The global system of interconnected computer networks which uses Internet Protocol Suite like TCP and IP to make connection between Networks and Devices.

The linking of a broad array of optical networking, electronic and wireless technologies, the Network of Networks which consists of private, public, academic, a local to global reach of the network is known as Internet.

Internet carries a vast range of information and resources like the interlinked Hypertext, File sharing, e-mailing, World Wide Web(WWW). 

The Time Sharing of computers, the research carried out by the United States Department of Defense, marks the origins of Internet as the part of packet-sharing.

The ARPANET served as the backbone for the interconnection of military and the regional networks at the time of 1970s. The funds collected from the National Science Foundation Network, acts as a new backbone for the modern Internet in 1980s, as well as for other commercial extensions.

Each of the network sets its own policies, whereas each constituents have their own policies.

The two principals of the overreaching name definitions of the name spaces of the internet are Domain Name System and the Internet Protocol Address commonly known as the IP Address. 

These two spaces are maintained by the maintainer organizer, the Internet Corporation for Assigned Names and Numbers(ICANN). The technical work and the standardization of the Internet Protocols is the work of Internet Engineering Task Force(IECN). 

INTERNET-A pack that ends all issues

History of Internet:

The seeds of the Internet were planted in 1969, when U.S. Department of Defense sponsored a project named ARPANET(acronym for Advanced Research Project Agency NETwork). In mid 80s another federal agency, the National Science Foundation, created a new, high capacity network called NSEnet, which was more capable than ARPANET. 

It was the Inter-networking, i.e. the linking of these two and some other networks(i.e. the ARPANET , the NSFnet and other private networks) that was named Internet.

The original ARPANET was shut down in 1990, and the government funding for NSFnet discontinued in 1995. The commercial Internet services which come into frame afterwards are still running the Internet. 

Advantages of Internet:

  • Greater access to information reduces research times.
  • Useful connection links.
  • Worldwide reach enables one to connect to anyone on the Internet.
  • Easy communication with other people.
  • A valuable resource for companies to advertise and conduct business.
Disadvantages of Internet:
  • Unsuitable and Undesirable material available that sometimes are used by notorious people such as terrorists.
  • Most of the times viruses gets installed by itself while surfing from internet which can make security issues.
  • Most of the information may be unchecked may be incorrect and irrelevant.
  • There is no perfect end-to-end encryption while working or chatting on the Internet which can make environment worst for an individual.
  • Credit/ Debit cards numbers can easily be hacked i.e. cyber frauds and cyber attacks can be done.
World Wide Web:

The WWW is a set of programs, standards and protocols governing the way in which multimedia files (multimedia files are the documents that contain a combination of text, photographs, video and audio) are created and displayed on the Internet.

WWW was proposed between 1989-1991 by Tim Berners Lee.


History of WWW:

Present day WWW is about 28 years of age with its official birth date as April 30, 1993.


On March 12, Tim Berners-Lee, a British scientist working at CERN in Switzerland, submits a proposal for a "distributed information system" to allow researchers to deal with huge amounts of information. 


(20 December) World's first website goes live on


As Berners Lee publishes the details of this WWW project, it was released publicly.


The Source Code for world wide web was released on April 30, by CERN, which was announced free of charge.
A basic browser was also released. The browser was released with a library of code.
It counts for about 1% Internet traffic. 

Difference between Internet and WWW:

Most people think that WWW is Internet and vice versa, which is NOT TRUE. A large part of the Internet is the World Wide Web (WWW). This is made up of web sites that have one or more web pages.

The Internet also have Email and Instant Messaging (IM) systems.

It is really important to understand that the Internet is not the same as the WWW. The Internet is to the World Wide Web as Europe is to Germany. One is the container, the other is an item within the container.

Advantages of WWW:
  • It helps in easy availability of useful information.
  • The cost of the initial connection is low.
  • It helps in rapid interactive and easy communication between two individuals or groups.
  • It can exchange a large amount of data at a very low cost.
Disadvantages of WWW:
  • There can be the high risk of overload and excess information.
  • There are no specific policies or regulations for the users.
  • No control on quality of the data available.
  • The search can be slow sometimes based on traffic or maybe the data connection may vary.
