The role is to transfer frames to packets
What else can I help you with?
The data link layer handles transmission errors by requesting damaged frames to be?
Damaged frames are discarded. Retransmission - if needed - is handled by higher-layer protocols, like TCP.
Which layer of the osi model provides the address and routing necessary to ensure that data moves from one system to another?
Network Layer This layer addresses the data. It adds an IP address which allows our data to flow across networks. The protocols involved in this layer are IP and IPX. Data Link Layer This layer provides the functional and procedural means to transfer data. It also corrects any errors that may occur in the Physical layer. The protocols used at this layer are media access control and logical link control.
Elementary data link protocols?
Elementary data link protocols must agree at the most rudimentary level. The data frame must be constructed from this level, and all protocols must agree.
Which layer of the OSI model encapsulates Network layer pockets?
the network layer --> check your question. ^^^^^^^^^^^^^^^^^^^^^^^^^^^ That is totally not the right answer, how about you actually read the book for the course. It is the data link layer that does encapsulation. I agree - its the Data Link Layer which encapsulates the Network layer...NOT the Network Layer.
Bits are packaged into frames at which layer of the OSI model?
Data link layer
Which statement accurately describes a role that is played in establishing a WAN connection?
Data link layer protocols like PPP and HDLC define how data is encapsulated for transmission across a WAN link.
The data link layer handles transmission errors by requesting damaged frames to be?
Damaged frames are discarded. Retransmission - if needed - is handled by higher-layer protocols, like TCP.
What protocols operates in the network osi layer and is able to communicate with the transport osi layer and the data link layer?
TELNET
Which four are WAN data-link layer protocols?
The most common WAN data-link protocols are: 1. HDLC 2. PPP 3. Frame Relay 4. ATM
Protocols at the blank layer accept frames from the Data Link layer and generate voltage so as to transmit signals?
physical layer.
The what layer in the OSI model arranges data into packets whereas the what layer prepares data for physical transmission?
network data-link
Which protocols do not operate at the network layer?
Protocols that do not operate at the network layer include those in the transport layer, such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), which are responsible for end-to-end communication and data flow control. Additionally, application layer protocols like Hypertext Transfer Protocol (HTTP) and File Transfer Protocol (FTP) operate above the network layer to facilitate specific application services. Furthermore, protocols in the data link layer, such as Ethernet and Wi-Fi, manage local network communication and frame delivery.
What do WAN Data link protocols describe?
Here's what you should know: Data link layer protocols must be concerned with the rules for transmitting data across the network media, particularly with encoding and carrying "frames" of data. Although this layer includes providing error detection and notification by adding the Cyclic Redundancy Check (CRC), the Transport Layer is primarily responsible for end-to-end error-free message delivery. WAN Data-Link protocols primarily define how data frames should be packaged for different types of networks. To quote: The data link protocols available for WAN communications define how networks will carry the data frames on a given data link. The data link protocols used for WANs come in three categories: 1. Interface to IBM enterprise data centers: SDLC 2. WAN connections using peer devices: HDLC & PPP 3. Switched or relayed services: X.25/LAPB, Frame Relay, ISDN/LAPD, ATM. Some of these protocols provide functionality as high as in the Network layer of the OSI, and all of these protocols transfer data over a WAN data link.
What is L2 line Layer?
The L2 line layer, also known as the Data Link Layer, is the second layer of the OSI (Open Systems Interconnection) model. It is responsible for node-to-node data transfer, error detection and correction, and framing of data packets for transmission over the physical layer. This layer ensures the integrity of data as it travels across a network and manages access to the physical transmission medium. Protocols such as Ethernet and Wi-Fi operate at this layer, facilitating communication between devices on the same local network.

The protocols used at this layer are media access control and logical link control.
Which protocols operate at the data link layer?
The data link layer, which is the second layer of the OSI model, includes protocols such as Ethernet, Point-to-Point Protocol (PPP), and High-Level Data Link Control (HDLC). Ethernet is widely used for local area networks (LANs), while PPP is commonly used for direct connections between two network nodes. Additionally, protocols like Wi-Fi (IEEE 802.11) also operate at this layer, facilitating wireless communication. These protocols handle framing, addressing, and error detection for data transmitted over physical media.
Suppose transmission channels become virtually error free.Is the data link layer still needed?
The data link layer is still needed for flow control over the transmission channel and for framing the data. In a multiple access medium such as a LAN, the data link layer is required to coordinate access to the shared medium among the multiple users.
