Layer 3 of the OSI model, known as the Network Layer, is responsible for packet forwarding, including routing through different networks. It manages logical addressing, typically using IP addresses, to ensure that data packets are sent from the source to the destination across multiple hops. Protocols like IP (internet Protocol) operate at this layer, enabling devices to communicate over diverse networks. Additionally, Layer 3 handles traffic control and fragmentation of packets when required.
What else can I help you with?
Switch work in which layer of osi modle?
layer 3 layer 3 Switch/ Bridges / Hubs works at layer 2 as they utilizes MAC address to communicate. However i aggree above stated answer as there are some layer three switches that work at Layer3 i.e. Network Layer. Dhruv
What network component operates at layer 3 of the OSI RMrm and forwards network protocols such as ip toward their destination?
Routers and layer 3 switches work at Layer 3 of OSI model.
Why do you call router as layer three device?
Routers operate in layer 3 because they must use the logical network address to determine which network to route the packet to. Logical addressing is a feature of layer 3, therefore a router is a layer 3 device.
How does network packets work?
On a packet switched network, data travels between layers 1, 2 and 3 of the OSI model using routers (layer 3), switches (layer 2), and media (layer 1).
DCHP work at which layer?
It is work at Network layer.
What osi layer does a router reside in?
All layers - but to the greatest extent, the distinctive work done by the router - specifically, routing packets - corresponds to layer 3.
Amplifier work in which layer in osi layer?
Layer 1 - the physical layer
Which layer does SMTP work at?
Application Layer
Bridges work in which layer in osi layer?
Layer 2 , Data Link Layer
What two things are needed to make TCP IP work with in a layer three segment?
The IP address and the subnet mask are required in layer 3 for routing purposes.
Switch work in which layer of osi model?
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
What is the gateway layer?
Network layer or layer 3
