• Network Hosting A method of delivering applications by installing them in the local network.
• Cloud Hosting A method of delivering applications by hosting them in the cloud.
• Software as a Service (SaaS) A term associated with cloud hosting. SaaS provides users with the applications they need to do their day-to-day work through the cloud.
• One Tier An application architecture model where programs run as standalone applications on a single computer.
• Two Tier An application architecture model with two separate tiers (a client and a server) where applications store and retrieve data from a central repository.
• Three Tier An application architecture model with three separate tiers where an application presents the user interface on a client workstation, data is processed on an application server, and information is retrieved from a database management system on a database server.
• n-Tier An application architecture model where application developers add as many tiers as they need to create the most efficient services and processes on a network.
• Platform Compatibility A concern with using enterprise software in a network with multiple computer platforms and operating systems.
• Proprietary Software Software that isn’t owned but requires the purchase of a license to use the software.
• Personal License A software license given to home and small business customers that allows them to install the software on a limited number of systems.
• Enterprise License A software license, often called a volume license or a site license, that allows the customer to install the software without restriction using the same activation code, typically until a maximum cap is reached.
• Open Source Software Software that can be downloaded, installed, and used without paying a licensing fee. The source code can also be downloaded, modified, and compiled and given to others as long as it is not resold for profit.
• Software Subscription Sometimes called SaaS or on-demand software, software that requires a monthly or annual fee to use the software and receive regular updates.
• Windows Update A feature of the Windows operating system that keeps the operating system up to date.

Topics Discussed:

• What are the advantages and disadvantages of hosting applications on the cloud?
• What are the advantages and disadvantages of software subscription licenses?
• Why is it important to keep system and application software up to date?
