∙ 13y agoOSI reference model as defined in ITU-T recommendation x.200(ITU-T as 1994d) is a logical architecture which defines a set of principles including protocol layering, layer service definition ,service primitives and independence. these principles are suitable for the definition of the B-ISDN /atm.
However, not all of these principle have been fully applied in the B-ISDN PRM.

Open Systems Interconnection Basic Reference Model has the following seven layers
1. Application layer,2. Presentation layer,
3. Session layer,
4. Transport layer,
5. Network layer,
6. Datalink layer and
7. Physical layer
Asynchronous Transfer Mode is the most reliable mode of transmission used at present
It has the following layers
1. Network layer
2. Data link layer
3. Physical layer
OSI was used for transmission over unreliable medium while ATM is used for reliable transmission as it employs error detection and correction mechanism

What is difference between ATM and ISDN?
1-ISDN is a circuit switching where as ATM is a packet switching. 2-ISDN is a point to point fixed bandwidth where as ATM is a variable bandwidth. By----- RAHUL SINGH ABES IT GHAZIABAD
On which layer of the OSI model does ATM reside?
Layer 2
What is a context model in software engineering?
context model is used to show the external view of the system e.g In a ATM case ATM is a main system its external views is UI(user interface) Account system(Managing acount detail) database system etcc.............................................................
What is the difference between datagram and packet?
datagram is used in conectionless n/w e.g. UDP Whereas packets used in connection oriented n/w e.g. ATM X.25 tcp
What devices are used in an ATM network?
ATM Devices=======================An ATM network is made up of an ATM switch and ATM endpoints. An ATM switch is responsible for cell transit through an ATM network. The job of an ATM switch is well defined: it accepts the incoming cell from an ATM endpoint or another ATM switch. It then reads and updates the cell-header information and quickly switches the cell to an output interface toward its destination. An ATM endpoint (or end system) contains an ATM network interface adapter. Examples of ATM endpoints are workstations, routers, digital service units (DSUs), LAN switches, and video coder-decoders (CODECs). Figure 20-3 illustrates an ATM network made up of ATM switches and ATM endpoints.Figure 20-3: An ATM network comprises ATM switches and endpoints.http://www.pulsewan.com/data101/images12341.gif An ATM Network consists of an ATM switch and ATM end systems.
How many layers are present in ATM reference model?
4 layers are present in ATM reference modal 1.physical layer 2.ATM layer 3. ATM adaptation layer 4. higher layer
What is the difference between atm and debit card?
difference between debit cards and ATM cards Debit cards, there are points of sale or ATM cards, there are no points of sale
What ATM layer has no equivalent layer in the OSI reference model?
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.
What is the difference between POS and ATM withdrawal?
The difference between POS and ATM withdrawal is where the transaction takes place. A POS withdrawal is typically cash back at a point of sale at a retailer while an ATM withdrawal takes place at an ATM.
Can you locate the ATM transcation location by the reference number given in the ATM slip?
yes

What is the difference between two types of connections PVC and svc used in ATM?
An SVC is an on-demand connection that is dynamically established by end devices through the Network-Network Interface (NNI) signaling method. There must be an ATM switch between the end-devices that dynamically route the call through the ATM cloud A PVC is a circuit that a network operator over an ATM-switched network between a specific source and a specific destination manually provisions
On which layer of the OSI model does ATM reside?
Layer 2
Difference between smart card and ATM?
ATM cards are an application of smart card.ATM cards are either smart card or magnetic strip card.A smart card is a card which have an IC chip to process the data/ Smart card have the capability to process the data.
What is the difference between a promina 800 and an ATM?
Promina 800's have the capability to interface to an ATM network but also can interface with many other divices for example symectric trunks up to 8Mbps IP Trunks up to 16Mbps and T-3 trunks
What is the meaning of ATM on a wristwatch?
"ATM" stands for "atmospheres," and the ATM rating on your wristwatch is the depth before the sea surface at which you can safely wear your watch. Most watches are rated between 1 ATM and 10 ATM. For more information, see the Related Link.
What is the difference between corporate banking and private banking?
Corporate banking is the handling of money between banks and companies. Private banking is where individuals deal directly with banks, engaging in activities such as ATM withdrawals and borrowing loans.
