The internet l.jpg

The Internet

  • The internet is a large connection of computers with protocols that allow computers to interact with one-another.

  • Some of the computers connected to the internet are connected as service providers.

  • Most computers connected to the internet are connected as personal use computers.

The Internet

  • Computers connect to the internet through an ISP (internet service provider)

  • The ISP provides the medium in which the transfer of information occurs.


Components l.jpg

Components

  • The IP address is a number that specifies every computer connected to the internet.

  • Every time a user connects to the internet, the ISP (internet service provider) assigns an IP address to that computer.

IP Address

132.96.212.198

Components

  • Name servers convert domain names into an IP address.

  • We have domain names because remembering a series or numbers is harder than a name.

  • Also IP addresses are constantly changing. And even thought the IP addresses for servers are considered static, they still can change from time to time.

Name Server


Components6 l.jpg

Components

  • All servers use a port in order to allow users to connect to the server.

  • Different services like web servers, ftp servers, and e-mail servers are located on different ports.

Ports


Components7 l.jpg

Components

  • Internet protocol are rules or a set of guidelines that allow web browsers to interact with web servers.

  • These guidelines are set usually by a program which defines how the interaction between browser and server will occur.

Protocol


The process l.jpg

The Process

  • The first thing your browser does when you enter the web address of the site you are trying to view, is brake down the URL into three parts:

    • The Protocol

    • The Domain Name

    • The File

The Protocol/ The Domain Name/ The File

(HTTP://) (www.hotzpad.com) (index.html)


The process9 l.jpg

The Process

  • The browser connects with a name server, which then converts the domain name into the appropriate IP address.

  • Now the browser can connect to the server at that IP address on a port.

  • The port for the world wide web is 80.


The process10 l.jpg

The Process

  • The browser connects to the server using the get command.

  • Once connected it uses the protocol specified earlier to locate the File on the server.

  • The server can now send the html file back to the browser.


Web browser l.jpg

Web Browser

  • The web browser allows you to get information from web servers .

  • It also translates the html file it receives into a viewable web page.


Web servers l.jpg

Web Servers

  • There are Registrars that sell domain names and space on there servers for people who want to display information over the web.

  • Another option is to use your own computer as a server with web server software.
