Packet Switching =)
Data transfer will be faster in packet switching providing the setup time in circuit switching is greater than the time required to send a packet. If not, that is setup time in circuit switching takes less time, then circuit switching is quicker.

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
ATM use cell switching. it use a 52 by long packet where 48 byte is data and 4 byte is header.
____ is an updated, digital version of X.25 that also relies on packet switching.
Frame Relay
Packet Switching - Computer Communications (Digital)Circuit Switching was used for old fashioned telephony. At present, many companies use VOIP (Packet Switching) for voice communications.
packet switching is use today
It transmits each packet in a multipacket message independently It supports interoperability between digital devices with different data rates
Packet switching has two advantages: (1) If something goes wrong, only a small piece of data (the packet) has to be resent. (2) Packet switching allows multiplexing - several communications happening at once.Packet switching has two advantages: (1) If something goes wrong, only a small piece of data (the packet) has to be resent.

Paul Baran originally invented the packet switching concept in the early 1960's. Donald Davies also independently invented the idea a few years later. Then, Leonard Kleinrock conducted early research in the related field of digital message switching. He also helped build the ARPANET, the world's first packet switching network.

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.
