What is a LLC and a MAC used for?
Logical Link Control (LLC) sublayer provides the logic for the data link. Thus, it controls the synchronization, flow control, and error checking functions of the data link layer. Media Access Control (MAC) sublayer provides control for accessing the transmission medium.
What does the LLC do networking?
The LLC sublayer provides multiplexing mechanisms that make it possible for several network protocols (e.g. IP, IPX and DECnet) to coexist within a multipoint network and to be transported over the same network medium. It can also provide flow control and automatic repeat request (ARQ) error management mechanisms.
What is the difference between LLC and MAC?
The main functionality of the LLC layer is that it multiplexes the protocols over the MAC layer while sending and de-multiplex the protocols while receiving. This layer controls the flow control. The LLC layer comes above the MAC layer and acts as an interface between the upper layers and the MAC layer.
What is the purpose of the layer 2 LLC sublayer?
What is the purpose of the Layer 2 LLC sublayer? It is used to handle multiplexing, flow and error control, and reliability.
What are the functions of MAC?
Functions performed in the MAC sublayer
- Frame delimiting and recognition.
- Addressing of destination stations (both as individual stations and as groups of stations)
- Conveyance of source-station addressing information.
- Transparent data transfer of LLC PDUs, or of equivalent information in the Ethernet sublayer.
What are the functions of MAC in computer network?
The medium access control (MAC) is a sublayer of the data link layer of the open system interconnections (OSI) reference model for data transmission. It is responsible for flow control and multiplexing for transmission medium. It controls the transmission of data packets via remotely shared channels.
What is a network MAC?
(A network port, also known as a network interface, is a way your computer connects to the internet or a network—such as a modem, Ethernet, or Wi-Fi card.) In many cases, you can just use the default Automatic location without setting up additional locations.
Which two functions or operations are performed by the MAC sublayer choose two?
The two primary functions of the MAC sublayer are to encapsulate the data from the upper layer protocols and to control access to the media.
What is a function of the MAC sublayer choose three?
The MAC (Media Access Control) sublayer is responsible for the placement and retrieval of frames on and off the media. The MAC sublayer is also responsible for adding a header and a trailer to the network layer protocol data unit (PDU).
Which connector is used for LAN or Internet?
An 8-pin/8-position plug or jack is commonly used to connect computers onto Ethernet-based local area networks (LAN). Two wiring schemes–T568A and T568B–are used to terminate the twisted-pair cable onto the connector interface.
