TCP is one of the protocol types, which has a process of a connection. Basically, the TCP
connection has to be one-to-one. The part who tries making a connection is called TCP
Client, and the other part is called TCP Server. On the other hand, UDP has no connection
process, so that each of UDP hosts can transmit and receive data from multiple hosts.
