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.
We don’t necessarily need to meet each other in order to communicate, because we’ve got cell phones, computers, Internet, webcams that simplify this process and make it really convenient, especially if the person you would like to have chat with lives far away from your neighborhood.
And all this we can sum up as an online communication process.
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.
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.
Webcams are considered to be the most popular form of videotelephony, making them perfect low cost and flexible devices for using with many software clients to provide video calls & videoconferencing, chat room being the general term to describe any form of the latter, both synchronous and asynchronous.
