What this dot point is asking

OCR wants you to know the main laws that apply to computing and what each one covers, plus the difference between open source and proprietary software licensing. This is recall with application: you must be able to name the Act, say what it protects or makes illegal, and match a scenario to the right law. It is reliably examined on Paper 1.

The Data Protection Act 2018

The everyday relevance is that any organisation holding your details, a school, a shop, a website, must look after that data and use it only for what you agreed to. When an exam scenario involves storing customer or pupil data, this is the Act to cite.

The Computer Misuse Act 1990

The three offences increase in seriousness: simply getting in, getting in to do further harm, then actually altering or destroying data. Match the scenario carefully: guessing a friend's password and reading their messages is the first offence; spreading ransomware that encrypts files is the third.

Software licensing: open source versus proprietary

Try this

Q1. State the law that controls how organisations store and use personal data. [1 mark]

  • Cue. The Data Protection Act 2018.

Q2. State the three offences under the Computer Misuse Act 1990. [3 marks]

  • Cue. Unauthorised access; unauthorised access with intent to commit a further offence; unauthorised modification of data.

Q3. Give one advantage of open source software and one advantage of proprietary software to a user. [2 marks]

  • Cue. Open source: usually free and can be modified to suit the user. Proprietary: official support and regular, tested, reliable updates.

OCR 20214 marksThe Computer Misuse Act 1990 makes certain actions illegal. State the three offences defined by the Act, and for one of them give an example of an action that would break it.
Show worked answer →

Three offences (1 mark each, up to three): unauthorised access to computer material (level 1, the basic offence of hacking into a system you are not allowed to use); unauthorised access with intent to commit a further offence (level 2, accessing a system to steal data, commit fraud or blackmail); and unauthorised modification of computer material (level 3, changing or deleting data without permission, for example planting a virus).

Example (1 mark): for the first offence, guessing or stealing a password to log in to someone else's email account. For the third, deliberately spreading malware that encrypts a hospital's files.

Markers reward the three offences in recognisable form and a matching example; vague answers such as "hacking is illegal" do not name the distinct offences.

OCR 20224 marksExplain the difference between open source and proprietary software, giving one advantage of each to the user.
Show worked answer →

Open source (up to 2): the source code is made freely available and can be viewed, modified and shared, usually free of charge (for example Linux or Firefox). Advantage to the user: it is usually free and can be adapted to their needs, and a community can fix bugs.

Proprietary (up to 2): the source code is kept secret and the software is licensed, not sold, so users may not modify or share it; they pay for a licence (for example Windows or Adobe Photoshop). Advantage to the user: it usually comes with official support, regular tested updates and a polished, reliable product.

Markers reward the source-code distinction (open and editable versus closed and licensed) and a genuine advantage for each, not just "one is free and one costs money".
