Interview Question Based On Software
Categories: Software
Ques 1. What are the various categories of software? Ans. Software products are mainly categorized into: System software: Softwares like operating systems, compilers, drivers, etc. fall into this category. Networking and web development software: Computer networking software offers the necessary functionality for computers to communicate with one another and with data storage facilities. Embedded Software: Software used in instrumentation and control applications such as washing machines, satellites, microwaves, TVs, etc. Artificial Intelligence Software: Expert systems, decision support systems, pattern recognition software, artificial neural networks, and other types of software are included in this category. Scientific software: These support a scientific or engineering user's requirements for performing enterprise-specific tasks. Examples include MATLAB, AUTOCAD, etc. Ques 2. What are the drawbacks of the spiral model? Ans. The spiral model is a hybrid of the iterative development process and the waterfall model, with a focus on risk analysis. In the SDLC Spiral model, the development process begins with a limited set of requirements and progresses through each development phase. Until the application is ready for production, the software engineering team adds functionality for the increased requirement in ever-increasing spirals. Drawbacks of the spiral model are: a. It's significantly more complicated than other SDLC models. The procedure is intricate. b. Due to its high cost, it is not recommended for small projects. c. Risk Analysis is overly reliant, and it necessitates a high level of skill. d. Time estimation is challenging Ques. 3. What is Software prototyping and POC? Ans. A software prototype is a working model with limited functionality. The prototype may or may not contain the exact logic used in the final software program, and therefore is an additional work that should be considered in the calculation. Users can review developer proposals and try them out before they are implemented through prototyping. It also helps in comprehending user-specific details that may have been missed by the developer during product development. Ques 4. What are the merits of the incremental model? Ans. It can deliver iteration faster, in the first iteration itself. Development takes place in parallel to each other. We can reduce the first delivery cost by using this method. The user or client can provide feedback at each level and unexpected changes in the requirement can be avoided. Risks can be identified and managed on a module-by-module basis. Ques 5. What is Software scope? Ans. The scope of a software project is a well-defined boundary that incorporates all the activities involved in developing and delivering a software product. The scope defines what the product will and will not do, as well as what the final product will and will not contain. All capabilities and objects to be delivered as part of the software are explicitly defined in the software scope. Ques 6. What is the waterfall method and what are its use cases? Ans. The waterfall is the easiest and most straightforward SDLC approach in software development. In this approach, the development process is linear, and each step is finished one by one. As the name implies, development progresses downwards, much like a waterfall. The software has to cover the following phases in a waterfall model: Requirements a. Design b. Implementation c. Testing and integration Use cases: a. When requirements are well-defined and unchangeable. b. There are no ambiguous requirements or conditions. c. When the technology is well understood
