How does the data link layer interact with the network layer?

Data-link layer takes packets from Network Layer and encapsulates them into Frames. Then, it sends each frame bit-by-bit on the hardware. At receiver’ end, data link layer picks up signals from hardware and assembles them into frames.

Why does the data link layer need to communicate with the network layer during the process of communication?

The data link layer is responsible for multiplexing data streams, data frame detection, medium access, and error control. It ensures reliable point-to-point and point-to-multipoint connections in a communication network.

What is the role of network and data link layer in the OSI network model?

The data link layer is the second layer in the OSI Model. The three main functions of the data link layer are to deal with transmission errors, regulate the flow of data, and provide a well-defined interface to the network layer. The protocols are the rules required to pass data successfully to the next layer.

Which network works with data link layer?

Network devices that operate at this layer include Layer 2 switches (switching hubs) and bridges. The data link layer is divided into two sublayers: Logical Link Control (LLC) sublayer provides the logic for the data link.

Which feature does the data link layer and Transport Layer have in common?

Features they have in common: Both layers can provide recovery from transmission errors. Both layers can provide flow control. Both layers can support multiplexing.

Which layer links the network support layers and user support layers?

Which layer is used to link the network support layers and user support layers? Explanation: Physical, data link and network layers are network support layers and session, presentation and application layers are user support layers. The transport layer links these layers by segmenting and rearranging the data.

What are the responsibilities of the network layer in the Internet model?

Network layer is the third layer in the OSI model of computer networks….Features :

• Main responsibility of Network layer is to carry the data packets from the source to the destination without changing or using it.
• If the packets are too large for delivery, they are fragmented i.e., broken down into smaller packets.

Can two hosts in two different networks have the same link layer address explain?

But the network layer systems perform two different networks. Can two hosts in two different networks have the same link-layer address? Explain. Yes, they can, because link-layer address local.
