Network Terminology
Some general concepts need to be explained:
- Computer networks can be circuit switched or packet switched.
The internet is mainly packet switched, and this is our focus.
- Within packet switched networks, we can still have
two analogous forms of communications:
connection-oriented (virtual circuit) or
connectionless (datagram).
- TCP/IP is an example of the former.
UDP/IP is an example of the latter.
- An everyday example of these two forms of communications
are telephones (circuit switched or connection-oriented)
and postal service (packet switched or connectionless).
