The purpose of verification is to check that a product, service, or system meets a set of initial design requirements, specifications, and regulations. In the development
Phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service or system, then performing a review or analysis of the modeling results. In the post-development phase, verification procedures involve regularly repeating tests devised specifically to ensure that the product, service, or system continues to meet the initial design requirements, specifications, and regulations as time progresses.
Whereas validation is meant to check that if the development and verification procedures for a product, service, or system result in a product that meets the initial Requirements, specifications, and regulations. For a new development flow or verification flow, validation procedures may involve modeling either flow and using simulations to predict faults or gaps that might lead to invalid or incomplete verification or development of a product, service, or system. A set of validation requirements,
specifications, and regulations may then be used as a basis for qualifying a development flow or verification flow for a product, service, or system. It is a process of establishing evidence that provides a high degree of assurance that a product, service, or system accomplishes its intended requirements. This often involves acceptance of fitness for purpose with end users and other product stakeholders. This is often an external process.

What is the difference between defect detection and defect prevention?
The defects detection is the validation process. The defects prevention is a verification process.
What is the meaning of validation in software testing?
Validation is done at the end of the development process and takes place after verification process is completed. According to CMM we can also define it as the process of evaluating software during or at the end of the development process to determine whether it satisfies specified requirements.
Difference between data validation and data verification?
Data validation means to check for correctness, meaningfulness, and security of data that are input to the system. The simplest data validation verifies that the characters provided come from a valid set. For example, telephone numbers should include the digits and possibly the characters +, -, (, and ) (plus, minus, and brackets). A more sophisticated data validation routine would check to see the user had entered a valid country code, i.e., that the number of digits entered matched the convention for the country or area specified. Data validation might also check that all required fields are filled in before an online form was submitted. Data validation should also check that only data of an appropriate length is accepted. Failure to do so can make an application vulnerable to buffer overflow exploits. Validation should also prevent users from entering command strings in place of data. Data verification is a process that helps to determine whether data was accurately translated when data is transported from one source to another, is complete, and supports processes in the new system. During verification, there may be a need for a parallel run of both systems to identify areas of disparity and forestall erroneous data loss.
What is a Software Engineering Process Framework explain in detail?
Software product meets the customer requirement or not. Time to deliver the product to customer. Cost for development product. Validation and Verification at last maintenance cost
What is an alternative to server side verification?
There really isn't one. Any verification that is pushed to rely solely on the client-side is going to become subject to massive security issues. Because the verification would have to be run inside the user's own browsing environment, he/she could completely rewrite the logic used to perform that verification.You can use various AJAX techniques and/or cookies to simplify the verification process, but there's really no safe way of doing verification on the client without at least some interaction with the server.Relying on the client-side for this kind of thing is among the best ways to ensure a short career in web development.
Which comes first verification or validation?
verification
Why verification and validation apply together?
verification finds out the information. and validation makes sure its right
Difference between verification and validation in software testing?
verification: Are we doing the right system? validation : Are we doing the system right?
Why do you used validation?
A validation rule is simply to make sure that the data is entered correctly into the database (go onto bitesize-ICT-validation and verification for more info)
Why is the validation rule used when completing online shopping?
The validation rule is used in completing online shopping as it is a means of verification of identity and confirming legal and authorized transaction.
How validation and verification are used?
Validation means to after verification the data is correct or not, verification means cross checking the data with record , or with original documents.So its like your visa card is verified that its on your name, but its valid or not will be know by either you or the bank, means when you swipe you card if there is no money then the card is verified but not valid.
When does CMM applied in software validation and verification?
CMM verifies the quality of the overall software development process beginning from problem definition. Software validation and verification are the subitems of CMM.
What are the various testing methods?
1.verification 2.validation
Why do you use validation rules?
A validation rule is simply to make sure that the data is entered correctly into the database (go onto bitesize-ICT-validation and verification for more info)
What is the CVV on a credit card?
CVV is a code: Card Verification (Validation) Value.
What is the difference between SDLC and STLC?
SDLC has both verification and validation activities where as STLC has only validation activity. Simply STLC is a part of SDLC
What are the problems arises during the verification and validation of real system or product?
Verification is intended to check that a product, service, or system meets a set of initial design requirements, specifications. Validation is intended to check that development and verification procedures for a product, service, or system result in a product, service, or system that meets initial requirements, specifications. The biggest problem arises when something is verified but the fails validation.
