Introduction To The Internet & World Wide Web

What is Internet?

  • The Internet is a global system of interconnected computer networks that use the standard internet protocol suite (means TCP/IP) to serve massive users all around the world.

  • It is a network of networks that consists of millions of private, public, business, academic and government networks of local to global scope that are linked by a broad array of electronic, wireless and optical networking technologies.



Above picture show you a way how internet distributes. How it works.

Introduction To Protocols and Routing

  • A protocol is a standard used to define a method of exchanging data over a computer network such as local area network, Internet, Intranet etc. Each protocol has its own method of how data is formatted when sent and what to do with it once received, how that data is compressed or how to check for errors in data.
  • One of the most common and known protocols is HTTP (Hyper Text Transfer Protocol), which is a protocol used to transmit data over the world wide web or we called Internet.
  • Routing is the process of selecting paths in a network along which to send network traffic. Routing is performed for many kinds of networks including the telephone network (circuit switching), electronic data networks and transportation networks we call WIKI 
  • In Internet working the process of moving a packet of data from source to destination.
  • Routing is usually performed by a decided device called a router.
  • Routing is a key feature of the Internet because it enables messages to pass from one computer to another and eventually reach the target machine.
  • Each intermediary computer performs routing by passing along the message to the next computer. Part of this process involves analyzing a Routing table determine the best path.

WWW

Lets see what is this WWW or W3 means. All we see every were in the Internet this WWW. the letters are the short form of World Wide Web. simply we called as the web. This is a system of interlinked hypertext documents accessed via the internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them via hyperlinks.

Data transfer

  • Digital Data that is moved from one place to another.
  • The data transfer rate (DTR) is the amount of digital data that is moved from one place to another in a given time.
  • Data transfer is usually measured in bits per second. For example, a typical low-speed connection to the Internet may be 33.6 kilo-bits per second (Kbps).

Some thing that we should talk with this topic is Communication.
The Internet, since discovered as a powerful communication tool has grown, expanded and spread through out the world like  wild fire.
It has since become arguably the most powerful source of communication and resource.
