storage area network
A high-performance data communications environment that interconnects computing
and storage resources so that the resources can be effectively shared and consolidated.
subnet mask
Used by a computer to determine whether another computer with which it needs to
communicate is located on a local or remote network. The network mask depends upon
the class of networks to which the computer is connecting. The mask indicates which
digits to look at in a longer network address and allows the router to avoid handling the
entire address. Subnet masking allows routers to move the packets more quickly.
Typically, a subnet may represent all the machines at one geographic location, in one
building, or on the same local area network.
