Mark Scheme
Question 1 (a)
Source code not made available / only compiled code is published
Licence restricts the copying / modifying / distribution of the software
The mention of a licence is not sufficient. Candidate should state that the licence restricts copying / modifying / distributing.
"Closed source" is not enough because it just gives an alternative term for "proprietary" without a description of what we mean by "closed"
Question 1 (b)
e.g.
Stops competing companies copying their software (or hardware / ebooks)
...and producing similar/better products.
Ensures compatibility (with the e-book reader)...
...as they can ensure that no modifications have been made
(mark points in pairs)
The first mark is for identifying a relevant advantage to the manufacturer, and the second for details expanding this point.
Accept answers about preventing reverse engineering the company's product or piracy of the company's software or e-books (e.g. DRM) as referring to the first set of answers.
Question 2 (a)
1 mark per bullet to max 2
e.g.
Other people can improve on the software / add features / maintain
gain a wider ranger of consumers / users
...therefore gain reputation
use for advertising
...gain income from adverts
Do not award mark simply for definition of what open source software is.
Question 2 (b)
1 mark per bullet to max 2
e.g.
Can sell // receive income
Program can be copyrighted
...retain control over source code / modifications
...retain control over distribution
Do not award mark simply for definition of what proprietary software is.
