Expert Solution & Answer
Chapter 9, Problem 1RQ
Explanation of Solution
- A system that is designed in transforming the data into information is called as information system.
- It is also used in managing both information and data.
- It provides condition for gathering the data, storing the data, and retrieving the data.
- It is comprised of hardware, software,
databases , procedures, and peoples.
Purpose of information system:
- The main purpose of the information system is that it enables good decision making by making the availability of the relevant and timely information to the decision makers.
- Decisions are generally made based on the information that is available to the requested user at the required time.
- It helps decision makers to analyze the information provided and infer a required decision.

After playing our giving implementation, your task is to implement Dinning Philosophers
with semaphore in C, by including and
Your implementation will require creating five philosophers, each identified by a number
0.4. Each philosopher will run as a separate thread. Create threads using Pthreads
as discussed in the Lecture slides on Chapter 4 and Practice Lab on Threads.
Your solution needs to accomplish the following:
Implement in C (15 points)
1. dp1.c - You are to provide your solution to this assignment as a single C program
named 'dp1.c using semaphore. Explain in you code (as comments) that the dead
lock will happen or not. If there is a possible deadlock, you can simply solve the
deadlock by pick the fork in order like the first solution in our slides.
