yacklyon・5 minutes read
Networking topologies like bus, ring, star, and mesh connect equipment, with each having specific characteristics and drawbacks. LAN and WAN networks differ in scale and privacy, with WAN networks spanning longer distances and potentially requiring third-party services for connectivity.
Insights
- Physical topologies in networking include bus, ring, star, extended star, hierarchical, and mesh, each with unique connection structures impacting data transmission.
- LAN (local area network) and WAN (wide area network) are distinct network classifications, with LANs being private networks within limited areas while WANs connect LANs over long distances, often requiring third-party service providers for connectivity.

Networking Topologies: Bus, Ring, Star, WAN
- Topologies in networking refer to the way equipment is interconnected, with physical topologies like bus, ring, star, extended star, hierarchical, and mesh. The bus topology involves each computer connected to a cable, with data transmission lost if the cable breaks. Ring topology connects each node to its adjacent, while star topology connects computers to a central point like a switch, with the extended star concept connecting multiple star topologies.
- Mayan topology, connecting a computer to several others, is not widely used due to scalability issues. Hierarchical topology links secondary systems to a main device. Networks are classified into LAN (local area network) and WAN (wide area network), with LAN networks being private and allowing users to create their own network within a limited geographical area. WAN networks interconnect LAN networks over long distances, often requiring a third party service provider for connectivity.
- WAN networks can span cities or neighborhoods, with additional costs for long-distance connections. VPN (virtual private network) services offer a secure way to connect branches over the internet, reducing costs and ensuring encrypted data transmission. Bandwidth, measured in various units, is limited by technology and medium, with associated costs.
