MCS-44 mini project(Request)

MCS-44 mini project or Project Synopsis hello friend any one need MCS-44 mini project synopsis on WebApplication like WEB DEVELOPMENT PROJECTS Here, we will focus on investigating new ideas in application development through different projects. A set of possible project name and their details will be presented, however, students are encouraged to be creative and develop their own ideas in the given project descriptions.  1) Project Name: Online Appointment Management   Description                          A hospital provides health care appointment facility through an online portal. You can book an OPD appointment of a Doctor at the time s/he is available in the hospital. You can also book for an Appointment for a Diagnostic Test. In order to do so, a patient first needs to register for the website. Registration process involves recording patient name, address, blood group, past medi...

MCS 041 SOLVED ASSIGNMENT 2017-18

MCS-041
Operating Systems 2017- 2018
This assignment has five questions which carries 80 marks. Rest 20 marks are for viva voce. Answer all the questions. You may use illustrations and diagrams to enhance the explanation. Please go through the guidelines regarding assignments given in the Programme Guide.
1. With the aid of a diagram, describe what happens during the “fetchexecute” cycle. Include a description of how interrupts are detected. List various types of interrupts. Also explain in detail what happens when an interrupt occurs?
2. (a) Explain the meaning and importance of the following terms with respect to CPU scheduling of processes: CPU bound, I/O bound, Pre-emptive, non-pre-emptive, turnaround time, normalised turnaround time and response ratio. (6 Marks)
(b) Consider the following set of processes with arrival time and CPU execution time given in milliseconds. A process with a larger priority number has a higher priority. If any assumptions made by you, state them. Process      Arrival Time            Execution Time             Priority
 P1                0                                    03                          1 
P2                 2                                     07                         2 
P3                 3                                     04                         3 
P4                 3                                      11                         4 
P5                 7                                      05                         5
(i) Draw the Gantt charts illustrating the execution of these processes using the FCFS, SJF, Round Robin(with quantum = 2). (10 Marks)
(ii) Also calculate the average turn around time, average waiting time, processor utilization and throughput for each of the algorithms mentioned in (i).
 (c) Explain the trade-offs involved in choosing the size of a time slice for a round robin algorithm (4 Marks)
 3. Describe the following disk scheduling policies: First Come First Serve (FCFS), Shortest Seek Time First, SCAN, C-SCAN, Look and C-Look. Show the disk arm movement and calculate the number of tracks traversed using all of the policies if the disk has 200 tracks and the requested tracks, in the order received, are 55, 58, 39, 18, 90, 160, 150, 38, 184. (20 Marks)
 4. Write an interactive C/C++ program for implementing the Banker's Algorithm. (10 Marks)

5. Discuss in detail the features, Process management, Memory management, I/O Management, File management and Security and Protection in Linux Operating System.
