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 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 difference between Vehicle Verification and Validation Services?
The two most important aspects of software quality assurance are these. Validation determines if the software is being produced appropriately, whereas verification determines whether the correct programmer is being generated. In a nutshell, verification relates to precision, whereas validation refers to the final product's value. Vehicle verification and validation services are important parts of numerous operations in a variety of industries. The purpose of checking out and confirming a layout is to ensure that it complies with the specifications or requirements established during the development process. Assessments and verification are conducted throughout the product designing process to ensure that designs meet product specifications. Design validation is also carried out to see if it satisfies the intended purpose and customer requirements. Following a successful hit verification, improvement teams must do validation testing on the unique manufactured product as well as in a simulated usage environment. Rheomold has its own process flow, which is determined by the product, the kind of testing, and the appropriate standards.
What is the difference between data varification and data validation?
Data validation makes sure that the data is clean, correct and meaningful, while data verification ensures that all copies of the data are as good as the original.
What are the four evolution of software engineering?
upgradation of old softwares. e.g- anti-viruses. provides opportunities for new jobs and latest requiremants. provides better interfacing between hardware & software.
What is difference between the data validation and data redundancy?
one is a validation the other is redundancy clue is in the name
What is difference between sdlc and stlc in software testing?
Software Development Life Cycle involves the complete Verification and Validation of a Process or a Project. Whereas Software Testing Life Cycle involves only Validation. Software Development Life Cycle involves business requirement specifications,Analysis,Design,Software requirement specifications,Development Process(Coding and Application development),Testing Process(Preparation of Test Plan,Preparation of Test cases,Testing,Bug reporting,Test Logs & Test Reports),Implementation and Maintainence . Whereas Software Testing Life Cycle involves Preparation of Test Plan,Preparation of Test cases,Testing,Bug reporting,Test Logs & Test Reports.

What is the difference between design verification and design validation in ISO 9000?
ANSWERDesign verification is a process whose purpose is to examine designoutputs and to use objective evidence to confirm that outputs meetdesign input requirements. Your purpose here is to see whetheryour design outputs meet your organization's design goals.Design validation is a process whose purpose is to examine productsand to use objective evidence to confirm that these products meetcustomer needs and expectations. Your purpose here is to seewhether your product does what your customer or userwants it to do under real-world conditions.
What is the difference between static white box testing and dynamic white box testing?
1.Static testing involves verification of activities of the developed software where as dynamic testing involves working with the software, giving input values and checking if the output is as expected. 2.Review's, Inspection's and Walkthrough's are static testing methodologies.Unit Tests, Integration Tests, System Tests and Acceptance Tests are few of the Dynamic Testing methodologies. 3.Static testing is done before the code deployment (verification stage) where as dynamic testing is done after code deployment(validation stage). 4.Static testing is more cost effective then dynamic testing.
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.
