What else can I help you with?
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 four are WAN data-link layer protocols?
The most common WAN data-link protocols are: 1. HDLC 2. PPP 3. Frame Relay 4. ATM
All bit -oriented data link protocols are based on the High-level Data Link Control protocol?
bit
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.
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.
What is the role of the data link layer protocols in data transmission?
The role is to transfer frames to packets
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.
Which two data link layer protocols are used in packet-switched WAN networks?
Atm frame relay
What are two data link layer protocols are used in packet-switched WAN networks?
atm and frame-relay
What protocols operates in the network osi layer and is able to communicate with the transport osi layer and the data link layer?
TELNET
What two engineering organizations define open standards and protocols that apply to the data link layer?
Two key engineering organizations that define open standards and protocols for the data link layer are the Institute of Electrical and Electronics Engineers (IEEE) and the International Organization for Standardization (ISO). The IEEE is notably responsible for the 802 standards, including Ethernet (IEEE 802.3) and Wi-Fi (IEEE 802.11), which govern data link layer operations. The ISO, through its ISO/IEC 8802 series, also contributes to standardizing protocols related to the data link layer. These organizations ensure interoperability and compatibility across various networking technologies.
Protocols at the blank layer accept frames from the Data Link layer and generate voltage so as to transmit signals?
physical layer.
