Important Information
many virtual servers reside on the same computer, or if one virtual server starts hogging resources, Web pages will be delivered more slowly.
VPI and VCI
A VPI (Virtual Path Identifier) is an
VPN
Short for Virtual Private Network, a network that is constructed by using public wires to connect nodes. For example, there are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

WAN
Short for Wide Area Network. A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more Local Area Networks (LANs). Computers connected to a WAN are often connected through public networks, such as the telephone system.
WEP
Short for Wired Equivalent Privacy, a security protocol for wireless local area networks (WLANs) defined in the 802.11b standard. WEP is designed to provide the same level of security as that of a wired LAN. LANs are inherently more secure than WLANs because LANs are somewhat protected by the physicalities of their structure, having some or all part of the network inside a building that can be protected from unauthorized access. WLANs, which are over radio waves, do not have the same physical structure and therefore are more vulnerable to tampering. WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another.
WLAN
Short for Wireless Local Area Network which is a cellular computer network that transmits and receives data with radio signals instead of wires. Wireless adapter cards used on laptop and desktop systems, support the same protocols as Ethernet adapter cards.
