MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Explanation: In case of client/server applications, the concurrent process model specifies activities in two dimensions: a system dimension and a component dimension. Hence Concurrency is achieved by these two activities occurring simultaneously and can be modeled using the state-oriented approach.

Detailed explanation-2: -1. Spiral model is a software development model and is made with features of incremental, waterfall or evolutionary prototyping models. Incremental Model is a software development model where the product is, analyzed, designed, implemented and tested incrementally until the product is finished.

Detailed explanation-3: -It generates working software quickly and early during the software life cycle. It is more flexible and less costly to change scope and requirements. It is easy to manage each iteration.

Detailed explanation-4: -Explanation: A spiral model is an incremental approach, which is formed as a combination of the waterfall model and prototyping model.

Detailed explanation-5: -The spiral model, initially proposed by Boehm, is an evolutionary software process model that couples the iterative feature of prototyping with the controlled and systematic aspects of the linear sequential model.
