Difference between verification and validation in software testing?
verification: Are we doing the right system? validation : Are we doing the system right?

What is System Verification?
In mission critical systems, especially when software is involved, system-level testing is required to be sure the system/software operates correctly. This is often called Verification & Validation. The two are related, but verification is concerned with testing the system functions against the requirements document (which is essential in a critical system). Each requirement should be testable, and all requirements should be tested. Validation is the process of testing that the system and software behaves as it should when interacting with other systems and components. Verification & Validation is a long, tedious, and expensive process but is essential for mission-critical systems such as where human life or large investment or one-of-a-kind technology is at risk.
What is software testing in simple words?
software is process to finding error ,bugs and validation against requirement.testing involves operation of the system.
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.
What is Hybrid system in validation?
A hybrid system in validation refers to an approach that combines both traditional and modern validation techniques to ensure the accuracy and reliability of processes or products. This may involve integrating manual validation methods with automated tools or utilizing a mix of simulation and real-world testing. The goal is to leverage the strengths of each method to achieve comprehensive validation while optimizing resources and efficiency. Hybrid systems are particularly useful in complex environments where different types of data and validation requirements coexist.

What are the difference between qualification and validation?
Qualification: A documented testing that demonstrates with a high degree of assurance that a specific process will meet its pre-determined acceptance criteria. Validation: A documented testing, performed under highly controlled conditions, which demonstrates a process consistently produces a result meeting pre- determined acceptance criteria While qualification is used to provide a high degree of assurance that a process is replicable under anticipated variable ranges, validation is used to describe how a system will perform under highly controlled conditions. Based on the definitions above, it is easy to see how these definitions are interchanged. However, the key difference is determined by whether or not the process under review operates under 'highly controlled' conditions. Answerd By S.K. Karimullah PharmEvo, Karachi, Pakistan
