1. Cost (Open Source vs Closed Source)

1.1. Nearly all open source OS/Programs are free of cost. People only donate voluntarily. A single installation and it can be used in as many computer as you what.

1.2. Closed Source operating systems are very costly when compared with open source, OS can cost £100 or more per computers. OS/Programs are normally limited to number of installed.

2. Service (Open Source vs Closed Source)

2.1. Open source software relies on loyal and engaged online user community to deliver support via forums and blogs, but this support often fails to deliver the high level of response that many consumers expect.

2.2. Closed Source greatest advantage is support. Ongoing support is a key selling point for users with little technical skills and one of the main reasons people choose closed source over open source.

3. Innovation (Open Source vs Closed Source)

3.1. Open source software provides a large amount of flexibility and freedom to change the software without restrictions. However, this innovation may not be passed onto all users and it is debated whether customised. Changes to original code limits future support and growth of software.

3.2. Closed Source doesn't have the unrestricted flexibility of open source; however, this restriction ensures user security and reliability of close source software that is fully tested and offered to all users.

4. Usability (Open Source vs Closed Source)

4.1. Open source software generally not reviewed by usability experts and caters to developers rather than vast majority of users. User guides are not required, so this is sometimes ignored. Manuals which are written are often hard to follow. Major criticism of open source.

4.2. Closed source software, usability is a high selling point, due to expert usability testing for more targeted audience. User manuals provide for immediate reference and quick training, while support services help to maximise use of software.

5. Security

5.1. Closed source have the resources to respond rapidly to severe security problems in their software. They should be able analyse a problem and have a fix ready in hours.

5.2. When security problems are found in open source software, the fixes are often available within hours. Distributions of the fix is much slower.

6. Open source: Is free and openly available to everyone. People who create open source products, publish the code and allow others to use and modify it.

7. Close Source: This software is legally remains the property of the organisation, groups and or individuals who created it. These organisation who own the software, normally don't release the source code, and need a licence key to use the software.
