Online chat may address point-to-point communications as well as multicast communications from one sender to many receivers and voice and video chat, or may be a feature of a web conferencing service.
Online chat in a less stringent definition may be primarily any direct text-based or video-based (webcams), one-on-one chat or one-to-many group chat (formally also known as synchronous conferencing), using tools such as instant messengers, Internet Relay Chat (IRC), talkers and possibly MUDs.
Thereby, a feeling similar to a spoken conversation is created, which distinguishes chatting from other text-based online communication forms such as Internet forums and email.
BOSTON – A digital advertising company that was hired to use mobile geofencing technology to target women entering reproductive health facilities has been prohibited from doing so in Massachusetts pursuant to a settlement announced today by Attorney General Maura Healey.
Geofencing is a technology that allows digital advertising companies to direct advertisements to users through browsers and applications on their devices when those users are located in a designated territory.
The expression online chat comes from the word chat which means "informal conversation".
Online chat includes web-based applications that allow communication – often directly addressed, but anonymous between users in a multi-user environment.
