Q1. a) The Software Development Life Cycle (SDLC) is a process used to design, develop, test, and maintain software applications. It consists of several stages including planning, analysis, design, development, testing, deployment, and maintenance. During each stage, the development team performs various activities such as gathering requirements, creating a design, coding, testing, and documenting the software. b) Two important documents in software engineering process are: Software Requirements Specification (SRS): It is a document that captures the requirements for a software application. It includes details such as user requirements, functional requirements, performance requirements, and other specifications. Software Design Document (SDD): It is a document that describes the architecture, design, and implementation details of a software application. It includes details such as system architecture, data flow, user interface design, and other technical specifications.
