A network is a group or system of interconnected people or things, such as computers, telephones, or social media platforms, that are able to communicate and share information with each other. It can also refer to a group of individuals or organizations that are linked together for a common purpose or goal. In the context of technology, a network typically refers to a system of computers and other devices that are connected to each other to share resources and information.

Definition:
A network is a group of interconnected devices (nodes) that can communicate and share resources with each other. It enables the exchange of data, applications, and services between various endpoints.
Components:
- Nodes: The individual devices within the network, such as computers, servers, printers, and IoT devices.
- Links: The physical or logical connections that establish paths for data transmission between nodes.
- Protocols: The set of rules and standards that define how nodes communicate with each other, ensuring interoperability.
- Network Interface (NIC): The hardware component that connects a node to the network and allows it to transmit and receive data.
- Addressing: The scheme used to identify and locate specific devices within the network.
Types of Networks:
- Local Area Network (LAN): A network that connects devices within a limited geographical area, such as a home, office, or building.
- Wide Area Network (WAN): A network that spans a larger geographical area, connecting devices across cities, regions, or countries.
- Virtual Private Network (VPN): A secure network that allows remote users to access a LAN over the internet.
- Metropolitan Area Network (MAN): A network that connects devices within a metropolitan area, larger than a LAN but smaller than a WAN.
Network Topologies:
- Bus: All devices are connected to a single shared cable.
- Ring: Devices are connected in a circle, with data flowing in one direction.
- Star: All devices are connected to a central hub or switch.
- Mesh: Devices are connected to multiple other devices, creating redundant pathways for data transmission.
Benefits of Networks:
- Resource sharing: Devices can access and utilize shared resources, such as files, printers, and databases.
- Improved communication: Networks enable efficient and instant communication between devices, regardless of their location.
- Reduced costs: Sharing resources allows organizations to optimize infrastructure and reduce expenses.
- Flexibility and scalability: Networks can be easily expanded or modified to meet changing needs.
- Enhanced security: Network security measures protect data and prevent unauthorized access.
