What functions reside under the data link layer?
The interface between the physical layer and the network link layer.
What layer of the OSI model is designed to perform error detection functions?
Data Link Layer
Which two layers of the OSI model have the same functions as the TCP model network layer?
physical & data link layers
What kind of address scheme is used at data link layer?
Data link layer transforms the physical layer and makes it appear error free. Data link layer is responsible for physical addressing. It has some other functions like error control, flow control and access control.
What are two functions of the data link layer?
What are two functions of the data link layer? (Choose two.) It segments and reorders the data. It exchanges data between programs that are running on the source and destination hosts. ***It controls how data is placed onto the media. It generates signals to represent the bits in each frame. ***It encapsulates each packet with a header and a trailer to transfer it across the local media. ============================ 1. Data Link layer do not reorder data - this is the job of Transport Layer 2. Programs are at Aplication Layer 4. Physical Layer generate signals
Bridge is used in which OSI layer?
Layer 2 (Data Link Layer) http://compnetworking.about.com/cs/internetworking/g/bldef_bridge.htm
How to describe physical layer protocol functions when receiving data?
Detect and accept signals -Pass on to Data Link layer -Set data transmission rate -Monitor data error rates
What WAN technologies operates at Layer 3 of the OSI model?
The X.25 standard specifies protocols at the Physical, Data Link, and Network Layers of the OSI Model.Broadband Cable functions at both the Physical, and Data Link Layers.ISDN functions at the Physical, Data Link, and Transport Layers.DSL, SONET, and T-Carriers function at the Physical Layer.Frame Relay, and ATM function at the Data Link Layer.
What are the three primary functions provided by Layer 2 data encapsulation?
Primary functions provided by Layer 2 data encapsulation include data link layer addressing, and the detection of errors via cyclic redundancy check calculations. An additional function is delimiting groups of bits into frames.
What primary three functions does data link layer encapsulation provide?
* addressing * error detection * frame delimiting
Bits are packaged into frames at which layer of the OSI model?
Data link layer
Which layer is represented by frames?
The data link layer (layer 2) and the physical layer (layer 1) use the constructed frame.
