	The word Verify And Verification can refer to: Verification and Validation Verification and Validation In software project management, software testing, and software engineering, Verification and Validation is the process of checking that a software system meets specifications and that it fulfils its intended purpose.... : In engineering Engineering Engineering is the discipline and profession of applying Technology and science knowledge and utilizing natural laws and physical resources in order to design and implement materials, structures, machines, devices, systems, and process that safely realize a desired objective and meet specified criteria.... or a quality management system Quality management system Quality Management System can be defined as a set of policies, Business processes and How-to required for planning and Execution in the core business area of an organization.... , "verification" is the act of reviewing, inspecting, testing, etc. to establish and document that a product, service, or system meets the regulatory, standard Standard A technical standard is an established norm or requirement. It is usually a formal document that establishes uniform engineering or technical criteria, methods, processes and practices.... , or specification requirements. By contrast, validation Validation The word validation has several uses:* In common usage, validation is the process of checking if something satisfies a certain criterion. Examples would include checking if a statement is true , if an appliance works as intended, if a computer system is secure, or if computer data are compliant with an open standard.... refers to meeting the needs of the intended end-user or customer. Verification (spaceflight) Verification (spaceflight) Verification in the field of space systems covers two verification processes: Qualification and Acceptance... : In the space systems engineering area verification covers the processes of qualification and acceptance. Verification theory Verification theory The verification theory is a Philosophy theory proposed by the Logical Positivism of the Vienna Circle. A simplified form of the theory states that a proposition's meaning is determined by the method through which it is Empiricism verified.... : A philosophical theory relating the meaning of a statement to how it is verified Third-party verification Third-party verification TPV is a process of getting an independent party to confirm that the customer is actually requesting a change or ordering a new service or product.... : Use of an independent organization to verify the identity of a customer Verify theory: To prove the truth or to determine or test the accuracy. In Computing In applications: File verification File verification File verification is the process of using an algorithm for verifying the integrity or authentication of a computer file. This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files.... Checking the formal correctness or integrity of a file Human verification (CAPTCHA) CAPTCHA A CAPTCHA or Captcha is a type of challenge-response authentication test used in computing to ensure that the response is not generated by a computer.... A device to verify that a user of a web-site is human to prevent automated abuse Speech verification Speech verification Speech verification uses speech recognition to verify the correctness of the pronounced speech. Speech verification doesn't try to decode unknown speech from a huge search space, but instead, knowing the expected speech to be pronounced, it attempts to verify the correctness of the utterance's pronunciation, cadence, pitch, and stress.... Checking of the correct speaking of given sentences In software development: Formal verification Formal verification In the context of hardware and software systems, formal verification is the act of Mathematical proof or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.... Formal mathematical proof of the correctness of algorithms Functional verification Functional verification Functional verification, in electronic design automation, is the task of verifying that the digital circuit conforms to specification. In everyday terms, functional verification attempts to answer the question "Does this proposed design do what is intended?" This is a complex task, and takes the majority of time and effort in most large ele... All forms of verification that an algorithm implements the specified functions Runtime verification Runtime verification Runtime verification is a verification technique that combines formal verification and Computer program execution.It is the process of detecting faults in a system under scrutiny by passively observing its input/output behavior during its normal operations.... A form of formal verification during execution Software verification Software verification Software verification is a broad and complex discipline of software engineering whose goal is to assure that software fully satisfies all the expected requirements.... An overview of techniques for verifying software Intelligent verification Intelligent verification Intelligent Verification, also referred to as intelligent testbench, is a form of functional verification used to verify that an electronic hardware design conforms to specification before device fabrication.... Form of verification that automatically adapts the testbench to changes in RTL. In circuit development: Physical verification Physical verification Physical verification is a process whereby an Integrated Circuit Layout is checked via EDA software tools to see if it meets certain criteria. Verification involves DRC , LVS , ERC , XOR , and Antenna Checks.... Verification of the design of a circuit In systems engineering: Testing to confirm that the system, subsystem or component meets documented requirements or specifications levied on the design. In ICT uses, it is used to check whether data entered meets that which is required to continue, for example - the user needs to be 18 years old to watch a video posted on the internet, when requested to enter his or her date of birth, the date of birth will have to be equal or greater to that which means they are 18 before being allowed to continue, if a date of birth entered is lower than that of an 18 year old they will be disallowed from watching the video. Verify - a dos command with which one can set if the data written on a disk are read afterwards for checking their correct content. Using Verify makes disk writes safer, but a bit slower. at
