5.10 Ethical and Social Implications of Computing Systems

KEY LEARNING OBJECTIVE

Explain the ethical and social implications of computing systems.

Components of Ethical Implications:

  1. Legal issues and intellectual property are big concerns in program creation. Licensing open source software is a big issue, as it dictates how programmers need to comply with terms and how software can be distributed and used.

  2. Data privacy is also a big issue. There are many data protection laws that programmers need to ensure that their code complies with, especially if their program works with data collection and processing.

Components of Social Implications:

  1. There can be harmful impacts from software - malicious software can pose significant security risks.

  2. Software has transformed how people communicate, access information, and interact with each other. Social media platforms, for example, have changed the way society discusses issues, while algorithms can create filter bubbles that limit exposure to diverse opinions.
