Editor's Notes
your computer is connected to the Internet and has a unique address. How does it 'talk' to other computers connected to the Internet? An example should serve here: Let's say your IP address is 1.2.3.4 and you want to send a message to the computer 5.6.7.8. The message you want to send is "Hello computer 5.6.7.8!". Obviously, the message must be transmitted over whatever kind of wire connects your computer to the Internet. Let's say you've dialed into your ISP from home and the message must be transmitted over the phone line. Therefore the message must be translated from alphabetic text into electronic signals, transmitted over the Internet, then translated back into alphabetic text. How is this accomplished? Through the use of a protocol stack . Application Protocols Layer Protocols specific to applications such as WWW, e-mail, FTP, etc Transmission Control Protocol Layer TCP directs packets to a specific application on a computer using a port number .Internet Protocol Layer IP directs packets to a specific computer using an IP address.Hardware LayerConverts binary packet data to network signals and back. (E.g. ethernet network card, modem for phone lines, etc.)
The ISP maintains a pool of modems for their dial-in customers. This is managed by some form of computer (usually a dedicated one) which controls data flow from the modem pool to a backbone or dedicated line router. This setup may be referred to as a port server, as it 'serves' access to the network
A web browser is an interface between you and the internet.Most browsers have a graphical user interface(GUI).they allow customers a means to connect to a location on the internet either by typing in the desired address or by clicking on hyperlinks to reach a site. There are many kinds of browsers available, Netscape Navigator, Internet Explorer.
