In Angular, a service is a word that refers to a large category of capabilities. Any item, function, or feature that an app requires is referred to as a service. Service is generally used for a specific task, such as HTTP communication, transferring data to a cloud service, decoding text, verifying data, and so on. A service specializes in one thing and performs it very well. It differs from a component in that it is unaffected by HTML or any other form of display logic. A component typically employs numerous services to do different tasks.
