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 all actuality packet-switching had a few contributors. Paul Baran was one of the first people to theorize about packet switching, but never to implement his ideas. Around the same time as Baran, Davies was also a contributor as well as Leonard Kleinrock who worked for DARPA, the precursor to the internet today. These men were all great contributors to packet switching but I find that Kleinrock and Baran were the most influential to the development of packet-switching, Baran being the theorizer and Kleinrock being the modifier and implementer of packet-switching.
Zero Voltage switching is a standard used to describe electrical appliances which turn on or off only when the output voltage is Zero.
Mike Faraday did invent the generator and motor.
A: Assuming the same power output the switching type will be lighter in weight and less bulky.
A chopper to chop DC into AC is an electronic switching. Digital is data bits or machine language whereby a processor can make decisions
What is a 2N2369 transistor.It's an npn switching transistor.
packet switching is use today

Packet 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.
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.
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.
1. circuit switching 2. packet switching
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.
packet switching
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.
packet switching is nothing but the process of converting frames of data into small packets by using some of the algorithms...............
There are three type of switching system such as circuit switching ,packet switching , massage switching.
