A computer network is a system that allows multiple computers to communicate with each other and share resources such as files, printers, and internet connections. Networks can be classified based on their size and scope, ranging from small local area networks (LANs) within a single building to large wide area networks (WANs) that span across cities or even countries. Networks can be wired or wireless, and can use various technologies such as Ethernet, Wi-Fi, and Bluetooth to connect devices. The internet itself is a massive global network that connects billions of devices worldwide. Computer networks are essential for businesses, organizations, and individuals to communicate, collaborate, and access information efficiently.

General Description of a Computer Network
A computer network is a collection of interconnected devices that can communicate and share resources with each other. It enables the exchange of data, information, and resources among multiple computers.
Components of a Network:
- Nodes: Devices connected to the network, such as computers, printers, servers, and routers.
- Links: Physical or wireless connections that facilitate data transmission between nodes.
- Network protocols: Rules and standards that govern how data is formatted, transmitted, and received on the network.
- Network infrastructure: Hardware and software that support network operations, such as routers, switches, and firewalls.
Types of Networks:
- Local Area Network (LAN): A small network that connects devices within a limited physical space, such as a home or office.
- Wide Area Network (WAN): A larger network that spans a wider geographical area, such as a city or country.
- Wireless Local Area Network (WLAN): A LAN that connects devices wirelessly using technologies like Wi-Fi or Bluetooth.
- Metropolitan Area Network (MAN): A network that covers a metropolitan area, connecting different LANs within a city or region.
Network Topologies:
- Bus topology: All nodes are connected to a single central cable, called a bus.
- Star topology: Each node is connected to a central switch or hub.
- Ring topology: Nodes are connected in a circular manner, with data flowing in one direction.
- Mesh topology: Nodes are interconnected in a complex, multi-layered structure.
Network Functionalities:
- Data transmission: Facilitates the exchange of data between different devices on the network.
- Resource sharing: Allows users to access and share hardware, software, and peripherals, such as printers and storage devices.
- Communication: Provides channels for real-time communication, such as email, instant messaging, and video conferencing.
- Network management: Enables the administration, monitoring, and troubleshooting of the network.
- Security: Protects the network from unauthorized access, data breaches, and cyber threats.
Computer networks play a crucial role in modern society, enabling collaboration, information dissemination, and business operations. They have transformed the way we communicate, access information, and conduct our daily lives.
