The difference and connection between Local area Network and Internet

Local area network (Local Area Network), referred to as LAN, refers to a group of computers interconnected in an area. "a certain area" refers to the same office, the same building, the same company and the same school, etc., usually within a few kilometers. Local area network can achieve file management, application software sharing, printer sharing, scanner sharing, scheduling within the working group, e-mail and fax communication services and other functions. The local area network is closed and can be made up of two computers in the office or thousands of computers in a company.

A local area network is like some people who live in a courtyard can carry out common activities together.

Internet, that is, the international computer network composed of wide area network, local area network and stand-alone computer according to certain communication protocols. The Internet refers to the result that two computers or more than two computer terminals, clients and servers are connected with each other by means of computer information technology. People can send emails to each other with friends thousands of miles away, complete a job and play together.

If the local area network is a stream, many streams converge into large main streams, such as the Yangtze River and the Yellow River, which is the wide area network, and then flows into the sea, which is the Internet.

The Internet is made up of numerous Lans that converge to operators through WAN lines, and then interconnect with each other to form the Internet. The Internet is open and interconnected. If the local area network of a company or organization is not connected to the Internet, then this local area network does not belong to the Internet. The concept of company local area network, wide area network and Internet is the same as the above concept, but there is no real difference between corporate local area network and home local area network by adding some switches, AP, firewalls and home local area network.
