📘 What is an Operating System?
An operating system (os) is software that manages hardware resources and offers services to computer programs. The important roles of an operating system include:
- Managing hardware and software resources
- Controlling input and output operations
- Managing processes and memory
- Providing security and file management
- Facilitating user interaction with the computer
An in-depth understanding of these concepts is crucial for every engineer, especially when it comes to real-world applications.
