# Description

The project was a simulation of a real operating system, where OS manages resources and processes. Java was the programming language to develop this project.

# Features & Functionalities

- Interpreter that reads a text file representing a program and starts executing it and handles common instructions like printing a variable, assigning a variable and reading/writing to a file.

- Mutexes to ensure mutual exclusion over the critical resources.

- Scheduler that schedule processes in the system to ensure all processes gets a chance to execute. Scheduling algorthim used was Round Robin. 

- System calls that reads and writes data from disk and memory

- Memory that's shared by all processes to store program code and variables that processes need to complete execution. In case memory doesn't fit, a LIFO (Last In - First Out) replacement algorthim was used.

- A Process Control Block (PCB) for each process to store all information about a process including process ID and state.
