One, Web hosting
In the early days of the World Wide Web, each organization bought its own computer hardware, built its own computer room, applied for its own network connection, and managed its own web server software, and as the web became mainstream, everyone wanted a website, but few people had the ability or time to build server rooms, register domain names, Purchase network bandwidth, so there are providers that provide these services, and they provide specialized managed web hosting services that customers only need to provide Web content.
Second, virtual hosting
(1) A Web site cannot be dedicated to a physical server, which is a waste of server resources, so the physical server will be divided into multiple virtual hosts, so that a server can host multiple Web sites
(2) There can be many ways to access the Web site on the virtual host, such as through the domain name to access, through the port number to access, through the IP address to access, through the first field access
