Programming Task: Implement a Disk Scheduling Simulator The objective of this project is to implement a simple disk scheduling simulator “ simdisk ” in C/C++ on a UNIX-based platform. SYNOPSIS: simdisk [ h ] [- n number-of-cylinders ] [ d disk-shed-policy ] [ i input_file ] DESCRIPTION: simdisk is a simple disk scheduling simulator. It takes a sequence of disk cylinder I/O requests as an input, as well as the total number of cylinders on the disk. It performs the scheduling of incoming I/O requests using the disk scheduling policy specified by the user, and measures total number of cylinders travelled by the disk head. 2.1 OPTIONS: h : Print a usage summary with all options and exit.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
