 Broadly, O.S. (Operating System) refers to the fundamental software that manages a computer's hardware and software resources, providing a platform for applications to run. It acts as an intermediary between users and the computer hardware, ensuring efficient operation and user convenience.

Key functions of an operating system include:

1. Resource Management: Manages hardware resources like the CPU, memory, storage, and input/output devices.

2. Process Management: Handles the creation, scheduling, and termination of processes.


3. File System Management: Organizes and controls data storage, retrieval, and access.

4. User Interface: Provides a user interface, such as a command-line interface (CLI) or graphical user interface (GUI), for interaction.

5. Security and Access Control: Protects data and system integrity by managing permissions and authentication.

6. Error Handling: Detects and manages system errors to ensure stability.

Examples of operating systems include Windows, macOS, Linux, Android, and iOS, which cater to a variety of devices like desktops, servers, and mobile devices.

STRUCTURE OF NETWORK - There are two types of network point-to-point network multipoint networks. Point to point network - Point to point network in this type network there are two devices connected to each other data flow in this type network, local network to remote network, ex- satellite ,television ,microwave. Multi point - In this type network multi-device share of network it is also called multi drop connection. Structure of Topology - 1.physical topology 2. logical topology. Pysical topologies - In this Type Topology, it reffer To Connect All Device Physically.it means the physical shape of network. Logical Topologies - The Network Create Different Type But Actually Work's Logically.( it's shape is different). Type of Topologies - Single node, Star bus, Ring, Mesh,...
