Global resource locator [computer network]

The Chinese name of URL(Uniform Resource Locator) is "Global Resource Locator", which is also translated as "Universal Resource Locator". It is an address that can identify the location of a computer, directory or file on the Internet, and can also specify communication protocols, such as Gopher and HTTP. URL enables all resources on the Internet to find their location in this way.

Introduction to URL

In the World Wide Web, if you want to link to a web page, you need to give the browser an address, and the role of the URL here is to tell the browser where a resource is. Simply put, the URL we usually enter in IE or Netscape browser is one of them.

HTTP (Hypertext Transfer Protocol) Hypertext Transfer Protocol is the most important communication mode between server and browser in WWW. In order to make the browser find the location of data on the network correctly, the browser determines the location of resources through URL. Usually, the URL does not necessarily point to a hypermedia file, but it can also be a service on the network, such as Ftp, Gopher and so on.

Format of URL

Urls are separated by "://". For example, the URL before "/"://"refers to the address of the server, where" www "is the World Wide Web," dreye "is the name of this station, and" com "refers to the type of domain name. Usually the most basic URL format is "protocol://link type, site name, domain name type, country" plus "country" (such as tw in Taiwan Province Province).

In terms of agreement, there are commercial organizations, edu is an educational institution, gov is a government, mil is a military website, and net is a network service company.

Through the above URL method, the network can be addressed and classified one by one, and the browser can find the location correctly; The website is not all English words, no matter how long it is, it can be converted into four groups of numbers.

Recently, the so-called Chinese website has appeared, and the appearance of this technology has also broken the restrictions of previous websites, making network search resources faster and easier to be accepted and remembered.
