What are the main types of networks in network architecture?

The main types of networks in network architecture are Local Area Networks (LAN), Wide Area Networks (WAN), and Wireless Networks. Each of these categories serves distinct purposes within the broader landscape of networking.

Local Area Networks (LAN) are designed for small geographic areas, such as a single building or campus. They facilitate fast data transfer and allow devices within close proximity to connect and communicate efficiently.

Wide Area Networks (WAN), on the other hand, cover larger geographic areas that can connect multiple LANs across cities, countries, or even globally. WANs often utilize leased telecommunication lines and are crucial for long-distance communication between different sites of an organization.

Wireless Networks provide connectivity without the need for physical cables, using radio waves to transmit data. This technology supports mobility and the convenience of connecting multiple devices in environments where wiring might be impractical.

These three categories comprehensively define the foundational structure of network architecture, focusing on their geographical scope and mode of connection, which helps organizations design their network infrastructures effectively.
