ATM consists of 3 layers AAL (adoption layer) ATM layer (similar to DataLink layer) and Physical layer. AAL layer has no equivalent in the OSI model.
4 layers are present in ATM reference modal 1.physical layer 2.ATM layer 3. ATM adaptation layer 4. higher layer
Layer 2
osi modal is deovaped by iso company it has 7 layers but ATM modal has a 4 layers osi modal have a physical layer,datalink layer,network layer, trasport layer, session layer, perastion layer, application layer, but
none of the above
yes
This is equivalent to 0.2 atm. (152 mmHg)*(1 atm)/(760 mmHg)=0.2atm
Yes, True
Which? Where are the Options?WAN Technologies operate & involve Layer1, Layer2 & Layer3 of OSI Model. Example of WAN Technology Protocols are Frame Relay, ATM & X.25 protocols.
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.

All unregistered ATM cards start off with a default password of the decimal equivalent of the hex string A09G.
