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
Why is ATM thee goal for future networking?
The ATM is the goal for future networking because it allows true broadband networking. ATM networking is a cell-switching technology that combines with multiplexing technology.
What is new application enabled by Asynchronous Transfer Mode?
ATM is a fusion between fast switching and synchronous multiplexing technique.
Which WAN technology uses a fixed payload of 48 bytes and is transported across both switched and permanent virtual circuits?
ATM
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 is difference between packet switching frame switching and cell switching?
Packet Switching refers to the transfering of the packet from 1 node to the other. Where as Cell Switching ,means the switching of a cell from 1 network to the other. Pls note that Packet and Cells are 2 different forms. Packet itself has header and pay load and but Packets are variable in size unlike cells which are fix. When packets are switched, the Packet Switch is used and that Switch looks for the next hop in its routing or forwarding table but when a cell is switched, ATM switches are used and the cells actually carry the data and the header and travels from 1 ATM switch to the other. The ATM switches donot use the complex method as Packet Switches use.
What is the difference between ATM and Ethernet?
Here are some paragraphs from the Network + textbook by Tamara Dean (provided through Central Texas College) that explain what Ethernet and ATM are, as well as some differences between Ethernet and the ATM (Asynchronous Transfer Mode) WAN technology. "...Ethernet is a network technology originally developed by Xerox in the 1970s and later improved by Digital Equipment Corporation (DEC), Intel, and Xerox (DIX). This flexible technology can run on a variety of network media and offers excellent throughput at a reasonable cost. Ethernet is, by far, the most popular network technology used on modern LANs. Ethernet has evolved through many variations, and its speed and reliability continue to improve. As a result of this history, it supports many different versions-so many, in fact, that you might find the many variations a little confusing. However, all Ethernet networks have at least one thing in common-their access method, which is known as CSMA/CD (Carrier Sense Multiple Access with Collision Detection)." "All Ethernet networks, independent of their speed or frame type, use an access method called CSMA/CD. To understand Ethernet, you must first understand CSMA/CD." "Like Ethernet, ATM specifies Data Link layer framing techniques. But what set ATM apart from Ethernet are its fixed packet size. In ATM, a packet is called a cell and always consists of 48 bytes of data plus a 5-byte header. This fixed-sized, 53-byte packet allows ATM to provide predictable network performance. However, recall that a smaller packet size requires more overhead. In fact, ATM's smaller packet does decrease its potential throughput, but the efficiency of using cells compensates for that loss. Like X.25 and frame relay, ATM relies on virtual circuits. On an ATM network, switches determine the optimal path before the network transmits data. Because ATM packages data into cells before transmission, each of which travels seperately to its destination, ATM is typically considered a packet-switching technology. At the same time, the use of virtual circuits means that ATM provides the main advantage of circuit switching-that is, a point-to-point connection that remains reliably available to the transmission until it completes, making ATM a connection-oriented technology." I hope this sheds some light on Ethernet and ATM for you.
