Expert Solution & Answer
Chapter TG.1, Problem 2PSA
Explanation of Solution
Instruction:
When a command is given to the computer by the user is called as instruction.
Machine Instruction cycle:
- Computer processor processes certain steps for the instructions that are received in the form of machine instructions.
- The instructions that are received are processed in step by step manner based on the direction that is received from the control unit.
- Machine instruction cycle consists of different phases in reading, interpreting the instructions that are received in the form of machine language, executing the instruction code and finally storing that code.
- The below are the four steps of the machine instruction cycle
- Fetch
- Decode
- Execute
- Store
- The above mentioned steps are carried out in a repeated way to complete the instruction that is given to the computer.
- The entire process is carried out using a microprocessor.
Working of the machine cycle:
- The instruction from the main memory is being fetched.
- The instruction that is fetched from the memory gets decoded in the control unit.
- The decoded instruction gets executed in the Arithmetic Logic unit.
- After execution, the results are being stored back in to the main memory...

- A3Q3.c - You are to write a C program that implements the following disk scheduling algorithms: a. FCFS [10 marks] b. SCAN [10 marks] c. C-SCAN [10 marks] d. SSTF [10 marks] e. LOOK [10 marks] f. C-LOOK [10 marks] • 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…arrow_forward2.
