For labs, a license to base the software from the network is often needed. If software is easy to use, faculty sometimes simply request that their Resource Specialist install the software on the network, so that their students may use it from their dorm rooms or from the public facilities at other times. A network license is also needed in this instance. Other ways of using classware exist, but these are the most common, and will provide some idea of the options. Acquiring Classware Software is offered by vendors through several arrangements.
Some software is only available for purchase at retail prices as individual units.
If you need only to demonstrate the software in class, only a single copy may be needed. Some software is available in volume discounts. This is very valuable when the software is to be installed on multiple machines, as in a lab. Occasionally, software is offered free for general use or specifically for educational environments. Often, this is very simple, home grown, or academic software.
