TCP Transmission Control Protocol. TCP is the connection-oriented protocol built on
top of Internet Protocol (IP) and is nearly always seen in the combination TCP/IP
(TCP over IP). It adds reliable communication and flow-control and provides
full-duplex, process-to-process connections. Defined in RFC793.
TFTP Trivial File Transfer Protocol. A simple file transfer protocol used for many pur-
poses including downloading to diskless workstations.
UART Universal Asynchronous Receiver-Transmitter. A computer component (chip)
that handles asynchronous serial communication.
UDP User Datagram Protocol. A connectionless protocol that, like TCP, runs on top
of an IP network. Unlike TCP, UDP provides no error recovery services, offering
instead, a direct way to send and receive datagrams over an IP network.
URL Uniform Resource Locator. The global address of documents and other resources
on the global Internet.
VPN Virtual Private Network. A VPN uses a public telecommunication infrastructure,
such as the Internet, to provide remote offices or individual users with secure
access to their organizations’ networks. VPN maintains privacy through security
procedures and tunneling protocols.
