Quizplus · Accepted Answer

SMTP (Simple Mail Transfer Protocol) and HTTP (Hypertext Transfer Protocol) are both used to transfer data over networks, but they do not have the capability to indicate the online status of users or support real-time communication. In contrast, instant messaging (IM) allows users to see the online status of their contacts and engage in real-time communication through text, voice or video messages. While file exchange and text messaging are also features of IM, they are not unique to this platform as they can be performed through other means (such as email or SMS messaging).
