ATM as well as frame relay are switched WANs. Frame relay protocol was designed to replace X.25 . ATM is advantageous as it is a cell network and a cell network uses the cell as a basic unit of data exchange and are small and fixed size block of information .

∙ 11y agoTo tell you in brief, ATM provides QoS(Quality of Service), while X25 and frame Relay dont. ATM has a fixed size frame I.e 53 bytes 5 for the header and remaining 48 for payload,also it is a cell service unlike the other two. hope it helps.

∙ 12y agoThey both operate at layer 2, but the difference is in the way they transfer data.
ATM was designed in the 1980s to deliver five distinct levels of QoS, so users could send traffic with greater or less delay. ATM is a cell service that uses a fixed size cell of 53 bytes, 5 bytes of header and 48 bytes of payload. If the payload was longer than the 48 bytes available, it would be split up and packaged in other cells. This was not true of frame relay, which accommodated frames of widely varying length.
Frame relay, the outgrowth of slower, more careful, error-correcting X.25, is packet technology designed to carry variable-length frames over high-quality connections such as fiber, which was just coming into its own in the early 1990s when frame relay started its heyday.

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
What are the types of network interface card?
Gigabit Ethernet interface Controller interface Serial interface Multilink Group interface MFR (Multilink Frame Relay bundle interface) Dialer interface Loopback interface Tunnel interface ATM interface
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.
DifferenTiate between point-to-point and multipoint connection?
Point-to-point interfaces are used in serial communication. These types of connections are assumed to transmit solely to the station at the opposite end. The examples of Point-to-point are EIA/TIA 232, EIA/TIA 449, X.25, Frame Relay, T-carrier, and OC3 - OC192. simply: 1 source port to 1 destination port Point-to-multipoint connects one station to several other stations. Point-to-multipoint are of two types • Point-to-multipoint Non-Broadcast • Point-to-multipoint Broadcast In Point-to-multipoint Non-broadcast, the communication is replicated to all the remote stations. Only specific, selected stations hear the replicated communication. The examples are Frame Relay and ATM. simply: 1 source port to multiple destination ports
Does ATM and frame relay has anything in common?
Both ATM and Frame Relay are ways to connect your local network router to an ISP

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 do you need to combine asynchronous transfer mode services with dsl to provide an alternative to frame relay?
A DSLAM that supports ATM services A DSL endpoint device that supports ATM technology
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.
Which three WAN devices can be found in the cloud?

Which three modules make up the service provider edge functional area?
Frame Relay/ATM/PPP Internet Service Provider PSTN
What are example of transportation technology?
Car, Airplane, train, bus, subway, and helicopter are all examples of transportation technology.
Which four are WAN data-link layer protocols?
The most common WAN data-link protocols are: 1. HDLC 2. PPP 3. Frame Relay 4. ATM
Suppose a Boston company uses frame relay and a New York company uses ATM these companies merge and now want to communicate using virtual private networks vpns the company has decided that its?
Leave both networks as they are and use an MPLS carrier between them
How can you use Frame Relay with DSL-based access while still offering service level agreement guarantees?
By implementing Asynchronous Transfer Mode (ATM) in the DSL access and backbone network
