What is the primary function of Instant Messaging?

The primary function of Instant Messaging is to facilitate real-time electronic text communication. This allows users to send and receive messages instantly, creating an interactive dialogue that is immediate and often informal. It targets the need for quick exchanges of information between individuals or groups, making it a vital tool in both personal and professional contexts.

While other options, such as sending large files or scheduling meetings, can sometimes be accomplished within certain messaging platforms, they are not the defining features of instant messaging. Video communication, similar to file sharing and scheduling, may be integrated into some instant messaging applications, but it is not the primary function. Instant messaging is centered around the exchange of short messages in a conversational format, which is why it holds such significance in contemporary communication practices.
