INTERNET AND INTRANET DIFFERENCES - SOURCE CODE EDITORS

WHAT IS INTERNET

Definition - Internet is a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols. It also means of connecting a computer to any other computer anywhere in the world via dedicated routers and servers. When two computers are connected over the Internet, they can send and receive all kinds of information such as text, graphics, voice, video, and computer programs.


No one owns Internet, although several organizations the world over collaborate in its functioning and development. The high-speed, fiber-optic cables (called backbones) through which the bulk of the Internet data travels are owned by telephone companies in their respective countries.

The Internet grew out of the Advanced Research Projects Agency's Wide Area Network (then called ARPANET) established by the US Department Of Defense in 1960s for collaboration in military research among business and government laboratories. Later universities and other US institutions connected to it. This resulted in ARPANET growing beyond everyone's expectations and acquiring the name 'Internet.'

The development of hypertext based technology (called World Wide Web, WWW, or just the Web) provided means of displaying text, graphics, and animations, and easy search and navigation tools that triggered Internet's explosive worldwide growth.

 INTERNET INTRANET


The Internet is a global network connecting millions of computers. More than 190 countries are linked into exchanges of data, news and opinions. According to Internet Live Stats, as of December 30, 2014 there was an estimated 3,037,608,300 Internet users worldwide. The number of Internet users represents nearly 40 percent of the world's population. The largest number of Internet users by country is China, followed by the United States and India.

In September 2014, the total number of websites with a unique hostname online exceeded 1 billion. This is an increase from one website (info.cern.ch) in 1991.

DIFFERENCE BETWEEN INTERNET AND INTRANET

INTERNET

  • Internet is network of Computers which is open for all.
  • Internet itself contains a large number of intranets.
  • Unlimited number of users.
  • Visitor’s traffic is unlimited.
  • Contains unlimited source of information.
  • Collection of various LANs, WANs and MANs.


INTRANET

  • Intranet is network of Computers designed for a specific group of users.
  • Intranet can be accessed from Internet but with restrictions.
  • Limited number of Users.
  • Limited visitor’s traffic.
  • Contains only specific group purpose information.
  • Mostly any of LAN or MAN or WAN.


EXPLANATION OF DIFFERENCE BETWEEN INTERNET AND INTRANET

  • The main differences in Internet and Intranet are as follows
  • Internet is general to PCs all over the world whereas Intranet is specific to few PCs.
  • Internet has wider access and provides a better access to websites to large population whereas Intranet is restricted.
  • Internet is not as safe as Intranet as Intranet can be safely privatized as per the need.


The Internet is an open, public space, a worldwide system of interconnected computer networks. It is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a network of networks that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked Web pages and other documents of the World Wide Web.

The Internet is a combination of several media technologies and an electronic version of newspapers, magazines, books, catalogs, bulletin boards, and much more. This versatility gives the Internet its power.

While an intranet is designed to be a private space. An intranet may be accessible from the Internet, but as a rule it's protected by a password and accessible only to employees or other authorized users.

From within a company, an intranet server may respond much more quickly than a typical Web site. This is because the public Internet is at the mercy of traffic spikes, server breakdowns and other problems that may slow the network. Within a company, however, users have much more bandwidth and network hardware may be more reliable. This makes it easier to serve high-bandwidth content, such as audio and video, over an intranet.
