Instant messaging (IM) is a type of communication that allows people to send and receive real-time text messages over the Internet. Unlike email, which may have delays in response, instant messaging enables immediate conversations between users. IM is commonly used on smartphones, computers, and other devices, often through apps or software like WhatsApp, Facebook Messenger, or Skype. Some instant messaging platforms also allow for voice or video calls, file sharing, and group chats, making it a versatile tool for both personal and professional communication.
