The primary goal of software development is to create software that meets the needs and requirements of the users. This involves understanding the user's problems, designing a solution, and implementing that solution in a way that is efficient, reliable, and maintainable.

Deployment is not a fundamental phase of the SDLC. The fundamental phases of the SDLC are requirements gathering, design, implementation, and testing.

The purpose of an SRS is to define the functional and non-functional requirements of the software. This includes the features and capabilities that the software must have, as well as the constraints and limitations that it must operate within.

Singleton, Factory, and Observer are all common software design patterns. Design patterns are reusable solutions to commonly occurring problems in software design.

A compiler translates high-level code into machine code, while an interpreter executes high-level code line by line. A compiler generates an intermediate code, while an interpreter generates machine code. A compiler is faster than an interpreter.

Unit testing, integration testing, and system testing are all common software testing techniques. Unit testing tests individual units of code, integration testing tests how different units of code work together, and system testing tests the entire software system.

The purpose of a software maintenance plan is to define the activities and resources required to maintain the software, identify and fix bugs in the software, and update the software with new features and functionality.

Waterfall, Agile, and Scrum are all common software development methodologies. Waterfall is a traditional methodology that follows a sequential process, while Agile and Scrum are iterative methodologies that focus on delivering value early and often.

The purpose of an SCM tool is to track and manage changes to the software code, store and organize the software code, and facilitate collaboration among software developers.

Code reviews, unit testing, and integration testing are all common SQA techniques. Code reviews involve manually inspecting the code for errors, unit testing tests individual units of code, and integration testing tests how different units of code work together.

The purpose of a software release plan is to define the schedule and process for releasing the software. This includes identifying the release date, the features that will be included in the release, and the testing and deployment procedures that will be followed.

An IDE is a software application that provides a comprehensive set of tools for software development, including a code editor, debugger, and compiler. A VCS is a tool that tracks and manages changes to the software code. A BTS is a tool that helps software developers track and manage bugs.

The purpose of a software architecture diagram is to visualize the structure and organization of the software system. This includes the components of the system, the relationships between the components, and the data that flows between the components.

Buffer overflow, SQL injection, and XSS are all common software security vulnerabilities. Buffer overflow occurs when a program writes data beyond the boundaries of a buffer, SQL injection occurs when an attacker inserts malicious SQL code into a web application, and XSS occurs when an attacker inserts malicious JavaScript code into a web application.

The purpose of a software performance test is to measure the speed and responsiveness of the software, identify and fix performance bottlenecks, and optimize the software for better performance.
