Instant messaging (IM) is a real-time, text-based form of communication that allows people to communicate with one another over the internet. IM is typically done through a computer program or mobile app that allows users to send and receive messages in real time.
One of the main advantages of IM is that it allows users to have a conversation in real-time, rather than waiting for a response as they would with email. This makes it a faster and more efficient way to communicate, especially when time is of the essence. IM is also a popular way to communicate because it is often free and does not require a phone connection.
IM is commonly used for personal communication, but it is also used in business settings as a way for coworkers to communicate and collaborate on projects. Some popular IM programs include Skype, Slack, and Google Chat.
