AOL Instant Messenger

AOL Instant Messenger

AOL Instant Messenger (AIM) developed by AOL Inc. is an instant messaging client that uses the OSCAR (Open System for CommunicAtion in Realtime) instant messaging protocol and the TOC protocol that allows communication between registered users in real time. Instant messaging (IM) uses the Internet to provide a service that offers quick transmission of text-based messages from sender to receiver. Hence, it falls under the umbrella classification online chat because it is bi-directionally exchanged, text-based, and happens in real time. Instant messages sent over a network can be a point-to-point communication or multicast communications from one sender to many receivers. AIM provides users a quick way to get connected and stay connected with their family, friends and business colleagues. The new Lifestream feature in AIM allows the addition of accounts like Facebook, YouTube and Twitter where users can follow posts and status messages to stay connected in real time. AIM is available on Windows, Mac, and mobile phones like iPhone and Windows mobile. AIM runs in platforms supported by Windows, Windows Mobile, Android, Mac OS X, Blackberry OS, and iOS.

a word of warning

Be careful not to rename the extension on .aby files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .aby. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
