InterNetworking Devices – Networking devices connect multiple LAN’s together to extended a network. They act as intermediate agents for transmission of data in the network. These devices include repeaters, Bridges, Routers, Hubs , Etc. They manage networks into multiple sub networks.
InterNetworking Devices
- Repeater is basically a regenerator as it regenrates the signal.
- Repeater and Hub are layer 1 devies and operate at the Physical layer.
- A Multi-Port repeator is known as Hub.
- Hubs are of three types: active hub, passive hub and intelligent hub.
- Bridge and Switch operate at the Data link layer of OSI model.
- Types of bridges are: Transparent, Translation and Source-route.
- A Switch filters and forwards data to the destination.
- A router is an intelligent device which functions at the Network layer.
- Routers are of two types, Static router and Dynamic router.
- Routing protocols use routing algorithms to determine destination ports.
- Routing protocols are two types, interior and exterior.
- Gateway is a networking device which converts only the data format.
- Backbone is a segment that connects other segments
- Multi-protocol routers support more than one communication protocols.
- Brouter provides computational functions of a bridge and a router.
- Layer 3 switch operates at layer 3 .i.e. network layer of the OSI model.
