bullet points arefrom your discussion with Mr. Johnson:• A driver needs to make a reservation for a specific type of car (sedans, SUVs, pick-ups or vans) at least 24 hours before the check-out.• A driver can request an extension for the return date/time and will be granted if thereare no reservations on that vehicle.• The renting charges are different for different types of cars. The charges will beupdated from time to time. A rent that is a week or longer may get a discount.a) Functional requirements : write at least 5 functional requirements of this softwaresystem. For each functional requirement, write the corresponding black-box test…
(3) (a) What is Base64? Show at least one application of Base64. (b) What does mount command do in UNIX? Explain with example. [You may use Internet to complete your answers. Proper citation must be provided] (4) Our CPU is currently idle and the current time is labeled time 0. Four processes arrive to the ready queue at the following times and with the following required run time: Process Arrival Time 0 1 2 3 Run Time 9 28 D Simulate the process scheduling and execution under the FCFS, SJF, and SRT scheduling algorithms. Indicate each scheduling decision, and calculate the turnaround time for each process. Also calculate the average turnaround time for each scheduling algorithm. I have started the solution below for FCFS to give an example of the format for your answer.
Create the AcmePay program for Acme Parts, which runs a small factory and employs workers who are paid one of three hourly rates depending on their shift: first shift, $17 per hour, second shift, $18.50 per hour, third shift, $22 per hour. Each factory worker might work any number of hours per week and any hours greater than 40 are paid at one and one-half times the usual rate. In addition, second-shift and third-shift workers can elect to participate in the retirement plan, for which 3% percent of the worker’s gross pay is deducted from the paychecks. Write the AcmePay program that prompts the user for hours worked and the shift number; if the shift number is 2 or 3, prompt the user to enter the worker’s choice to participate in the retirement plan (1 for "yes", 2 for "no"). Display (1) the hours worked, (2) the shift, (3) the hourly pay rate, (4) the regular pay, (5) overtime pay, (6) the total of regular and overtime pay, (7) the retirement deduction, if any, and (8) the net pay.…

Description:The project I am working on needs to demonstrate how two processes (parent and child) can communicatethrough a shared memory region, with the child process writing a value to the shared memoryand the parent process reading that value. This is my code and I wont run. Can you help: #include <stdio.h>#include <stdlib.h>#include <sys/types.h>#include <sys/ipc.h>#include <sys/shm.h>#include <unistd.h> #define SHM_SIZE 1024 /* shared memory size */ void error_exit(const char *msg) { perror(msg); exit(EXIT_FAILURE);} int main() { key_t key; int shmid; char *data; // Create a unique key for shared memory if ((key = ftok("shared_memory.c", 'R')) == -1) { error_exit("ftok"); } // Create the shared memory segment if ((shmid = shmget(key, SHM_SIZE, 0644 | IPC_CREAT)) == -1) { error_exit("shmget"); } // Attach the shared memory segment to our data space data = shmat(shmid, (void *)0, 0); if…

You are a scheduling robot assigned to schedule professors and computer science classes that meet M/W/F. There are 5 classes to schedule and 3 professors to teach these classes. Your requirements are: (1) each professor only teaches one class at a time;(2) each class is taught by only one professor; and(3) some professors can only teach some of the classes. You must produce a complete and consistent schedule. You decide to formulate this task as a CSP in which classes are the variables (named C1 through C5) and professors are the domain values (named A, B, and C). After you have solved the CSP, each class (variable) will be assigned one professor (value), and all constraints will be satisfied. The classes (variables) are: • C1, Class 1 - Intro to Programming: meets from 8:00-8:50am• C2, Class 2 - Intro to Artificial Intelligence: meets from 8:30-9:20am• C3, Class 3 - Natural Language Processing: meets from 9:00-9:50am• C4, Class 4 - Computer Vision: meets from 9:00-9:50am• C5, Class 5…

Which of the following are true with respect to a mutiprogrammed, time-shared (multi-tasking) environments? (Select all that apply.) Context-switching provides optimal use of the CPU by scheduling ready processes as soon as the CPU is available. Context switching is a zero cost operation. There is better performance when the multiprogramming level is very low. Critical sections and race conditions are a direct result of context switching and programs sharing memory.
