What is verification & validation?

Answer Posted / priya

verification is the process of proving or demonstrating
that the program correctly satisfies the specifications.
“each step of the development process correctly echoes the
intentions of the immediately preceding step.”

Validation: Validation is the process of evaluating
software, at the end of the development process, to ensure
compliance with requirements.
that the verification community also uses the term
validation to differentiate formal functional verification
from extensive testing of a program against its
specifications
