A device capable of more than bridging is known as a multilayer switch. A layer 2 network device is a multiport device that uses hardware addresses (MAC addresses) to process and forward data at the data link layer (layer 2). A switch operating as a network bridge may interconnect otherwise separate layer 2 networks.
In data communication, a physical network node may either be data communication equipment (such as a modem, hub, bridge or switch) or data terminal equipment (such as a digital telephone handset, a printer or a host computer). A passive distribution point such as a distribution frame or patch panel is not a node.
A typical home or small office router showing the ADSL telephone line and Ethernet network cable connections. A router is an internetworking device that forwards packets between networks by processing the addressing or routing information included in the packet. The routing information is often processed in conjunction with the routing table. A ...
A high-level overview of network bridging, using the ISO/OSI layers and terminology. A network bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments.
Therefore, a compromise between a hub and a switch was developed, known as a dual-speed hub. These devices make use of an internal two-port switch, bridging the 10 Mbit/s and 100 Mbit/s segments. When a network device becomes active on any of the physical ports, the device attaches it to either the 10 Mbit/s segment or the 100 Mbit/s segment ...
The hub manages and controls all functions of the network. It also acts as a repeater for the data flow. In a typical network the hub can be a network switch, ethernet hub, wireless access point or a router. The star topology reduces the impact of a transmission line failure by independently connecting each host to the hub.
The rules only apply to shared-medium 10 Mbit/s Ethernet segments connected by repeaters or repeater hubs (collisions domains) and FOIRL links. The rules do not apply to switched Ethernet because each port on a switch constitutes a separate collision domain. With mixed repeated and switched networks, the rule's scope ends at a switched port.
A network operating system (NOS) is a specialized operating system for a network device such as a router, switch or firewall.. Historically operating systems with networking capabilities were described as network operating systems, because they allowed personal computers (PCs) to participate in computer networks and shared file and printer access within a local area network (LAN).
