| ^ [[dido:public:ra:xapend:xapend.a_glossary:r:router]] | A router is a device like a switch that routes data packets based on their IP addresses. A Router is mainly a [[dido:public:ra:xapend:xapend.a_glossary:n:netlayer|Network Layer]] device. Routers normally connect LANs and WANs together and use a dynamically updated routing table to make decisions regarding data packet routing. Routers divide broadcast domains of hosts connected through it. | | ^ [[dido:public:ra:xapend:xapend.a_glossary:r:router]] | A router is a device like a switch that routes data packets based on their IP addresses.

| - | ^ [[dido:public:ra:xapend:xapend.a_glossary:b:bridge]] | A bridge operates at the data link layer. A bridge is a repeater, with the ability to filter content by reading the MAC addresses of source and destination. It is also used for interconnecting two LANs using the same protocol. It has a single input and single output port, thus making it a 2 port device. | | + | ^ [[dido:public:ra:xapend:xapend.a_glossary:b:bridge]] | A bridge operates at the data link layer.

| ^ [[dido:public:ra:xapend:xapend.a_glossary:g:gateway]] | A gateway, as the name suggests, is a passage to connect two networks together that may work in accordance with different networking models. A gateway basically functions as a messenger agent that takes data from one system, interprets it, and transfers it to another system. Gateways are also called protocol converters and can operate at any network layer. Gateways are generally more complex than a switch or router. | | ^ [[dido:public:ra:xapend:xapend.a_glossary:g:gateway]] | A gateway, as the name suggests, is a passage to connect two networks together that may work in accordance with different networking models.
