data into small units, called "packets," to be sent to another computer and how the receiving computer reassembles the
packets into a single file. IP determines how the packets are routed across the Internet.

Virtual Local Area Network (VLAN):
A VLAN is a network of computers that behave as if they are connected to the same wire, even though they may be physically
located on different segments of a LAN. VLANs are configured through software rather than hardware, which makes them
extremely flexible. When a computer on a VLAN is physically moved to another location, it can stay on the same VLAN without
any hardware reconfigurations.
Virtual Server:
A virtual server is a device that performs Internet protocol (IP) mapping. IP mapping allows remote client access to your
network via the Internet.
Wide Area Network (WAN):
A WAN is a communications network that uses devices such as telephone lines, satellite dishes, or radio waves to span a
larger geographic area than can be covered by a
LAN.
Wireless Local Area Network (WLAN):
A WLAN is a type of Local Area Network (LAN) that uses high frequency radio waves rather than wires to communicate and
transmit data among the network clients and devices. It is a flexible data communication system implemented as an extension
to, or as an alternative for, a wired LAN. Just like a LAN, the network lets users at that location share files, printers and other
services.
xDSL Modem:
DSL is a type of service that allows people to access the Internet via their telephone lines. This service is typically available via
a telephone company or service provider.
An xDSL connection is a high-speed digital connection to the Internet using standard copper twisted pair telephone wires.
There are several kinds of DSL; the x refers to all of them.
