"system software" and "application software." System software is made up of

control programs such as the operating system and database management sys-

tem (DBMS). Application software is any program that processes data for the

user.

A common misconception is that software is data. It is not. Software tells the

hardware how to process the data.

SSID (Service Set IDentifier) - A unique name shared among all points in a

wireless network. The SSID must be identical for each point in the wireless net-

work and is case-sensitive.

Subnet Mask - The method used for splitting IP networks into a series of sub-

groups, or subnets. The mask is a binary pattern that is matched up with the IP

address to turn part of the host ID address field into a field for subnets.

Switch - 1. A data switch connects computing devices to host computers,

allowing a large number of devices to share a limited number of ports. 2. A

device for making, breaking, or changing the connections in an electrical cir-

cuit.

Topology - A network's topology is a logical characterization of how the

devices on the network are connected and the distances between them. The

most common network devices include hubs, switches, routers, and gateways.

Most large networks contain several levels of interconnection, the most impor-

tant of which include edge connections, backbone connections, and wide-area

connections.

Upgrade - To replace existing software or firmware with a newer version.

Upload - To transmit a file over a network. In a communications session,

upload means transmit, download means receive.

WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-

bit or 128-bit shared key algorithm, as described in the IEEE 802.11 standard.

WLAN (Wireless Local Area Network) - A group of computers and associat-

ed devices that communicate with each other wirelessly.
