VoIP Voice Over Internet Protocol: VoIP is based on the principal of
transmitting digitized voice packets over networks. Basically, VoIP
consists of converting voice signals into streams of digital packets
and sending those packets of data through an IP-constructed
network environment. VoIP can work in both LAN (local area
network) and WAN (wide area network) environments for
intranetworking or internetworking communication between VoIP
channel users. Routers and switches and other special compression
protocols direct the packetized voice data to their destination IP
address. VoIP can be less expensive than voice transmission using
standard analog packets over POTS (Plain Old Telephone Service).
It allows telephone calls, faxes, or overhead paging to be transported
over an existing IP data network topology.
VPN Virtual Private Network(VPN) is a virtual created sub-network based
on a public real network. A type of technology designed to increase
the security of information transferred over the Internet. VPN can
work with either wired or wireless networks, as well as with dial-up
connections over POTS. VPN creates a private encrypted tunnel
from the end user's computer, through the local wireless network,
through the Internet, all the way to the corporate servers and
database.
WAN Wide Area Network: For global or long distance networking access
thru the support of telecommunication devices. A communication
system of connecting PCs and other computing devices across a
large local, regional, national or international geographic area. Also
used to distinguish between phone-based data networks and Wi-Fi.
Phone networks are considered WANs and Wi-Fi networks are
considered Wireless Local Area Networks (WLANs).
WLAN Also referred to as LAN. A type of local-area network that uses high-
frequency radio waves rather than wires to communicate between
nodes.
