How this TCP/IP and HTTP differs. can anybody brief this pls. I also would like to know about webservers.

thanx in advance

TCP/IP is a protocol that works on any of the 64K ports on a computer.
HTTP is TCP/IP using port 80 only. A basic WebServer uses port 80 to serve pages. It uses other ports for file downloads. HTTPS uses a different port.

am expecting from u little more

There are roughly 64,000 ports on every computer that can be used for TCP/IP. If you are using Winsock, you can use any one of them. Only one program may access any given port.

Take a look at this page, describing what programs use each port:

This should help clear things up for HTTP:

The HTTP protocol is used primarily to transfer data between servers and clients in hypertext/hypermedia environments.
HTTP is built upon a request/response model. An HTTP client or its agent, often a Web browser, connects to an HTTP server by using a URL, and requests a resource, such as an HTML document. MIME is then used to encapsulate the requested data, and the data is sent back to the client.
Traditionally, HTTP clients and servers communicate over TCP/IP using port 80, the default TCP port assigned to HTTP. However, different ports can be used if the port is specified in the URL. In addition, HTTP can be used with other reliable protocols.
HTTP is maintained by the World Wide Web (W3C) Consortium.
For information on HTTP, see www.w3.org/protocols/HTTP/.

And this for TCP/IP

The TCP/IP v6 protocol is used by nodes to communicate with other nodes across a network, independent of the types of physical links present in the network.
RFCs for TCP/IP are stored by the Internet Engineering Task Force (IETF).
For information on TCP/IP, see http://www.ietf.org/rfc/rfc2460.txt and http://www.ietf.org/rfc/rfc1180.txt .
IP v6 is the successor to IP v4 (RFC 791).
IP v6 is sometimes referred to as IP Next Generation (IPng).
