Difference between Internet and Intranet
Internet is the worldwide interconnection of all smart communication devices that have a valid IP. On the other hand, intranet is a privately owned part of the internet under which only a selected number of IPs are allowed to communicate. Intranet is commonly used in connecting computers of a certain organization to remain connected and don’t face any interference from the IPs outside the intranet. Most of intranet accessing modes refer to the website of the organization which can only be accessed by its employees who have a user name and password. However, the website and the servers for this purpose form the essential information technology foundation for the company. Thus, the website enables a network for its employees to connect irrespective of their location and time. The website, though available through the internet methods, is not accessible unless a gateway is provided for data exchange.
Internet is a collection of websites that are fairly connected to each other in every possible manner and readily accept new users to be registered irrespective of the fact that they are employees of that particular organization or not. The information shared on the internet is unbound in terms of location, type of data exchanged. Even though the internet regulatory organizations of various countries have some restrictions on the internet, the potential of internet exploitation is multifold extra than the network limited intranet. A clear difference between internet and intranet can be understood with the help of an example explained below.
Example of Intranet
Consider Facebook employees to be connected to each other through a back end interconnection. The interconnection of the employee computers makes them exchange crucial information and program codes very easily and swiftly over LAN. However, this interconnection portal is totally aloof from the Facebook accounts of the employees or their Gmail accounts. Hence, employees cannot access. To access the employee interconnection, they might have to open a different browser window or even activate an employee IM communicator. Whereas, in order to access the Facebook accounts, they need to activate any such pre-requisite and just logging on to the webpage would be enough requirement. The method through which only employees can connect and communicate is the intranet working and the connection through which employees can access Facebook and their Gmail accounts is internet enabled and is not restricted.
Need For Intranet
As an organization grows in terms of data and services, integration of all departments is highly desired. Even a little glitch in communication can cause big problems in data processing and fiscal matters. Installing a separate division that keeps the hard copies of all company services is quite lumber some and is difficult to maintain. When the data storage and access is turned into the software way with allowing only a selective number of people to access it, it not only becomes easier to access data but is also very cost effective as lesser amount of hardware is required by the organization then. Moreover, accessing data and calculating it becomes very easy. This functionality of easy employee access with significant security measures is provided by intranet.
Similarities Between the Internet and Intranet
In the current times, intranet can be considered more of a business tool which keeps an organization connected in a structured manner. It is, however, to be always remembered that intranet is a part of internet. Thereby, intranet does share some very basic features with the internet. Some of them are listed as under:
- Intranet uses the internet protocols including TCP/IP and FTP.
- Though the access is limited, intranet can work on any of the web browsers. Some organizations do have a customized web browsing environment as per their requirement.
- Organizations that have intranet services often have their own instant messengers or communicators. These can be compared to Yahoo Messenger or Gtalk applications.
Security features like firewall and encryption-decryption policies are applied using same or similar features that internet has. A number of organizations have different encryption techniques so that any undesirable breach of data is not possible because of patterned studies.
Among the features that make intranet different from internet, dynamic key change is one of the most advanced and is the one that makes intranet safer from internet. Under this security policy, the user’s login password gets changed at a specified regular interval. User, then, inputs a new password provided after that specified time interval. This minimizes the chances of any breach or data attack on the intranet services. This is one of the reasons that intranet is regarded as a safer network connection than the internet.
The commercial potential of internet is far more than that of intranet. The revenues that any company collects through internet advertisement and paid services of entertainment and news are far more than what is can harness through intranet usage. As a matter of fact, the websites on the internet are a very fine source of income for their owner while intranet services are established on company’s own expense and are not revenue or income focused.
Internet is more general, spreads to a larger population, provides a better access to all web based services and thus, is pretty user friendly. Intranet is a far safer and secure privatized version of internet. Solely for the purpose of communication, intranet is an economic method to keep the organization’s communication structured allowing quick data exchange round the clock all the year.
