what is one main characteristic of the data link layer?
What is one main characteristic of the data link layer? · It generates the electrical or optical signals that represent the 1 and 0 on the media.
What are two characteristics of the data link layer?
Data link layer has two sub-layers: Logical Link Control: It deals with protocols, flow-control, and error control. Media Access Control: It deals with actual control of media.
What are the main functions of data link layer?
2 Data Link Layer. 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 are the 3 parts of data link layer?
A data link layer frame has the following parts: Frame Header: It contains the source and the destination addresses of the frame and the control bytes. Payload field: It contains the message to be delivered. Trailer: It contains the error detection and error correction bits.Jul 30, 2019
What are the features of data link layer and its sub layers?
The data link layer is an interface between the network and physical layer. It is further subdivided into two protocol sublayers: medium access control (MAC) and logical link control (LLC).
What is one main characteristics of a data link layer?
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 are the two 2 basic services of the data link layer?
The Data Link layer performs two basic services: Allows the upper layers to access the media using techniques such as framing. Controls how data is placed onto the media and is received from the media using techniques such as media access control and error detection.
What are the two responsibilities of data link layer?
2 Data Link Layer. 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 are two characteristics of the data link layer?
Data link layer has two sub-layers: Logical Link Control: It deals with protocols, flow-control, and error control. Media Access Control: It deals with actual control of media.
What is the main function of data link layer?
2 Data Link Layer. 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 function of the data link layer?
The data-link layer is responsible for transferring messages (or frame) from a given node to all other nodes in the CAN network. This layer handles bit stuffing and checksums for error handling, and after sending a message, waits for acknowledgment from the receivers.
What are two functions supported by a data link layer protocol quizlet?
What is the 2 main function of the data link layer? *It accepts Layer 3 packets and packages them into data units called frames. *It controls media access control and performs error detection.
Which of the following are the services of data link layer quizlet?
Authentication, compression, and multilink (the use of multiple physical connections).
What is a function of the data link layer 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 a function of the data link layer quizlet?
The primary functions of the data link layer are addressing over a single link and error-detection.
