What is the importance of data link layer in OSI model?

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 purpose of data link layer in TCP IP reference model?

The data-link layer identifies the network protocol type of the packet, in this instance TCP/IP. The data-link layer also provides error control and “framing.” Examples of data-link layer protocols are Ethernet IEEE 802.2 framing and Point-to-Point Protocol (PPP) framing.

What does the data link layer specify in reference to the OSI model?

Data-link layer of the OSI model specifies Data link procedures that provide for the exchange of data via frames that can be sent and received.

What is the major role of data link layer in OSI model Mcq?

Data link layer mainly deals with framing, error control and flow control. Data link layer is the layer where the packets are encapsulated into frames. Explanation: The logical link control is a sublayer of data link layer whose main function is to manage traffic, flow and error control.

What is the role of the data link layer in the TCP IP model Mcq?

The Data-link layer divides the stream of bits received from the network layer into manageable units called frames. It adds a header to the frame to define the sender and receiver of the frame. It provides a flow and error control mechanism.

What is the role of data link and network layer in TCP IP protocol stack?

The data link layer provides the functional and procedural means to transfer data between network entities and may also provide the means to detect and possibly correct errors that can occur in the physical layer. Examples of data link protocols are Ethernet, Point-to-Point Protocol (PPP), HDLC and ADCCP.

What is a function of the data link layer Cisco?

The data link layer is responsible for network interface card (NIC) to network interface card communications. The data link layer does the following: Enables upper layers to access the media. The upper layer protocol is completely unaware of the type of media that is used to forward the data.

Which among the following represents the functions of data link layer?

Data link layer hides the details of underlying hardware and represents itself to upper layer as the medium to communicate. Data link layer is responsible for converting data stream to signals bit by bit and to send that over the underlying hardware.

Which one of the following is the important protocol used by the data link layer?

The Data Link Layer protocols are Ethernet, token ring, FDDI and PPP. An important characteristic of a Data Link Layer is that datagram can be handled by different link layer protocols on different links in a path.

What is network link?

A link (or edge) of a network (or graph) is one of the connections between the nodes (or vertices) of the network. Links can be directed, meaning they point from one node to the next, as illustrated by the arrows in the first figure below. For more information about network links, see the network introduction.

What is the data link?

A data link is the means of connecting one location to another for the purpose of transmitting and receiving digital information (data communication). These are governed by a link protocol enabling digital data to be transferred from a data source to a data sink.
