BCS1333 Assignment 2 & Assignment 3

ASSIGNMENT 2

1. Describe the differences among short-term and long-term scheduling.

2. Describe the actions taken by a kernel to context-switch between processes.

3. The benefits of multithreaded programming can be broken down into four major categories (Responsiveness, Resources Sharing, Economy, utilization of multiprocessor): Briefly explain each of them.

4. Explain the three models of multithreading.

ASSIGNMENT 3

1.      There are five criterions that have been suggested for comparing CPU scheduling algorithms. List and briefly explain each of them.

2.      Consider the  following set of processes that arrive at time 0, with the length of the CPU burst given in milliseconds:

Process                        Burst Time                         Priority

P1                                 15                                3

P2                                 10                                1

P3                                 3                                  3

P4                                 5                                  2

P5                                 9                                  4

The processes are assumed to have arrives in order P1,P2,P3,P4,P5 all at time 0.

a.      Draw four Gantt charts that illustrate the execution of these processes using the following scheduling algorithms : FCFS, SJF, nonpreemptive priority ( a smaller priority number implies a higher priority), and RR (quantum = 5).

b.      What is the average waiting time of each process of the scheduling algorithms in part a?

c.        What is the turnaround time of each process of the scheduling algorithms in part a?

d.      Which of the algorithms in part a results in the minimum average waiting time (over all processes)?

3.      A file attribute is metadata that describes or is associated with a computer file. Typically there are 7 common file’s attributes. Briefly explain each of them.

4.      There are four (4) pieces of information are associates with an open file. Explain each of them

  Consider the following table 4.1. Four processes are arrived at time 0, with the length of the CPU burst given in milliseconds:

Process          Burst Time     _______ * Priority

P1                                10                                3

P2                                15                                1

P3                                3                                  3

P4                                5                                  2

*smaller priority number implies a higher priority

Table 4.1 List of processes that are arrived at time 0

The processes are assumed to have arrives in order P1, P2, P3, P4 all at time 0.

      I.        Draw FOUR (4) Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: FCFS, SJF, Priority, and RR (quantum = 5).

BCS1333 OS: DOS Command

Stands for "Disk Operating System." DOS was the firstoperating system used by IBM-compatible computers. It was originally available in two versions that were essentially the same, but marketed under two different names. "PC-DOS" was the version developed by IBM and sold to the first IBM-compatible manufacturers. "MS-DOS" was the version that Microsoft bought the rights to, and was bundled with the first versions of Windows.

DOS uses a command line, or text-based interface, that allows the user to type commands. By typing simple instructions such as pwd (print working directory) and cd(change directory), the user can browse the files on the hard drive, open files, and run programs. While the commands are simple to type, the user must know the basic commands in order to use DOS effectively (similar to Unix). This made the operating system difficult for novices to use, which is why Microsoft later bundled the graphic-based Windows operating system with DOS.

Check out the list of Basic MS-DOS Commands widely used in MS-DOS:-

1. Cd : Used to change/access directory.Prompt changes to new path of current directory. For Example: Cd [directory name]
2. cls : Used to clear command line terminal screen.
3. Del : Used to one or multiple files. For Example : DEL [drive:][path]filename
4. Dir : Used to show all files in current directory
5. Dir/p : Used to show all files in current directory page wise
6. EDIT : This command will open the file and will allow you to edit it. For example: EDIT DOS.txt
7. MD or MKDIR : This command is used to create new directory. For example : MD (NEWDIR)
8. PRINT : Used to print the specified file. For example : PRINT DOS.txt
9. RD : Used to remove any directory. For example : RD DOS.txt
10. RENAME : Used to rename a file. For example : RENAME [oldFileName][newFileName]
11. HELP : This command will display MS-DOS commands help. For example : HELP DIR
12. C: : This command is used to enter in any drive and similarly A:,D:,E: etc.
13. Copy : Used to copy a file from one location to other. For Example: COPY [oldFilePath] [newFilePath]
