Corporate Messenger > Introduction
 

Corporate Messenger / Instant Messenger, IM is a software utility that allows users connected to the Internet or a corporate network to send text messages and files between other IM users in real time.

Instant messaging offers real-time communication and allows easy collaboration format. In contrast to e-mail, a user knows whether the other users of the IM are available or not. Instant messaging differs from ordinary e-mail in the immediacy of the message exchange and also makes a continued exchange simpler than sending e-mail back and forth. Most IM systems allow the user to set his/her status for example an online status or away status so other users are notified when the user is available, busy, or away from the computer. In IM system people are not forced to reply immediately to incoming messages. Some IM systems allow the sending of messages to people not currently logged on (offline messages), thus removing much of the difference between IM and email.
