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

The LLC sublayer adds a header and a trailer to the data. The LLC sublayer is responsible for the placement and retrieval of frames on and off the media. Explanation: Logical link control is implemented in software and enables the data link layer to communicate with the upper layers of the protocol suite.

Just so, which two functions are performed at the LLC sublayer?

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.

One may also ask, what is a function of the data link layer? The data link layer takes the data bits and “frames,” and creates packets of the data to guarantee reliable transmission. This layer adds source and destination addresses to the data stream as well as information to detect and control transmission errors. The data link layer has two sublayers.

Additionally, which two functions are performed at the LLC sublayer of the OSI data link layer to facilitate Ethernet communication choose two?

(Choose two.) Enables IPv4 and IPv6 to utilize the same network interface and media. Places information in the frame that identifies which network layer protocol is being used for the frame. Integrates various physical technologies.

Which function or operation is performed by the LLC sublayer?

Explanation: The Ethernet LLC sublayer has the responsibility to handle communication between the upper layers and the lower layers of the protocol stack. The LLC is implemented in software and communicates with the upper layers of the application to transition the packet to the lower layers for delivery.

What is a characteristic of the LLC sublayer?

It provides the logical addressing required that identifies the device. It provides delimitation of data according to the physical signaling requirements of the medium.

What is the purpose of the OSI physical layer?

What is the purpose of the OSI physical layer? The physical layer is responsible for transmitting the actual signals across the physical media as bits. Exchanging frames, controlling media access, and performing error detection are all functions of the data link layer.

Which three basic parts are common to all frame types supported by the data link layer?

Although there are many different data link layer protocols that describe data link layer frames, each frame type has three basic parts: Header. Data. Trailer.

What identifier is used at the data link layer to uniquely identify an Ethernet device?

What identifier is used at the data link layer to uniquely identify an Ethernet device? Explanation: Ethernet frames are identified at the data link layer by their MAC addresses, which are unique to each NIC. IP addresses are used at the network layer, and TCP and UDP port numbers are used at the transport layer.

Which scenario describes a function provided by the transport layer?

The transport layer ensures the correct web page is delivered to the correct browser window. A corporate worker is accessing a web server located on a corporate network. The transport layer formats the screen so the web page appears properly no matter what device is being used to view the web site.

What action will occur if a switch receives a frame and does have the source MAC address?

Question: What action will occur if a switch receives a frame and does have the source MAC address in the MAC table? The switch refreshes the timer on that entry. The switch adds it to its MAC address table associated with the port number.

What OSI Physical Layer term describes the measure of the transfer of bits across a medium over a given period of time?

Question: What OSI physical layer term describes the measure of the transfer of bits across a medium over a given period of time? throughput.

What are the five duties of data link layer?

For effective data communication between two directly connected transmitting and receiving stations the data link layer has to carry out a number of specific functions as follows:

• Services provided to the network layer:
• Frame synchronisation:
• Flow control.
• Error control:
• Addressing:
• Control and data on same link:

What are the issues of data link layer?

The data link layer in the OSI (Open System Interconnections) Model, is in between the physical layer and the network layer. This layer converts the raw transmission facility provided by the physical layer to a reliable and error-free link.

What is Mac in data link layer?

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 controls the transmission of data packets via remotely shared channels. It sends data over the network interface card.

Which device is used in data link layer?

Two types of Data Link layer devices are commonly used on networks: bridges and switches. A bridge is an intelligent repeater that is aware of the MAC addresses of the nodes on either side of the bridge and can forward packets accordingly.

What is the difference between data link layer and network layer?

In OSI model Network layer is responsible for 'source-to-destination' delivery of a packet possibly across the multiple networks( links ),whereas the data link layer oversees the delivery of the packets btw 'two' systems on same network.

What is the difference between physical layer and data link layer?

The physical layer describes the way data is actually transmitted on the network medium. The data link layer defines how these streams of bits are put together into manageable chunks of data. Ethernet is the best known implementation of the physical and data link layers.

What happens at the network layer?

Network layer works for the transmission of data from one host to the other located in different networks. It also takes care of packet routing i.e. selection of the shortest path to transmit the packet, from the number of routes available. The sender & receiver's IP address are placed in the header by network layer.

Explanation: Cut-through switching provides lower latency switching for high-performance computing (HPC) applications. The cut-through switching method can make a forwarding decision as soon as it looks up the destination MAC address of the frame.

What addressing information is recorded by a switch?

Explanation:A switch builds a MAC address table by inspecting incoming Layer 2 frames and recording the source MAC address found in the frame header. The discovered and recorded MAC address is then associated with the port used to receive the frame.
