What is the website domain name?

　Domain name (English name is domain name), also called network domain, is actually a string of name characters on the Internet computer, and it is unique. Used as positioning identifier when transmitting data. Domain names are separated by the English symbol ".", and the top-level domain names are fixed, such as .com/.cn/.net, etc. When purchasing a domain name, select the top-level domain name you want, and then enter the second-level domain name you want to register from the left side of the top-level domain name to form a complete domain name (such as baidu.com).

## Speaking of this, you may have discovered the existence of top-level domain names. A complete domain name must have a top-level domain name and a second-level domain name (some people think that there is a first-level domain name to the left of the top-level domain name, and there is controversy here). Then the domain name needs to be purchased, that is, paid. The payment cycle is calculated annually, with a minimum payment of one year required. The cost of purchasing a new domain name ranges from a few yuan to dozens of yuan. If you are interested, you can check it out on websites such as 10,000 yuan.

Judging from the expression of the domain name, you may think that this is already a website address?

Indeed, you can think so, and it is indeed a URL, but it is an inaccessible URL. What does that mean?

As mentioned before, the website is composed of domain name space. Many people ask for the URL of a website. In fact, most of them want to visit the website. From this point of view, the website address is not equivalent to the domain name, there is a difference between them. The domain name can be inaccessible, and the URL can access the website.

The domain name does not require server space and can exist independently, but the URL that can access the website content requires the support of the server (space). In other words, what netizens think of as a URL is more often than not a combination of a domain name server (space).

A domain name can be equated with a web address, but not all web addresses can be considered domain names.

For example, the blog domain name is ***.com (replace it with an asterisk to avoid suspicion of advertising), and then this domain name is resolved to the IP123456 (assuming) server, and this domain name can be accessed normally. That is what we usually think of as a URL. However, Xizi added column 1 and column 2 to such a URL (such as ***.com/1, ***.com/2). This form is also a URL. They are URLs with different presentation forms derived from the main domain name. , but they cannot be called domain names.
