Instant Messaging (IM) is a type of online chat that offers real-time text transmission over the Internet. A LAN messenger works similarly on a local area network. Short messages are typically transmitted between two parties, when each user chooses to complete a thought and select "send". Some instant messaging applications can use push technology to provide text in real time, which transmits messages character by character, as they are composed. More advanced instant messaging can add file transfer, hyperlinks clicks, voice over IP, or video chat.
Non-instant messaging chat types include multicast streaming, commonly referred to as "chat rooms," where participants may be anonymous or may be previously known to each other (for example, collaborators in a project that uses chat to facilitate communication). Instant messaging systems tend to facilitate connections between specified known users (often using a contact list also known as a "friends list" or "buddy list"). Depending on the IM protocol, the technical architecture may be peer-to-peer or client-server (an instant messaging service center relays messages from the sender to the communication device).
Instant messaging is a set of communication technologies used for text-based communication between two or more participants via the Internet or other types of networks. IM-chat takes place in real time. Of importance is that online chat and instant messaging differ from other technologies such as email due to the perception of almost synchronization of communications by users. Some systems allow messages to be sent to unconnected users (offline messages), eliminating some differences between instant messaging and e-mail (often sending the message to the associated e-mail account).
IM allows effective and efficient communication, allowing immediate receipt of acknowledgment or response. However IM basically is not necessarily supported by transaction control. In many cases, instant messaging includes additional features that can make it even more popular. For example, users can see each other through webcams, or speak directly for free via the Internet using a microphone and headphones or speakers. Many applications allow file transfers, although they are generally limited in the allowed file size.
