Answer / jaya

In case of Waterfall model The phases are implemented sequentially while in the case of v model phases will be implemented paralley.

In case of water fall model user requriements does not change but not the case in V model(we can change the requriments)

In case of water fall model testing will be performed after the coding completion only .while in the case of V model coding and testing will be performed paralley due to this we can identify and verify the bugs in the earlier stage
