TCP is a type of protocol, which has a process of connection. The connection has to be
one to one. The part who tries to make the connection is called TCP Client, and the other
part is TCP Server. On the other hand, UDP has no connection process. Because of this,
each of them can be send and receive data from multiple hosts.
Basically, the connection should be established 1 to 1 in TCP. However, EZL-200F can
make 8 channels at a time while using the [multiple connection] option.
