There are five application software categories you need to know:
​
-
Open
-
Closed
-
Shareware
-
Freeware
-
Embedded
Open Software
Open (usually known as open-source) software is developed to be freely accessible and allow users to view, modify and distribute the source code. Its purpose is to promote collaboration and customisation when developing software.
Closed Software
Closed (or closed-source or proprietary) software is developed and distributed by a company or individual who owns the source code. The purpose is to maintain control, generate profit and ensure a consistent user experience.
Shareware
Shareware is closed software that is distributed for free on a trial basis, often with limited features or time restrictions. The purpose is to let users try before they buy, encouraging them to later purchase the full version.
Freeware
Freeware is closed software that is completely free to use, usually without restrictions like time limits or limited features, but still owned by a developer or company. The purpose is to provide software for free while retaining control over its code and distribution.
Embedded Software
Embedded software is designed to run on specific hardware and perform dedicated tasks. It is usually built into devices that are not traditional computers (like washing machines or microwaves), allowing those devices to function efficiently and potentially automatically.
For each software category you need to know:
​
-
Its purpose and common characteristics.
-
The types of devices the software may be used on.
-
The advantages and disadvantages of using the software.
-
How client requirements affect the selection of that software.
