User CALs & Device CALs Explained
A CAL (Client Access License) is a type of software license distributed by Microsoft to legally allow clients to connect to its server software. Typically, most Microsoft server software come bundled with 5 CALS, which only allows 5 clients to access the server. If you wish to license more users you will need to buy the CAL Add-On packs.
A Device CAL - this permits one device (used by any number of users) to access the server. Device CALs can be used in companies where multiple employees use the same computer to access their server. This is most economic for an organization with multiple users for one device, such as shift workers.
A User CAL - this permits one user using any device to gain access to the server. This is most economic for an organization with many roaming employees that need access to the network from unknown devices and/or employees who access the network via multiple devices – such as administrators.
Processor - Some Microsoft server products can be licensed Per Processor which eliminates the need for buying extra CALs. Under the Per Processor model, you acquire a Processor License for each processor in the server on which the software is running. The benefit of this license is that it allows access for an unlimited number of users to connect to the server.
OEM – OEM (Original Equipment Manufacturer) software can only be sold to system builders who then bundle the software onto newly built computers; it is not for general resale. When you buy a new PC from a high street vendor, it is highly likely the copy of Windows Vista installed is an OEM version. OEM usually comes in a simple sleeve with no packaging, unlike the retail editions which are boxed and come with various documentation and manuals. At Checkout Software.com we do not sell OEM software.
Volume - For larger organisations needing more than five licenses, many publishers have Volume License Programs. The pricing for this type of license is set by the publisher which means that it tends to be more expensive than the price of the software available on our website.
Academic, Educational & Student Software
Many publishers offer a range of software which is priced cheaper than their commercial counterparts as a concession for the following types of users:
- Educational Institutions
- Teachers, Faculty and Staff
- Public Libraries or Museums
The examples above are the most common criteria met for the purchase of these licenses but to check if you are eligible please check with the manufacturer first.
Please Note: If you are to use the software within a commercial business environment you cannot purchase these licenses.
