A computer network allows computing devices to share resources by exchanging data through connections between nodes. There are three main types of networks: local area networks (LANs) which span a small area like a building; metropolitan area networks (MANs) which connect multiple LANs across a city; and wide area networks (WANs) which connect smaller networks across large geographical areas. Network interface cards and modems are hardware devices that allow computers to connect to networks by converting digital data for transmission.
Computer networks
There are three main types of computer networks: local area networks (LANs) which connect computers within a single building or small area; wide area networks (WANs) which connect computers over large distances using leased telecommunication circuits; and metropolitan area networks (MANs) which connect users within a region larger than a LAN but smaller than a WAN. LANs are usually confined to a single building, WANs are used by businesses and organizations to relay data worldwide, and MANs interconnect resources in an area like a city.
Networks
A network connects two or more computer systems and can take several forms. A local-area network (LAN) connects computers within close geographic proximity, such as within a building. A wide-area network (WAN) connects computers located farther apart using telephone lines or radio waves. Other types of networks include campus-area networks (CANs) within a limited area like a campus, and home-area networks (HANs) within a private home. Network security provisions and policies are implemented to prevent unauthorized access. Network services provide functions and help networks operate by hosting applications on servers. Nanoscale networks have key components and leverage physical principles at the nanoscale level.

Sarthak Srivastava's class discusses four types of computer networks: local area networks (LANs) which connect buildings near each other, metropolitan area networks (MANs) which connect an entire city, wide area networks (WANs) which connect locations in different cities or countries like the internet, and campus area networks (CANs) which connect local networks within a university.
Lan vs Man
LAN (Local Area Network) is a computer network covering a small geographic area like a home, office, or group of buildings. It connects more than one computer using technologies like Ethernet and Token Ring. Maintenance of a LAN is relatively low cost due to its small area.
WAN (Wide Area Network) connects multiple LANs across a broader area that can span multiple buildings, cities, or countries. The Internet is an example of a worldwide public WAN. Maintaining a WAN is more difficult and costly than a LAN due to its larger geographic coverage. Technologies used include ATM, Frame Relay and X.25 to connect over longer distances.

Computer networking and its different types
Computer networking is the practice of connecting multiple devices to share resources and communicate with each other. It involves the use of various hardware and software components to facilitate data transmission and exchange between computers, servers, routers, switches, and other network devices.At its core, computer networking enables the sharing of information, files, and resources such as printers and internet connections among interconnected devices. This connectivity allows users to collaborate, access remote resources, and communicate in real-time, whether within a local area network (LAN), wide area network (WAN), or the internet.The foundation of computer networking lies in the establishment of protocols and standards that govern how data is transmitted and received across the network. Protocols such as TCP/IP (Transmission Control Protocol/Internet Protocol) define rules for addressing, routing, and error detection to ensure reliable and efficient communication between devices.Networking hardware plays a crucial role in facilitating connectivity and data transmission within a network. Devices such as routers, switches, hubs, and access points serve as the infrastructure that enables devices to connect and communicate with each other. Routers, for example, manage data traffic between different networks, while switches facilitate communication within a single network by directing data packets to their intended destinations.In addition to hardware components, networking relies heavily on software solutions to manage and control network operations. Network operating systems (NOS) provide the necessary software infrastructure for configuring and managing network devices, implementing security measures, and monitoring network performance. Examples of popular NOS include Cisco IOS, Juniper Junos, and Microsoft Windows Server.Security is a critical aspect of computer networking, given the potential risks associated with unauthorized access, data breaches, and cyberattacks. Network security measures such as firewalls, encryption, virtual private networks (VPNs), and intrusion detection systems (IDS) help safeguard network resources and sensitive information from malicious threats.Computer networking encompasses a wide range of technologies and methodologies, including wired and wireless networking, cloud computing, virtualization, and software-defined networking (SDN). Wired networking utilizes physical cables such as Ethernet or fiber optic cables to establish connections between devices, while wireless networking relies on radio waves to transmit data over the air.Cloud computing and virtualization technologies have revolutionized the way networks are deployed and managed, allowing organizations to leverage shared resources and scale their infrastructure dynamically. Software-defined networking (SDN) is another emerging paradigm that centralizes network control and management through software-based controllers, enabling greater flexibility,
LAN's And MAN's
Local area networks (LANs) are privately owned networks within a single building or campus that connect devices like personal computers and workstations. They allow for resource and information sharing between devices. LANs are distinguished by their small size of up to a few kilometers, transmission technologies used, and network topologies. Metropolitan area networks (MANs) cover larger geographical areas like an entire city and provide internet connectivity to multiple LANs. While MANs provide greater access and sharing, they are more costly and difficult to implement than LANs due to requiring more hardware, software, and security measures over a wider area.
