Why we r not using tcp instead of http

[maheswaran]

Hi I have a basic doubt.

Why we are not using tcp instead of http?

for example http://www.yahoo.com to tcp://www.yahoo.com

What is the difference and usage both of this?

This question has nothing to do with PHP, so I will move it to the Misc forum.

In the meantime google some for 'HTTP' and you will find many articles regarding this subject.

TCP and TCP/IP are just transportation and internet layers while HTTP is an
application layer and relies on the TCP/IP layer.

Yep, these are two completely different things.

According to wikipedia, the HTTP protocol would be a part of the Application Layer of the TCP/IP model, while the TCP protocol is a part of the Transport Layer...

The table in that link makes so much more sense :P
