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.
What encapsulates incoming ethernet or token ring frames the converts them into ATM cells for transmission over an ATM network?
LANE
Where is ATM technology used?
I'm assuming you mean Asynchronous Transfer Mode, not Automatic Teller Machine. It's used by Telcos, often as part of the SONET optical fibre system. Its main features are its 53-byte cell size and its circuit-oriented design which suits the needs of Telecommunications. Although ATM was "very fast" when first introduced, it's been overtaken by Ethernet over fibre in its various forms. Ethernet can now reliably work at tens of gigabits, and ATM is often "packaged" into Ethernet frames for transport.
What is the cell size of ATM?
53 bytes
What size of an ATM card?
An ATM card is approximately the size of a business card or a visiting card. It is made out of plastic and contains a magnetic stripe on the back side of it.
What has the author Ze Xiang Wu written?
Ze Xiang Wu has written: 'Simulation of transport of Ethernet frames over an ATM network'
Different types of switches used in computer networking?
Ethernet switch,cut through,crossbar,cell backbone,store and forward, back presser, atm, LAN
What does the vendor of an ATM machine get out of having an ATM machine?
An ATM owner gets various kinds of benefits by installing an ATM machines within the business premises like reducing credit risks, increase in foot traffic, customer satisfaction etc. Apart from this ATM machines help in creating brand awareness and advertising.
What is the size of an ATM?
about 3 feet in depth 6 feet in height 2 feet in width
What size nut holds on a Mazda tribute engine cover?
8mm And mine are stuck fast atm!
What is network tepologies?
"Network topology" refers to the physical and/or logical layout of the nodes in a computer network. Common network topologies include "bus" (ethernet, a lot of other networking specs) and "ring" (token ring, ATM).
