#X text 11 66 There are two main protocols for transmitting data over
networks: TCP and UDP.;
#X text 35 119 TCP is the most common \, it stands for Transmission
Control Protocol. Basically \, that means that the protocol manages
the transmission of the data. With TCP \, when you send a packet of
data \, its guaranteed to arrive.;
#X text 34 202 By default \, most networking objects in Pd use TCP:
;
#X obj 54 223 netsend;
#X obj 266 224 netclient;
#X obj 359 224 netserver;
#X text 178 295 UDP stands for User Datagram Protocol. It is a lightweight
\, simple protocol that is meant to be as quick and small as possible.
The downside is that the data packets are not guaranteed to arrive.

#X text 180 409 One advantage to UDP is that you do not need to maintain
a connection to receive data. Whenever you open a UDP port \, you will
start receiving data.;
