IM allows effective and efficient communication, allowing immediate receipt of acknowledgement or reply. However IM is fundamentally not necessarily supported by transaction control. In plenty of cases, instant messaging includes added features which can make it even more popular. For example, users may even see each other by webcams, or talk directly free over the Web using a microphone and headphones or loudspeakers. Plenty of applications permit file transfers, although they are usually limited in the permissible file-size.
Instant messaging is a set of communication technologies used for text-based communication between or more participants over the Web or other types of networks. IM�chat happens in real-time. Of importance is that online chat and instant messaging differ from other technologies such as electronic mail due to the perceived quasi-synchrony of the communications by the users. Some systems permit messages to be sent to users not then 'logged on' (offline messages), thus removing some differences between IM and electronic mail (often done by sending the message to the associated electronic mail account).
It is usually feasible to save a text conversation for later reference. Instant messages are often logged in a local message history, making it similar to the persistent nature of emails.
