MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Deployment diagrams are used to visualize the topology of the physical components of a system, where the software components are deployed. Deployment diagrams are used to describe the static deployment view of a system.

Detailed explanation-2: -Also known as DFD, Data flow diagrams are used to graphically represent the flow of data in a business information system. DFD describes the processes that are involved in a system to transfer data from the input to the file storage and reports generation. Data flow diagrams can be divided into logical and physical.

Detailed explanation-3: -A Deployment diagram shows how and where the system is to be deployed; that is, its execution architecture. Hardware devices, processors and software execution environments (system Artifacts) are reflected as Nodes, and the internal construction can be depicted by embedding or nesting Nodes.

Detailed explanation-4: -The component diagram represents the components of a system, whereas the deployment diagram describes how they are actually deployed on the hardware. The deployment diagram does not focus on the logical components of the system, but it put its attention on the hardware topology.
