Provide an example explanation of what a web service is.

A web service is a software component that provides specific functionality or data over a network (usually the internet) using standard protocols such as HTTP.

Example: Imagine you have an application that shows the weather. Instead of storing weather data within the app, it calls a web service that provides up-to-date weather information in a format understandable by the app (e.g., JSON or XML).

Thus, a web service allows different applications and systems to interact with each other, exchange data, and utilize functionality over the network.
