What is the responsibility of the MAC sublayer Cisco?

What is the responsibility of the MAC sublayer Cisco?

What is the responsibility of the MAC sublayer? Media Access Control is responsible for the placement of frames on the media and the removal of frames from the media. It controls access to the media. It communicates directly with the physical layer.

Which two functions are performed at the MAC sublayer of the OSI?

Controls the NIC responsible for sending and receiving data on the physical medium. Places information in the frame that identifies which network layer protocol is being used for the frame. Adds Layer 2 control information to network protocol data. Enables IPv4 and IPv6 to utilize the same network interface and media.

What is Ethernet MAC sublayer?

The MAC sublayer acts as an interface between the logical link control (LLC) Ethernet sublayer and Layer 1 (the physical layer). The MAC sublayer emulates a full-duplex logical communication channel in a multipoint network. This channel may provide unicast, multicast, or broadcast communication service.

What are two primary responsibilities of the Ethernet MAC sublayer choose to?

What are two primary responsibilities of the Ethernet MAC sublayer? (Choose two.)

• accessing the media.
• data encapsulation.
• logical addressing.
• error detection.
• frame delimiting.

What is the responsibility of the MAC sublayer quizlet?

The Media Access Control Layer is one of two sublayers that make up the Data Link Layer of the OSI model. The MAC layer is responsible for moving data packets to and from one Network Interface Card (NIC) to another across a shared channel.

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.

Which two functions are performed at the MAC sublayer of the OSI data link layer quizlet?

Which two functions are performed at the MAC sublayer of the OSI data link layer? Implements a trailer to detect transmission errors. / Controls the NIC responsible for sending and receiving data on the physical medium.

Which two functions are performed at the MSC sublayer of the data link layer?

Integrates various physical technologies. Implements a process to delimit fields within a Layer 2 frame. Controls the NIC responsible for sending and receiving data on the physical medium.

What is the function of MAC sublayer in computer networks?

he 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.

How Ethernet is associated with the MAC sublayer?

Classic Ethernet is the original form of Ethernet used primarily in LANs. It provides data rates between 3 to 10 Mbps.It operates both in the physical layer and in the MAC sublayer of the OSI model. In the physical layer, the features of the cables and networks are considered.

What Layer 2 function does a router perform?

Packet switching is a layer 2 function. If a router can packet switch as well as route, it is a layer 2 and layer 3 device. Same thing as a switch that can do routing. Anything upper layer protocol is going to sit on software and hardware that also function at the lower levels, but routing is done at 3.

Which standard specifies the Ethernet MAC sublayer functionality in a computer Nic?

For Ethernet, the IEEE 802.2 standard describes the LLC sublayer functions, and the 802.3 standard describes the MAC sublayer and the Physical layer functions. Logical Link Control handles the communication between the upper layers and the networking software, and the lower layers, typically the hardware.

What is the function of the MAC sublayer?

Explanation: The MAC sublayer is the lower of the two data link sublayers and is closest to the physical layer. 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 are the primary responsibilities of the Ethernet MAC?

MAC provides physical addressing. The BIA (Burn In Address) which is stored in RAM when the computer boots up is added to each frame that is created as the source mac address. But to answer your question, the MAC layer does the following: Data Encapsulation and Media Access Control.

Which is two functions or operations are performed by the Mac?

Explanation: The MAC sublayer is the lower of the two data link sublayers and is closest to the physical layer. 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.

Which is a sublayer of the OSI Reference Model?

Computer Network Computer Engineering MCA 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.
