    instant messengers by protocol

    instant messaging (im) technology is a type of online chat that offers real-time text transmission over the internet. a lan messenger operates in a similar way over a local area network. short messages are typically transmitted between two parties, when each user chooses to complete a thought and select "send". some im applications can use push technology to provide real-time text, which transmits messages character by character, as they are composed. more advanced instant messaging can add file transfer, clickable hyperlinks, voice over ip, or video chat.

    non-im types of chat include multicast transmission, usually referred to as "chat rooms", where participants might be anonymous or might be previously known to each other (for example collaborators on a project that is using chat to facilitate communication). instant messaging systems tend to facilitate connections between specified known users (often using a contact list also known as a "buddy list" or "friend list"). depending on the im protocol, the technical architecture can be peer-to-peer (direct point-to-point transmission) or client-server (an instant message service center retransmits messages from the sender to the communication device).

    by 2010, instant messaging over the web was already in sharp decline,[1] in favor of messaging features on social networks. the most popular im platforms, such as aim, closed in 2017,[2] and windows live messenger was merged into skype.[3] today, most instant messaging takes place on messaging apps which by 2014 had more users than social networks.[4]
