What are the two types of ownership/ licensing software
Open source software
Proprietary software
What is open source software
Free of copyright and usually available to anyone
Advantages of open source software
- cheap and provides source code so anyone can modify for their own purposes
- can have many authors so programmers can edit and refine it over time
- a modified version known as a derivative must be also made available
Disadvantages of open source software
- no guarantee it works properly as there is no requirement to debug it
- support might not be readily available especially if the program is not in widespread use
Examples of open software
Linux operating system
Firefox web browser
Python programming language
Open office productivity suite
Thunderbird mail client
What is proprietary software
It is copyrighted meaning it can only be obtained by paying for a license
Advantages of proprietary software
- should be free of bugs, if not then updates known as patches are offered free of charge to fix them
- help can be sought from organisation who supplied the software
- Feature updates which extend the software’s facilities are often available, although usually at a cost
- Proprietary software that is in widespread use often has support available from many sources
Disadvantages of proprietary software
- initial or ongoing (subscription) cost
- software cannot be edited to meat the needs of the user (only machine code provided)
- can be limited to a single device or network so without a license, the user cannot redistribute it
Examples of proprietary software
Windows and OS X operating systems
Microsoft office productivity suite
Adobe creative suite productivity software
Logic music creation software
Paid for games for consoles
