Router
An intelligent device that sits between an office's local area
network and the Internet. A router redirects incoming traffic from the
Internet to the proper computers on the network, and also concentrates
outgoing traffic and sends it out to the Internet. Most routers will
contain a basic firewall to provide some security.

UPS (Uninterruptible Power Supply)
A device that powers a server, computer, or other hardware from a battery that is constantly recharged with power from the electrical grid. A UPS insulates a server from power glitches and, in the case of a complete power failure, typically supplies enough power for an orderly shutdown.
Virtualization
A server's ability to trick multiple operating systems (or copies of
the same operating system) into believing each one is the sole occupant
of that machine. Typically, one application runs per server to simplify
management, but if the application has marginal use, the server may be
largely wasted. With virtualization, multiple low-use applications can
be on one machine so that fewer servers are required.

WAN (Wide Area Network)

area network inside a building, and may refer to the Internet itself.
