@@@@ Questions About Software Development @@@@
1. What is Software? Where/when/how it is used?
Ans: Computer software, or just software, is the collection of computer programs and related data that provide the instructions telling a computer what to do. We can also say software refers to one or more computer programs and data held in the storage of the computer for some purposes.

2. What is Software Development?
Ans: Software development (also known as Application Development; Software Design, Designing Software, Software Engineering, Software Application Development, Enterprise Application Development, Platform Development) is the development of a software product in a planned and structured process.

3. What is SDLC? Describe in detail.
Ans: Systems Development Life Cycle (SDLC) is a process used by a systems analyst to develop an information system, including requirements, validation, training, and user (stakeholder) ownership. Any SDLC should result in a high quality system that meets or exceeds customer expectations, reaches completion within time and cost estimates, works effectively and efficiently in the current and planned Information Technology infrastructure, and is inexpensive to maintain and cost-effective to enhance.
Systems development phases: Stages of SDLC can be characterized and divided up in different ways, including the following.
Project planning, feasibility study: Establishes a high-level view of the intended project and determines its goals.
Systems analysis, requirements definition: Refines project goals into defined functions and operation of the intended application. Analyzes end-user information needs.
Systems design: Describes desired features and operations in detail, including screen layouts, business rules, process diagrams, pseudocode and other documentation.
Implementation: The real code is written here.
Integration and testing: Brings all the pieces together into a special testing environment, then checks for errors, bugs and interoperability.
Acceptance, installation, deployment: The final stage of initial development, where the software is put into production and runs actual business.
4. What is Software Testing?
Ans: Software testing can also be stated as the process of validating and verifying that a software program/application/product: meets the business and technical requirements that guided its design and development; works as expected; and can be implemented with the same characteristics.
depending on the testing method employed, can be implemented at any time in the development process. However, most of the test effort occurs after the requirements have been defined and the coding process has been completed. As such, the methodology of the test is governed by the software development methodology adopted.
Maintenance: What happens during the rest of the software's life: changes, correction, additions, moves to a different computing platform and more. This, the least glamorous and perhaps most important step of all, goes on seemingly forever. In the following example (see picture) these stage of the Systems Development Life Cycle are divided in ten steps from definition to creation and modification of IT work products:
