SSH
– Acronym for
Secure Shell
or
Secure Socket Shell
; is a command interface and protocol for
getting secure access to a remote computer. To ensure this secure access ssh commands are
encrypted and secure in several ways: both ends of the client/server connection are authenticated
using a digital certificate, and passwords are protected by being encrypted.
TCP
– Acronym for
Transmission Control Protocol
. In TCP/IP architecture, the TCP part is the one
that takes care of keeping track of the individual units of data (packets) that a message was divided
into for efficient routing through the Internet. TCP is known as a connection-oriented protocol, which
means that a connection is established and maintained until the message or messages to be
exchanged by the application programs at each end have been exchanged.
UDP
- Acronym for
User Datagram Protocol
. It is a simpler protocol than TCP that corresponds to
the transport layer of the ISO/OSI model. UDP converts the messages generated by the application
into data packets to be sent through IP, but does not check if the messages have been transmitted
correctly or not.
UMTS
– Acronym for
Universal Mobile Telecommunications System.
The first of the third-
generation (3G) cellular networks, UMTS is being designed to offer speeds of at least 144 Kbps to
fast-moving (e.g., vehicle-based) mobile devices, and offer an initial 2 Mbps to campus sites —
designers expect to increase this to 10 Mbps.
VoIP
– Acronym for
Voice over Internet Protocol
. It achieves the voice calls routing over the
Internet or over any network based on the IP protocol, even in the local networks. Two principal
standards are available for the VoIP
WAN
- Acronym for
Wide Area Network
. A system of LANs, connected together. A WAN is a
network that connects computers located in separate areas, (i.e., different buildings, cities, countries).
The Internet is a wide area network.
