What is an Operating System?

An operating system (OS) is the fundamental software that manages computer hardware and provides various services for computer programs. It serves as a bridge between users and the computer’s hardware, enabling users to interact with their devices through a user-friendly interface. The OS is responsible for tasks like managing files, running applications, handling hardware resources, and ensuring system security.

Why is it necessary, understanding Operating Systems (OS) and how they work?

Understanding Operating systems, working and its functions are essential because they simplify and abstract the complexity of hardware, making it easier for users and software applications to communicate with the computer. Without an OS, users would need to interact with hardware directly, which can be complicated and prone to mistakes.

The OS provides a consistent and organized way to access and manage hardware resources, ensuring efficient and secure operation.

What is a Kernel?

The kernel is one of core component of any operating system. It acts as an intermediary between the hardware and software layers, managing system resources, and providing essential services. The kernel handles tasks like process management, memory management, device management, and system calls. It’s the foundation upon which the entire operating system is built.
