Study Notes
Software Definition and Types
- Software is a set of computer programs consisting of a sequence of short commands called instructions that tell the computer what to do.
- Software can be classified into two forms: ROM (read-only memory) and RAM (random access memory).
Software Producers and Buyers
- A software producer, or developer, creates programs to meet user specifications or solve a specific problem.
- Software buyers obtain finished software from developers to satisfy their needs, basing their decision on developer claims.
Software Standards and Liability
- Software developers must ensure their products meet high quality standards, which are mutually agreed upon criteria and expectations of the buyer.
- Buyers have the right to pursue legal action if the product does not meet these standards.
Intellectual Property Rights for Software
- Copyright laws protect software, but patents are usually not suitable for software.
- Trademarks are not an effective way to protect computer programs, but can be used for company branding.
- Trade secrets are effective in protecting software concepts.
Software Security
- Computer software stores vital information and security depends on hardware security.
- A security breach is any incident that results in unauthorized access to data, applications, services, networks, or devices.
Risk Assessment and Management
- System managers need to assess potential risks during software design and use phases.
- Risk assessment involves two key components: assessment and control, which must be evaluated and documented.
Glitches, Flaws, and Weaknesses
- Identifying and predicting system vulnerabilities is crucial in assessing risk, but challenging due to advancing technology.
Standards in Software Development
- Software developers must convey high-quality products to buyers.
- Development testing, verification, and validation are crucial in ensuring software quality.
Reliability, Security, and Safety
- Reliability is the probability that software does not encounter an input sequence leading to failure.
- Software security is integral to a computer system and depends on hardware and software components.
- A software system is unsafe if it creates a condition leading to an accident, hazard, or risk.
Quality and Human Factors
- A software product has quality if it maintains excellence in standards, security, safety, and dependability.
- Human factors, such as memory lapses and overconfidence, can contribute to poor software performance.
- The nature of software programming presents billions of possible outcomes, making testing and error-prone.
