It's utilized by a 'client' such as for instance a web browser to determine a reference to the server which hosts a certain site. The server waits for incoming requests by tracking TCP port 80. Transmission Get a handle on Protocol (TCP) is employed to generate connections between two computers on the web for them to exchange data. TCP has provisions for pinpointing the requesting computer and for transmitting information eventually stamps to ensure that it may be reassembled in-the correct order after it arrives at its destination. There are numerous TCP locations that have standard uses. TCP port 21, for example, is normally reserved for FTP (File-transfer Protocol) for downloading and uploading files. Port 80 is normally used for HTTP. When the server receives a request line on TCP port 80 in-the kind of GET / HTTP/1.1 it will send an answer signal depending on perhaps the requested web page can be obtained or maybe not. A normal demand goes like this GET /faq.html HTTP/1.1 Host http://www.mywebsite.com It is a request for http://www.mywebsite.com/faq.html.

If faq.html can be acquired the server may respond HTTP/1.1 200 OK Date Mon, 12 October 2005 22:38:34 GMT Server Apache/1.3.27 (Unix) (Red-Hat/Linux) Last-Modified Wed, 08 Jan 2003 23:11:55 GMT ...followed by the real website.

Because the data is obtained an acknowledgement is sent back by the client ( the web browser ). This means that most of the packets are received inside a certain time. Or even, they will be re-transmitted by the host. TCP also checks that the information is undamaged. The data is re-assembled in-the correct order thanks to the sequence number of every data packet.
