What is a structural diagram? - ANSWER - it visualizes static elements of
software, such as the types of variables and functions used in a program
What is a behavioral diagram? - ANSWER - It visualizes dynamic behavior
of a software, such as the flow of an algorithm
What are the two behavioral diagrams of UML? - ANSWER - A case
diagram and a sequence diagram
What is the structural diagram of UML? - ANSWER - A class diagram
What is a behavioral Case diagram? - ANSWER - It is used to visually
model how a user interacts with a software program

ANSWER - It is used to visually model the classes of a computer program.
A class is a code blueprint (flowchart) for creating an object

It supports decomposing programs into objects (C++, Java, Python, C#)
What is the main characteristic of Interpreted/Scripting Language -
ANSWER - It runs sequential statements by another program called an
interpreter (Python, Javascript)
What is the main characteristics of a Compiled Language? - ANSWER - A
program which is converted by a compiler into machine code which runs on
particular machines (C++, Java)
What is SDLC? - ANSWER - The System Development Life Cycle is the
development phases of programs
What is the Waterfall Approach? - ANSWER - A program built by carrying
out each SDLC phase in sequence
What are the four phases of SDLC? - ANSWER - Analysis, Design,
Implementation, and Testing
What is the Agile (Spiral) Approach? - ANSWER - A program built by doing
small amounts of each SDLC phases in sequence, then repeating the
process
