SPIRAL MODEL The spiral model combines the idea of iterative development (prototyping) with the systematic‚ controlled aspects of the waterfall model. It allows for incremental releases of the product‚ or incremental refinement through each time around the spiral. The spiral model also explicitly includes risk management within software development. Identifying major risks‚ both technical and managerial‚ and determining how to lessen the risk helps keep the software development process under control

Bohr and the Atomic Model Niels Bohr’s model of the hydrogen atom—first published 100 years ago and commemorated in a special issue of Nature—is simple‚ elegant‚ revolutionary‚ and wrong. Well‚ "wrong" isn’t exactly accurate—incomplete or preliminary are better terms. The Bohr model was an essential step toward an accurate theory of atomic structure‚ which required the development of quantum mechanics in the 1920s. Even in its preliminary state‚ the model is good enough for many calculations

Outline and Evaluate Models of Memory. (12 Marks) There are roughly four models of memory in total‚ but two stand out and are used in this particular specification. Atkinson and Schifrin’s (1968) “Multi-Store Model” is one of them. Their model suggests that the memory consists of three stores‚ a sensory store‚ a short-term store and a long-term store; all three have a specific and relatively inflexible function. It stressed that information for our environment such as the visual or auditory
