What does handler mean?
A handler is someone who handles, manages, or takes care of something on behalf of another person or system. The term is especially familiar in the context of animals, as a dog handler or animal handler, but it can also describe a person responsible for customers, events, requests, or specialized tasks. In computing and business, a handler may be a person, program, or system component that processes a particular kind of input or request. The word often suggests active responsibility: a handler does not merely possess or own something but deals with it, coordinates it, or keeps it moving. Its meaning can range from a caring professional role, such as handling an animal safely, to a technical or administrative function. Because it is broad, the surrounding phrase usually determines the exact sense. The word is common in both British and American English and is neutral in tone.
