Difference between Internet and Intranet

In short, the difference between internet and intranet corresponds to the location of information and who can access it. In the case of the Internet, it is public and in an intranet (or Ethernet) it is restricted to people connected to the network.

Differences between Internet and Intranet

  • Access – The Internet is a network conceived in global terms and of public access, while an intranet restricts access to only the computers that are connected to the private network.
  • Connection – For the internet, a connection is required from one computer to another where the websites are hosted, in order to interact with the content. In intranet, although it happens in a similar way, it is an environment in which there are several users connected to share data in different ways and even to establish communication.
  • Local and physical access – On the internet it is assumed that the connection between the computers does not involve physical elements and is not local either. In the case of intranet, computers can be connected with cables to interact with each other, and all this locally.
  • Scalability – Internet by its search to be global and public, allows that the connections do not present a limit while the connection can be established. On an intranet there are limitations to scalability.
  • Applications – The Internet is used in different ways that depend essentially on the creativity of each developer and user. Although in an intranet the possibilities are very similar, the typical thing is that this method is chosen in companies, institutions or organizations that seek to privatize access to their network.

What is internet

Internet It is a network of computers in which each one of them is interconnected worldwide so that information is shared. Therefore, it is a network in which the devices are related to each other by using a language that is universal.

In turn, on the Internet, the computers interconnected worldwide do so through the TCP / IP protocol. There are several types of internet connection that can be established. The first was the connection by dial-up or using telephone line connectivity with a cable. Later other modern methods emerged such as ADSL, fiber optics or 3G and 4G connectivity for mobiles.

Internet Features

  • Universal – It is a phenomenon that extends throughout the planet.
  • Globalization – It has eliminated the barriers and borders of time and space.
  • Accessible – Many activities that it allows to develop and all this at low cost.
  • Social changes – The Internet has promoted social changes on a large scale and in a very short period of time.
  • Easy to use – No advanced or special knowledge is required for its use.
  • Anonymity – Due to its characteristics, it allows users to maintain a certain anonymity.
  • Overcrowding – Content circulates freely, on a large scale and quickly.
  • Freedom of expression – There is no owner as such that controls the content, so it has stimulated expression from diverse social sectors.

What is Intranet

A intranet It is a connection that occurs between devices but in a private way, so the information that resides in each of the interconnected computers will only be available to those who participate in that network. In the case of the internet, access is public.

Intranet

The intranet They are usually used to provide support within the same network or to facilitate access to certain files within the same network, but ensuring that everything happens in a private way.

Intranet types

They are classified according to the size and distance between computers


  • LAN (Local Area Network): They are the most common and the number of computers that are part of the network varies from 2 to 50 units that are connected close to each other. Example: Offices of the same company.
  • MAN (Metropolitan Area Network): They are a set of connected LAN networks. Example: University campus
  • WAN (Wide Area Network): They are worldwide in scope and use not only cabling but also satellite and radio frequency communication. Example: Global corporate networks.

Intranet Features

  • Confidentiality – The data to be used or used will be communicated in the correct or desired way.
  • Integrity – The data is protected from being modified by unauthorized acts.
  • Authentication – The identity of those who manipulate files or objects on the network will always have to be authenticated.
  • check – The security mechanisms for the network can be checked and it is done with some frequency.
  • Availability – The available resources will be guaranteed for the intranet participants, whenever they need them.
  • Speed – Decision-making is going to accelerate among the members of a team that are interconnected to the network.
  • Communication – Not only are files shared within the network, but communication advances, even with audios or videos.
