WHAT IS THE PURPOSE OF IC 4027 IN SWITCHING CIRCUIT
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.
for switching and protect the circuit in case of fault.
False, the internet uses packet switching while telephones use circuit switching.
No, Ethernet is packet switched.
A circuit switching network physically changes the connection before it sends a message. This would be like the old pulse phone relay system. When you spun the dial on your phone for each number, there would be a switch that would physically move at the other end of the line. Each number switched you to a different set of switches which would in turn combine to make a physical route to your destination. A message switching network is what modern phone systems and computers use to communicate. Most computers use a "Store and Forward" type of switching. Once a network switch receives a message, it stores the entire message in memory, then sends it towards its destination. With message switching, there is no physical switching of the wires. All wires are connected to a processor which determines how to handle the message. For a good explanation of message switching and how packets work on the internet, watch the free movie "Warriors of the Net" from the website below. http://www.warriorsofthe.net/movie.html
There are three (3) ways to do switching: circuit switching, message switching, and packet switching. A network may employ 2 of these (message switching and packet switching) to send and receive data.
ATM use cell switching. it use a 52 by long packet where 48 byte is data and 4 byte is header.
ngn use an ip as a transport unlike in analog switching, it uses packet switching
