Explanation / Answer

If you post more than 1 question, as per chegg guidelines I have to solve only 1 question.

Ques 1.

In System modelling, we create a conceptual model to describe and represent a system.It is a structured model which displays all the aspects of the system and its developement like planning, requirements, structure, inputs and outputs required and implementation.

We represent the system with a graphical notation with arrows and boxes in which the different aspects of the developement are shown. Also, the model we make is an abstract model of the system.

It does not tell about the security of the system.

Answer : (d) Only (a) and (b)
