•
Your program will service a disk with 300 cylinders numbered 0 to 299.
•
•
•
•
The program will service the requests (a list of 20 cylinder numbers) given in the file
request.bin.
This file contains (4 byte) integer values representing requests ranging from 0-299.
Your program will take the initial position of the disk head as the first command line
argument and the direction of the head as the second command line argument.
It will then output the requests in the order in which they are serviced, and the total
amount of head movements required by each algorithm.
In particular, your program needs to do the following:
Your program should take two command line arguments
a) First command line argument - initial position of the disk head (an integer value)
b) Second command line…

That EFA takes 6 one bit inputs: aj, bj, Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit outputs: sj, Cout and rout. The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs.

Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation. This project will involve managing a contiguous region of memory of size MAX where addresses may range from 0 ... MAX - 1. Your program must respond to four different requests: 1. Request for a contiguous block of memory 2. Release of a contiguous block of memory 3. Compact unused holes of memory into one single block 4.…arrow_forward
