Basics of World Wide Web & Internet

Here we take some of introductory details about world wide web and internet that helps to run the web application and technologies work

#HTML (Hypertext Markup Language):

  HTML is a tagging language used to compose documents that will be viewed in a web browser.

  It is a standard adopted for no matter what computer platform someone is using, the web browser knows how to display the web document.

# Web Page:

  A mixture of text, graphics, sound and animation in the HTML format, to make information accessible in a easy to understand format using the Internet.

# Web Site:

  A collection of web pages connected (linked) by Hypertext clickable links.

# Web Site Storage/Hosting:

  After a web site is designed it must be stored on a computer that can be accessed through the Internet and the World-Wide Web .

# Protocol:

  It is a set of conventions governing the processing and the data in an electronic communications system.

# TCP/IP (Transmission Control Protocol/Internet Protocol ):

  TCP/IP is a set of protocols developed to allow cooperating computers to share resources across a network. They provide a few basic services that everyone needs (file transfer, electronic mail, remote logon, etc…) across a very large number of client and server systems.

# URL (Uniform Resource Locator):

  The URL is a “standard” way of easily expressing the location and data type of a resource. URLs in general take the form “protocol://address” where protocol is something like HTTP, FTP, telnet, and so on.

The address is merely the server name of a given resource or page.

# DNS (Domain Name Services):

  DNS refers to a network service that associates host names (alphanumeric) with their equivalent TCP/IP address. This is done by the means of a standard look-up table.

Example:

Translation from domain names:

http://www.flukyfacts.com

redirect to correct TCP/IP addresses, For example 185.162.147.35

# Telnet :

  Telnet is the way you can access someone else’s computer, assuming they have given you permission.

#SMTP (Simple Mail Transfer Protocol):

  SMTP is the standard protocol used to exchange Internet mail between TCP/IP hosts. “Message Handling Systems”

Domain (s) On the Internet. A domain is basically a registration category identifying geographic or purpose commonality.

There are seven top-level domains currently in use:

com – A commercial organization. The largest domain extension currently used.

edu – An educational institutions like a school or university.

gov – U.S government branch.

int – An international organization like the United Nations.

net – A network organization.

org – A non-profit organization.

mil – Reserved for A branch of the U.S military.

In other parts of the world the final part of the domain name represents the country in which the server is located like my for Malaysia, bb for Barbados, ca for Canada and uk for Great Britain.

#Internet:

At its most basic level, the Internet is an utility connecting localized computer networks (that might exist in a lab, in a building, in a department, or on a campus) with computer networks that extend across a wider area, like a region or a continent.

Two recent adaptations of the Internet technology are the Intranet and the Extranet. The term ‘Internet’ comes out of the concept of ‘inter networking’

#World-Wide Web:

The World-Wide Web (WWW) is a pair of software applications. It allows both distribution and access of information over the Internet. The web is not the Internet but a means of distributing and accessing the information on it.
