The difference among different types of switching devices is in the features and the functions that they have. The two main types are packet switching and circuit switching devices.
PSTN stands for Public switched telephone network PSDN stands for Public switched Data network / Packet Switched Data Network. The basic difference between two is the switching technique used. PSTN uses Circuit Switching and PSDN uses Packet Switching
B-ISDN is a circuit switching process. The N-ISDN is a virtual switching process (packets). ISDN stands for Integrated Service Digital Network.
1.circuit switching statically reserves the required bandwidth in advance whereas packet switching acquires & releases it as it is needed. 2.With circuit switching any unsed bandwidth on a allocated circuit is just waisted.with packet switching it may be utilised by other packets . 3.Circuit switching needs to set up an end to end path before any data can be sent. 4.When packet switching is used it is straight forward for router to provide speed and code conversion. 5.In packet switching packet may be delivered in the wrong order. 6Packet carriers usually base theier charge on both the no. of bytes(or packets carried and connect time. 7.with circuit switching, the charge is based on the distance and time only, not the traffic.

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
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.
It is simplest form of switching which have dedicated physical path between sending and receiving. In circuit switching network,a set of switches are connected by physical link. A connection between the two stations is a dedicated path made up of one or more links.
difference between series is one pathway through circuit,difference between parralal is more then one pathway through circuit.
WHAT IS THE PURPOSE OF IC 4027 IN SWITCHING CIRCUIT
circuit 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.
