Regional(regional)networks connect subscribers located at a certain distance from each 
other. It includes subscribers in major cities and economic regions of the country. The distance 
between subscribers of the regional computing network is tens or hundreds of km. 
Localthe computing network connects subscribers located in a small area. Currently, the 
local computing network is distributed in the area of the exact limit load. Usually such a network 
is connected to a specific place. The class belonging to the local computing network includes the 
network of enterprises, firms, banks, and offices. Such a network covers an area of 2-2.5 km. 
Global, regional (regional), local computing networks form a multi-network hierarchy. They create 
a powerful economic tool that processes a huge amount of information, providing access to an 
unlimited information resource. A local computing network can be included as a component of a 
regional network. A regional network can enter a global network, and finally, a global network can 
form a complex structure. 
An example.The Internet computer network is a famous global network. It includes many 
loosely connected networks. Every network connected to the INTERNET has a specific 
communication structure and a specific management structure. Within the INTERNET, for a given 
user, the structure and methods of connection between different networks do not matter at all. 
Today, personal computers, which have become an integral part of any management system, are 
causing a stir in the creation of a local computing network. This, in turn, created the need to develop 
modern information technology. The practice of using personal computers in various fields of 
science and technology, production has shown that local computing networks, not separate PCs, 
are more effective in implementing computing techniques. 
Computer networks. 
In business and schools, communication is mainly through computer sets. The Internet is 
the largest and most popular computer network in the world. The Internet is mainly used for 2 
purposes: exchange of information by mail and access to the WWW. The whole world spider web 
is called the web. It helps people to get information about their desired topic. The Web uses text, 
images, hyperlinks, graphics, animation, video, and audio. It is an infinite storehouse of 
information. The global Internet enables information sharing, electronic commerce, and 
communication between millions of people. The WWW is also an important basis for making 
business deals. A local computer network, sometimes called an intranet, is an organization's private 
computer network. It is based on the same communication standards as the Internet. An intranet is 
a smaller version of the internet that is used by employees. An intranet website is similar to a 
regular website, but it is private and only registered users can access it. An intranet, like the 
Internet, is used for data exchange. Intranet is an effective tool for companies to save money and 
time. It can bring enough benefits to the organization.
