The main objective of software reverse engineering is to understand and modify existing software. This process involves analyzing and deconstructing software to uncover its design, functionality, and logic, which can be valuable for various purposes, such as maintenance or improvements.

Reliability is the quality attribute that pertains to a system's ability to function correctly even when faced with invalid inputs or stressful environmental conditions. In software engineering, reliability is crucial for ensuring consistent and dependable performance.

IEEE 730 defines the standard for software quality assurance plans. It provides guidelines and requirements for creating a plan that ensures software quality throughout the development process.

The primary purpose of using an API in software development is to enable interoperability between different software components. APIs facilitate communication and data exchange between applications, allowing them to work together.

System testing focuses on validating the entire software system, ensuring that it meets the specified requirements and functions as intended. This includes verifying the software architecture, interfaces, and overall functionality.

Adherence to ISO/IEC 25010 ensures software product quality by defining and measuring quality attributes. It provides a framework for assessing and improving various software quality characteristics, including functionality, reliability, performance, and more, thus contributing to overall product quality.

Security is a critical quality attribute that pertains to the software's ability to safeguard against unauthorized access and data breaches. Security measures are implemented to protect sensitive information and ensure that only authorized users can access the system.

API stands for "Application Programming Interface." It is a set of rules and protocols that allow different software applications to communicate with each other. APIs define how software components should interact.

The "undo" heuristic in UI design is about providing users with the ability to reverse their actions. This feature adds a sense of control and safety for users, allowing them to correct mistakes or change their course of action.

System testing is positioned at the level where the entire software system is tested to ensure its correctness and functionality. It typically follows unit testing and integration testing, coming before acceptance testing in the testing life cycle.
