Internet a miracle

Internet is like an act that of a magician.The miracle that internet had made to happen is really mind boggling ones.We can find everything on Internet that has put the world knowledge in a computer box.

The internet had its origin in the DOD's(Department of Defense USA)efforts to build a controller that can get entry in any network that is very broad,stubborn and sturdy.Few years back DOD officials were worried because there were no such device to which you can connect almost any other network or computer.The DOD officials wanted to create a fault tolerant Wide area network that could carry,command,and control information in the event of a nuclear war.Thorough research was made and the result was the Interet Protocol(IP) and ARPANET(Advance Research Projects Agency Network),though original aim of this research was military,it was soon used for other purposes.

upto 1990's the internet was largely used by academic,government and industrial researchers.But with the invention of new application the WWW(world wide web)millions of new non academic users were added to the Internet.

What is Internet?

Everybody talks about the Internet now a days,but most people dont really know ,what actually it is.

Briefly speaking ,"Internet is a web which has a very large nummbers of computers connected to each other".These computers are connected with one and the another either through wire ,satellite ,microwaves or fibre optics cables.They are so programmed using many software browsers,such as Internet explorer or Netscape Navigator,that one can communicate from one computer to another computer within minutes..No one "own"the internet service .No one even really runs it.And no  one can turn it off or on.

In other words,Internet is essentially a big network that links smaller net works and individual computers all over the world using modems,phone lines and satellite links.

Everyone is welcome in the arms of internet as long as ones computer runs the communication protocol /Internet Protocol (TCP/IP).This universal standards allows different types of computers to communicate to each other,regardless of their make ,model or operating system.In order to communicate to each information to traavel on Internet , a computer breaks down the information /message into smaller chunks of data called 'packets' and send these packets through 'Modem'and through the telephone lines.These packets move separately from one line to another ,one network to another, till they reach their final destination ,where another computer gathers them all together and resembles them into the original message.The internet works in such a wonderful manner that even if one or the other phone lines are busy ,or a number of individual network go down ,data packets would find another route through different lines ,networks and computers to reach the final destination .
