Programmable Logic Controller (PLC): Programmable Logic Controller (PLC) is a specialized computer used in industrial segments to control machines and process. PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks. The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC. When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes. The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling programming language. Solenoid: The working of solenoid is based on the principle of magnetic induction. It contains a coil, frame, and a plunger known as armature. The main function of solenoid is to convert electrical signals into mechanical motion. Due to its magnetic movement, solenoid is used in different areas such as locking of two devices, interlocking of gear wheel in automobiles, and some other medical application.

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. Solve Deadlock by Footman (15 points) 1. Here is a new solution to overcome the deadlock. The Dining Philosophers decide to hire a footman whose task to allow only four philosophers to sit on the table. When entering and…
