TCP/IP, UDP: Transmission Control Protocol/Internet Protocol (TCP/IP) and
Unreliable Datagram Protocol (UDP). TCP/IP is the standard protocol for data

UDP, on the other hand, is not reliable. They both run on top of the IP (Internet
Protocol), a Network layer protocol.

geographically separate areas (for example, in different buildings, cities, or
countries). The Internet is a WAN.
