And the most important is that most chat services are free and you’ll always have the latest version of it, because no installations or updates of software are required.
It’s a term with a broader meaning, because, unlike instant messaging programs, which are intended for one-to-one communication, it enables or makes it possible for multiple users to take part in the same conversation, typically known as videocalling or videoconferencing.

Chat room can be used as a technology for information sharing online through text with other users.
A web chat is a special system or service that allows real time communication for users that use easy-to-access web interfaces.
It’s an internet online chat type that is user-friendly and fully accessible by users, without need to install any specialized software for chatting.
Online communication, or chat, can be divided into two types: text chat and video chat, which has become the most widespread mean of online communication since webcam became popular.
