Multiprotocol label switching (MPLS) is a routing technique that uses labels to direct data between different locations over a WAN.These are often used for high-speed data transfer to remote areas. Leased lines offer a dedicated point-to-point connection between two locations.For example, here are different types of WAN connections: A variety of telecommunications links are used to connect devices over a larger geographical area. In contrast, WAN connections are often virtual connections over the public internet. These connections allow for fast communication between devices within a confined geographical area. In LANs, connections between devices are physical-such as through ethernet cables or wireless access points. Examples include multi-layer switches, routers, and technology-specific devices such as frame-relay switches and asynchronous transfer mode (ATM). To do this, they examine the addresses of incoming data packets and forward the packets to the appropriate destination networks. Layer 3 devices route data between different network segments. WANs use DCE from OSI layers 1, 2, and 3. Layer 2 devices, such as switches and bridges, establish and maintain communication between devices on the same network segment. For example, they may convert digital signals into analog signals for transmission over a physical medium. Layer 1 devices, such as hubs and repeaters, physically transmit data over the network. LANs use data communication equipment (DCE) from OSI layers 1 and 2. The layers identify different steps in network communication and various tasks that network components perform to make the exchange happen. The Open Systems Interconnection (OSI) model defines a layered structure of how computers exchange data on a network. Here are other key differences between WANs and LANs. A WAN is a network that connects multiple LANs over a long distance to allow devices to communicate over a wide area. However, a WAN can be made up of multiple interconnected LANs. If you implement strong security measures, both WANs and LANs can provide a secure environment for your users to communicate and share data.įundamentally, both local area networks (LANs) and wide area networks (WANs) connect several devices. Security measures prevent unauthorized access to the network and protect sensitive data during transmission. ![]() You can secure both LANs and WANs by using various methods such as firewalls, encryption, and access control. ![]() There are also other protocols for different types of communication, like the User Datagram Protocol (UDP) and the Internet Control Message Protocol (ICMP). These devices help networks direct traffic and deliver data to the correct destinations.Īdditionally, both LANs and WANs use sets of rules called communication protocols to manage data transmission between connected devices. LANs and WANs both use DCE network devices.

Wired connections use ethernet cables made of coaxial, fiber-optic, or twisted-pair technology. DCE includes things like modems, hubs, or switches, while DTE may be something like two or more computers and printers.Ī link is the transmission media that connects two nodes. ![]() They require two or more nodes to create a computer network.Ī network node may be data communication equipment (DCE) or data terminal equipment (DTE). LANs and WANs are both computer networks made up of nodes and links. Here are other things they have in common. Local area networks (LANs) and wide area networks (WANs) connect computers and peripheral devices so that network users can share data and resources.
