URL, url, domain name

Url

(Uniform Resource Locator) The Uniform Resource Locator is a concise representation of the location and access methods of resources that can be obtained from the Internet, and is the address of standard resources on the Internet. Each file on the Internet has a unique URL that contains information that indicates the location of the file and how the browser should handle it.

The general form of a URL consists of the following four parts:

< protocol >://< host >:< port >/< path >

Example: http://www.tsinghua.edu.cn/index.html

Where HTTP is the protocol, www.tsinghua.edu.cn is the host name, the port is omitted, the final file is index.html.

Url

According to Wikipedia, URLs are the same as URLs.

Domain name

The basic concept of the domain name I will not say more, in the previous blog introduced very clearly, I would like to stress here is the relationship between the domain name and the former two. the domain name is part of the URL . Www.tsinghua.edu.cn is a hostname that represents the name of a server on a network that consists of a domain name. CN is a domain name,. edu is a level two domain name,. Tsinghua is a level three domain name, and www is a four-level domain name.

Summarize

URLs are the same thing as URLs, and domain names are part of it.
