1. circuit switching 2. packet switching
ATM use cell switching. it use a 52 by long packet where 48 byte is data and 4 byte is header.
packet switching can be considered an improvement over message switching.Similar to message switching,packet switching forwards data on first come first serve basis between nodes and no dedication connection is made (as it is done in circuit switching). But unlike message switching,packet switching puts an upper limit on the maximum size of the packet.If the packet size is greater than the maximum,it is segmented and then transmitted.Each segment has separate header which increases the overhead. But it reduces the average delays.Also in case of packet switching data is not stored for later transmission to a currently busy or inactive terminal.It just takes care of data transmission between nodes
Packet Switching =)

packet switching circuit switching message switching
Packet Switching - Computer Communications (Digital)Circuit Switching was used for old fashioned telephony. At present, many companies use VOIP (Packet Switching) for voice communications.
telephone system uses packet switching because packet switching is reiable. In a packet switching when a packet(some part of total information) is lost then the packet can be retransmitted. But in case of circuit switching if any part of data is lost anytime then total data will be retransmitted. Again circuit swithing is more speedy with compare to packet switching.In order to increase the bit rate (more speed) circuit switch is prefered in Internet.

Circuit switching and Packet switching are used in Telephony. Circuit switching is used in voice communication and packet switching is used in transmission of data packets to provide internet connection.
False, the internet uses packet switching while telephones use circuit switching.
There are three type of switching system such as circuit switching ,packet switching , massage switching.
In circuit switching there is also some required overhead; the overhead in packet switching is usually a small percentage of the total traffic; and in any case, the benefits of packet switching far outweigh any disadvantage of some minor overhead.
Circuit switching.
No, Ethernet is packet switched.
1. Using an idle line to transfer data. 2.The constant transmission date rate. 3.Lose or block of data.
are the standard for the Internet,
