Differences between instant messaging, online messaging and chatrooms

The main differences between the three is that instant messaging and chatrooms you get to chat in real time and everyone in the chat has to be online but when emailing the people don’t have to be online and is not in real time. Emails get spoofs and spamming, but instant messaging like msn cant get spoofed or spammed. Chatrooms can be dangerous because you don’t know whom you are chatting too, so the safer option is to use instant messaging like msn. There is online messaging which can be sent as SMS to mobile phones or you can have chatrooms using SMS from a mobile phone.
