An operating system is the fundamental software that manages your computer’s hardware and software resources, enabling you to interact with it seamlessly. It acts as an intermediary between you, your applications, and the physical components of your device.
Operating Systems Tutorial
Key functions of an operating system include
- Process management: Executing and coordinating multiple programs and applications simultaneously.
- Memory management: Allocating and managing system memory for efficient use.
- File management: Organizing, storing, and retrieving files on storage devices.
- Device management: Controlling and interacting with hardware components such as the CPU, keyboard, mouse, and printers.
- Security: Protecting system resources and data from unauthorized access.

Containerization
Containerization involves packaging software applications and their dependencies into a container that can be easily deployed across different computing environments. Containers provide a lightweight, portable way to package and deploy software applications, making it easier to manage and scale applications in modern computing environments. Containerization is commonly used in cloud computing environments and is becoming increasingly popular for deploying microservices-based applications.
What is the best book on operating systems?
I recommend reading two books: one general text (that is, a book on concepts and theory) and one implementation text (that is, a book about a specific OS).
For the general text, I recommend Operating System Concepts (2012) by Silberschatz, Galvin, and Gagne. Also known as the “dinosaur book,” due to the irrelevant dinosaurs gracing the covers of the book’s many editions, this is a great introduction to OS design.
Another favorite is Operating Systems (2003) by Deitel, Deitel, and Choffnes. It features excellent case studies that put theory to practice.
