How instant messaging works? Write the steps involved in this process.
Answer:
The Instant Messaging services available allow us to maintain a list of people (contacts) that we interact with regularly. We can send instant messages to any of the contacts in our list as long as that contact is online.
Following steps are involved in IM working.
- User commences the IM client.
- IM client finds the IM server & logs in.
- It launches communication info (IP address, etc) to the IM server.
- IM server finds user’s contacts & sends him/her the communication info.
- IM server also notifies the contacts that the user is online; sends his/her communication info to them.
- The user’s & the contact’s IM clients are ready to communicate directly (P2P).
- As new contact has come online, IM server informs them about the user being online & vice versa.
- Multiple, real-time chat are possible.
- When the user logs-off, his/her IM client informs the IM server.
- IM server wipes away the temporary file and informs the user’s contact’s about his/her ‘offline’ status.
