What does the extranet mean?

Extranet refers to the internet connected with the global network and not restricted by countries or regions. It is an open cyberspace that allows people to freely exchange and share information and resources around the world.

The emergence and development of extranet can not be separated from the popularity of Internet and the progress of technology. With the rapid development of the Internet, people can connect to the Internet through computers, mobile phones and other terminal devices to realize information transmission and exchange. Extranet refers to those websites, services and resources that users all over the world can visit.

One of the characteristics of the extranet is that it has no borders. On the extranet, people can communicate and cooperate with people all over the world anytime and anywhere, regardless of geographical location. Whether it is business cooperation, academic exchange or cultural sharing, the extranet provides a convenient platform. This borderless feature makes extranet an important tool in the era of globalization.

Another feature is the free flow of information. On the extranet, people can freely publish, obtain and share information. Information in news, entertainment, education, science and technology and other fields can be transmitted to all parts of the world through the external network. This free flow of information has promoted the spread of knowledge and cultural exchanges and enriched people's lives.

The development of extranet also brings some challenges and problems. First of all, the free flow of information also brings confusion and unreality of information. On the external network, it is sometimes difficult to judge the authenticity and credibility of information. Secondly, because of the borderless nature of the external network, it also brings new threats to network security. In addition, some countries and regions also restrict and censor the Internet, restricting people's access to information and freedom of speech.

The difference between extranet and intranet:

1, different network ranges

First of all, extranet refers to connecting computer networks all over the world, which is a public network. Extranet can access computers and servers all over the world through Internet connection. Users can use the extranet for various network activities, such as browsing web pages, sending emails, downloading files, etc. Extranet has a wide range and can be connected to any place, providing unlimited information resources and services.

On the contrary, an intranet refers to a local area network or a private network within an enterprise. Intranet is a closed network environment, which can only be accessed within an organization or company. It is used for resource sharing and information exchange within an organization, such as sharing files, printers, databases, etc. Intranet is relatively small, usually confined to a building or an organization.

2. Different access rights

Extranet is an open network, and anyone can access it through the Internet. Users can connect to the external network through computers, mobile phones and other devices, browse web pages and download files. However, access to the intranet is usually restricted, and only employees or specific users in the organization can access it. This is to ensure the security and confidentiality of internal resources.

3. Different security.

Extranet is a public network, and there are various network security threats, such as hacker attacks and virus infections. In order to protect users' privacy and security, extranet usually adopts various security measures, such as firewall and encrypted communication. However, the internal network is more secure than the external network. Because the intranet is a closed network environment, only authorized users can access it, which reduces the risk of external attacks.
