B-21

an 802.1Q-compliant switch or router. Devices recognizing 802.1Q-tagged frames maintain appropriate 
tables to track VLANs. The first three bits of the 802.1Q tag are used by 802.1P to establish priority for the 
packet.

VRRP specifies an election protocol that dynamically assigns responsibility for a virtual router to one of the 
VRRP routers on a LAN. The VRRP router controlling the IP address(es) associated with a virtual router is 
called the Master, and forwards packets sent to these IP addresses. The election process provides dynamic 
fail-over in the forwarding responsibility should the Master become unavailable. This allows any of the 
virtual router IP addresses on the LAN to be used as the default first hop router by end-hosts. The advantage 
gained from using VRRP is a higher availability default path without requiring configuration of dynamic 
routing or router discovery protocols on every end-host.

Also known as World-Wide Web (WWW) or W3. An Internet client-server system to distribute information, 
based upon the hypertext transfer protocol (HTTP).

A WAN is a computer network that spans a relatively large geographical area. Typically, a WAN consists of 
two or more local-area networks (LANs).

WINS. Windows Internet Naming Service is a server process for resolving Windows-based computer names 
to IP addresses. 
If a remote network contains a WINS server, your Windows PCs can gather information from that WINS 
server about its local hosts. This allows your PCs to browse that remote network using the Windows 
Network Neighborhood feature.
