Short note of Intranet, Extranet and Internet.

 

A. INTRANET.



An intranet is a private network contained within an enterprise that is used to securely share company information and computing resources among employees. An intranet can also be used for working in groups and teleconferences. Intranets encourage communication within an organization.
They let employees easily access important information, links, applications, forms and databases of company records. A database that includes all the usernames of employees who have access rights to the network is often used to maintain intranet security.

USES OF INTRANET.

1. Central repository. Intranets become the main repository where important information and company data are stored. 2. Collaboration. These internal networks provide a way to share information that makes it easier for employees to work together.

3. Personalization. Intranets provide personalized content to employees based on their role within the company.

4. Communication. They make employee directories, company news and organization charts readily available, improving internal corporate communications.

5. Easy access to information. Intranets provide easy access to information about company policies, benefits and updates.

6. Social elements. Social media features let employees create an account, post content and status alerts and browse a newsfeed.

7. Project management. To-do lists, employee directories, status updates and other resources aid users in project management.

8. Automation. Intranets streamline everyday activities by helping to automate repeatable tasks.

ADVANTAGE OF INTRANET.

1. Improved communication, information sharing and collaboration within a business;

2. Simplified records management;

3. Streamlined tracking of requests;

4. A testing environment for new ideas before they are implemented on a company's webpage;

5. Improved corporate culture that focuses on employees and encourages participation and interaction; and

6. A favorable return on investment from low implementation and operating costs.

DISADVANTAGE OF INTRANET.

1. Low user participation rates can result in a lack of the content, communications and documents needed to make the intranet beneficial.

2. The high cost of personnel leads to inadequate support for intranet users. As a result, when software bugs or other issues arise, problems are not resolved quickly.

3. The network must be managed, with regular inspections and maintenance checks to ensure it is running properly and content is fresh and relevant.

4. A lack of proper ownership or ownership being distributed among groups complicates network responsibilities and management.

5. A lack of mobile device and remote support creates problems, including limiting the ability of remote workers to access information on the intranet.
 

B. EXTRANET.



An extranet is defined as a private network that uses Internet protocols and public telecommunication systems to securely share part of an organization's information or operations with suppliers, vendors, partners, customers, or other businesses.

Extranets are usually created by organizations that have a large number of business partners and need to securely share sensitive information with them. Extranets can be accessed by anyone who has been granted access by the organization. Access to an extranet is usually granted to specific individuals within an organization's business partners through the use of a login system and credentials.

USES OF EXTRANET.

1.An extranet can be used to facilitate secure communication between an organization and its business partners.

2.Extranets are often used to share confidential information, such as product designs or financial data, with authorized external users.

3.Extranets can also be used to create virtual private networks (VPNs) between an organization and its business partners. VPNs allow organizations to securely share information over the public Internet without the need for expensive private leased lines.

ADVANTAGE OF EXTRANET.

1. Sharing of Confidential Information: They can be used to securely share confidential information with authorized external users. This can include things such as access to sales information, pricing information, promotion information, and data on inventory listings.

2. Improved Communication and Collaboration: Extranets can improve communication and collaboration between an organization and its partners. This is because they provide a secure way to share information and track projects. This can also help to avoid misunderstandings and miscommunication.

3. Cost Savings: Extranets can save organizations money by eliminating the need for expensive private leased lines. 4. Increased Efficiency: Extranets can increase the efficiency of an organization by providing a central location for information and resources.

DISADVANTAGE OF EXTRANET.

1. One disadvantage of using an extranet is that it requires a high level of trust between the organizations involved.

2. Setting up and maintaining an extranet can be costly.
 

C. INTERNET.



Internet defined as a worldwide system of computer network.
Or is a worldwide network that links computers. People may exchange information and converse through the internet from any location with an internet connection.

DIFFERENT BETWEEN INTRANET, EXTRANET AND INTERNET.
INTRANET EXTRANET INTERNET
An intranet works on a private network of computers. Only authorized people and systems can access it. They also must connect to the intranet via the required LAN or VPN. An intranet typically can host a specific number of users. An extranet is an intranet that grants access to those outside of an organization to certain information and applications. Third parties such as customers, vendors and partners are given access to certain parts of the organization's intranet. The internet works on a public network that anyone can access. There are no limits on who can access the internet, other than users must have access to a computing device that's connected to the internet. The public internet can have unlimited users at any one time, but it is more vulnerable to attackers than an intranet.
