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.
What else can I help you with?
Which layer does a bridge operate?
Bridge operate on data link layer
At which layer does a WAP operate?
Data Link Layer
What layer of the osi model does a LMI operate at?
Layer 2 - Data Link
What protocols operates in the network osi layer and is able to communicate with the transport osi layer and the data link layer?
TELNET
Does a DSL operate at layer 3 of the osi model?
No. A digital subscriber line (DSL) operates at layer 2 or the Data-link layer.
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
Which layer of the OSI model does ISDN Q921 operate?
data link
Which device operate data link layer?
The Network Interface cards
Protocols at the blank layer accept frames from the Data Link layer and generate voltage so as to transmit signals?
physical layer.
Switches operate at layer and Hubs operate at layer of OSI model?
Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.
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 the role of the data link layer protocols in data transmission?
The role is to transfer frames to packets
