Operating-Systems-Work

Description

This is a repository for keeping all of the work that I have completed so far for my Operating Systems class. Below I will briefly describe the purpose/Objective of each program

1.cpp

Simply introduces forking by forking a process and identifying the parent and child processes

2.cpp

Builds on 1.cpp by forking a process and having the child execute a command through using the execvp() method

3.cpp

Again, builds off of 2.cpp by having the child process execute a command given by the user and displaying the output of the command in the parent process using a pipe

4.cpp

Focus shifts to threads. This program simply creates two seperate threads and counts from 1 to 10 using them

6.cpp

Recreates the solution to the producer consumer problem. This program takes in a number of producers and consumers and creates them to do work on a buffer without producers overwritting full slots of data

7.cpp

Almost identical to 6.cpp, but the buffer is bounded

8.cpp

Recreates the solution to the Readers-Writers problem. Readers and Writers are created randomly and do work on the same buffer. No thread can enter when a writer thread is doing work, but multiple readers threads can do work at the same time. Turnstile semaphore is used to prevent writer starvation.

9.cpp

Recreates a particular solution to the Dinning Philosopher's problem, Where Philosopher's are replaced with gamers who are playing games in a living room.

Ash

The ash project is an ongoing project to implement a basic shell and learn how they fundamentally work. Currently, all built in is functional and soon regular commands will be too.
