Connection Oriented
In circuit switching, a connection is established between two network nodes before they begin transmitting data.
Message Switching
A hardware connection means a physical link established between devices.
Circut Switching
Circuit switching
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.
The main difference in different switching techniques are:Circuit switchinginvolves setting up a series of intermediate nodes, in order to propagate the sending node's data to the receiving node. In such a situation, the communication line can be likened to a dedicated communication pipe.In circuit switching a session needs to be established between the PC's for communication which is not in the case of packet based switching, where different packets may take different routes to reach the destination and will be assembled to get the original message.Circuit switching is used in Telephone networks where as packet switching is used in TCP/ IP and the internet.Message switchinginvolves transmitting the message sequentially from one node to another. Each node waits until it has received the entire message before sending it to the next node.Packet switchinginvolves splitting information into data packets, transmitted separately by intermediate nodes and reassembled when they reach the final recipient.It is a new technology and economic than the circuit switching approach. It is usually a connection less service.Rate This Answer
Dedicated
Primary attachment
It is established after the 3-way handshake is complete and the channel is open between a sender and a receiver.
Well what is the answer!
A short curcuit is a low-resistance connection established by accident or intention between two points in an electric circuit.
