It is possible to offer real-time technical support through the Internet. As a matter of fact, there are several mechanisms for offering such real-time technical support through the Internet.
One mechanism for offering real-time technical support through the Internet is that in which the technical support is mediated via Internet Protocol – IP – telephony.
Another mechanism for offering real-time technical support through the Internet is that in which the technical support is mediated through email. For this to work, the emails would have to be replied as soon as they come in, thus simulating something akin to a real-time interaction with the people seeking technical support.
Yet another mechanism for offering real-time technical support through the Internet is that in which the technical support is mediated through Instant Messaging clients. Some of these, as you come to learn, are actually integrated with email systems. A good example is the Google Talk Instant Chat client, for which you can sign up simultaneously with Gmail at address given in this post.With the account thence created, it would follow that you’d also be logging into the Instant Messaging system every time you go through the www.gmail.com login procedures. This sort of a system can subsequently be integrated, through the API, to serve as a system for providing technical support, in real time, through the Internet.
