![]() ![]() ![]() However WANs using public networks can be setup very cheaply using just software (VPN etc). If there is a need to set-up a couple of extra devices on the network, it is not very expensive to do that.įor WANs since networks in remote areas have to be connected the set-up costs are higher. WANs (like the Internet) are not owned by any one organization but rather exist under collective or distributed ownership and management over long distances. Typically owned, controlled, and managed by a single person or organization. ![]() WANs tend to be less fault tolerant as they consist of large number of systems.Įxperiences fewer data transmission errorsĮxperiences more data transmission errors as compared to LAN LANs tend to have fewer problems associated with them, as there are smaller number of systems to deal with. Layers 3 devices Routers, Multi-layer Switches and Technology specific devices like ATM or Frame-relay Switches etc. Layer 2 devices like switches and bridges. ![]() They can also be connected through leased lines or satellites. One LAN can be connected to other LANs over any distance via telephone lines and radio waves.Ĭomputers connected to a wide-area network are often connected through public networks, such as the telephone system. WANs tend to use technologies like MPLS, ATM, Frame Relay and X.25 for connectivity over longer distances Tend to use certain connectivity technologies, primarily Ethernet and Token Ring The network in an office building can be a LAN WANs have a lower data transfer rate compared to LANs. WAN (Wide Area Network) is a computer network that covers a broad area (e.g., any network whose communications links cross metropolitan, regional, or national boundaries over a long distance). LAN (Local Area Network) is a computer network covering a small geographic area, like a home, office, school, or group of buildings. Large geographic areas (e.g., cities, states, nations) Local areas only (e.g., homes, offices, schools) Comparison chart LAN versus WAN comparison chart ![]()
