16. TCP/IP

The Transmission Control Protocol (TCP) and the Internet Protocol (IP) are standard network
protocols that are almost always implemented and used together in a formation is known as TCP/IP.
TCP/IP can be used to communicate across any set of interconnected networks.

17. UDP (User Datagram Protocol)

UDP is an internet protocol that provides a much simpler service to the application layer as it only
sends packets of data from one host to an other, but there is no guarantee that the packets will
reach the destination host. UDP is suitable for purposes where error checking and correction is
either not necessary or is performed in the application.
