Difference between Verification and Validation with methods of verification process

Verification:-

1.        In general, Verification is defined as “Are we building PRODUCT RIGHT?” i.e., Verification is a process that makes it sure that the software product is developed in the right way. The software should confirm to its predefined specifications, as the product development goes through different stages, an analysis is done to ensure that all required specifications are met.
2.        During the Verification, the work product (the ready part of the Software being developed and various documentations) is reviewed/examined personally by one or more persons in order to find and point out the defects in it.
