Differentiate between proprietary software and freeware software. Name two software for each type.
Proprietary software refers to software that has to be purchased from the vendor who holds the copyright of that software. The user must buy the software to use it legally. Two examples of proprietary software are Microsoft Windows and Tally.
Freeware software refers to software that is freely available for use, but the source code may not be available to the users. Two examples of freeware are Skype and Adobe Reader.
The classification of a software as freeware or proprietary depends upon the terms and conditions set by the person or group who has developed and released that software.
Explanation
The textbook clearly distinguishes between the two types of software. Proprietary software requires purchase from the copyright-holding vendor (examples: Microsoft Windows, Tally, Quickheal). Freeware is freely available for use but source code may not be accessible (examples: Skype, Adobe Reader). The answer follows the 3-mark format with proper differentiation and examples from the context.
