Data link control definition - a data link control is a service that ensures reliable network data communication by managing frame error detection and. Start studying data link control chap 7 learn vocabulary, terms, and more with flashcards, games, and other study tools.

This is the mcq in data link control from book the data communications and networking 4th edition by behrouz a forouzan if you are looking for a reviewer in datacom, topic in electronics systems and technologies (communications engineering) this will definitely help you before taking the board exam. Generic data link control environment overview generic data link control (gdlc) defines a generic interface with a common set of commands that allows application and kernel users to control dlc device managers within the operating system.

A high-level data link control (hdlc) is a protocol that is a bit-oriented synchronous data link layer hdlc ensures the error-free transmission of data to the proper destinations and controls the data transmission speed. The data link layer, or layer 2, is the second layer of the seven-layer osi model of computer networking data-link-layer flow control is not used in lan protocols such as ethernet, but in modems and wireless networks media access control (mac) sublayer.

High-level data link control (hdlc) is a bit-oriented code-transparent synchronous data link layer protocol developed by the international organization for standardization (iso) the original iso standards for hdlc are as follows: iso 3309-1979 – frame structure.

There are three types of techniques available which data-link layer may deploy to control the errors by automatic repeat requests (arq): stop-and-wait arq the following transition may occur in stop-and-wait arq.

Data link control

This flow control mechanism forces the sender after transmitting a data frame to stop and wait until the acknowledgement of the data-frame sent is received sliding window in this flow control mechanism, both sender and receiver agree on the number of data-frames after which the acknowledgement should be sent. In the osi networking model, data link control (dlc) is the service provided by the data link layer network interface cards have a dlc address that identifies each card for instance, ethernet and other types of cards have a 48-bit mac address built into the cards' firmware when they are manufactured. Dlc (data link control) is the service provided by the data link layer of function defined in the open systems interconnection (osi) model for network communication the data link layer is responsible for providing reliable data transfer across one physi.

Generic data link control (gdlc) defines a generic interface with a common set of commands that allows application and kernel users to control dlc device managers within the operating system. The ohio state university raj jain 5-9 stop and wait flow control data ack ack data t frame t prop α = t prop t frame = distance/speed of signal frame size /bit rate = distance × bit rate.

Data link control a general overview datalink protocols assume that the connected nodes have some way to transfer frames of data from one to the other, and that the receiver can detect errors when they occur in a frame. Data link control protocols overview flow control space-time diagrams stop and wait flow control utilization: examples efficiency principle sliding window protocols sliding window diagram sliding window example sliding window protocol efficiency effect of window size piggybacking.
