Pronunciation: [vˈalɪdˌe͡ɪtə] (IPA) 
The term "validator" is spelled with a "v" followed by an "a" pronounced as /ˈvælɪdeɪtər/. The "i" in the root word "validate" is pronounced with a short "i" sound as seen in the IPA transcription /ˈvælɪdeɪt/. It is derived from the Latin word "validus," which means strong or powerful. A validator is used in software development to check if input data meets specific criteria, ensuring that the data is accurate and reliable.
A validator refers to a tool, program, or system that is designed to inspect, authenticate, verify, or validate the accuracy, correctness, completeness, or compliance of something with a set of predefined standards, rules, criteria, or specifications. In the context of digital technologies, particularly programming and web development, a validator is commonly used to ensure that the code or markup language adheres to industry standards or specific guidelines.
A validator examines the syntactical structure, formatting, and logical consistency of a document, code, or data, often checking for errors, bugs, omissions, or non-compliance with a particular protocol or standard. It assists in identifying and rectifying any issues or inconsistencies that may cause problems in the execution, interpretation, or functionality of the data or code.
Validators are commonly employed in various industries, including web development, computer programming, data management, and electronic document processing. They play a crucial role in ensuring high-quality standards, data integrity, and interoperability across different systems and platforms.
Validators can be standalone tools or built into integrated development environments (IDE), text editors, or specialized software applications. They are typically equipped with predefined rules, libraries, databases, or algorithms that facilitate the validation process by comparing the input against pre-established criteria. Validators commonly generate error reports, logs, or notifications to highlight and assist in resolving any identified issues, allowing developers, designers, or administrators to produce reliable, compliant, and error-free outputs.
The word "validator" is derived from the Latin verb "validare", which means "to make strong, validate, or confirm". It is formed from the combination of the word "validus", meaning "strong" or "effective", and the suffix "-ator", which denotes the agent or doer of an action.
