There are two types of switching system, these are as follows:
Circuit Switching:
It is the most familiar technique used to build a communication network. Used in ordinary telephone lines and it allows communications equipment and circuits to be shared among users. Each user has the sole access to a circuit during network use.
Packet Switching:
A network technology that breaks up a message into small packets for transmission, unlike circuit switching, which requires the establishment of a dedicated point to point connections each packet in a packed switched network contains a destination address. Thus all packets in a single message do not have to follow the same path. Packet can arrive out of order. Destination computer reassembles the packets into their proper sequence.
