URL Global Resource Locator n[Computer Internet].

URL (Uniform Resource Locator) Chinese name is Global Resource Locator, also translated as Universal Resource Locator, which is an address that can independently identify the location of computers, directories or files on the Internet, and can also specify communication protocols, such as gopher, http, etc. URLs allow all resources on the Internet to find their location in this way.

Introduction to URLs.

If you want to link to a web page in www (global information network), you need to give the browser an address, and the function of URL here is to tell the browser that a resource is in that location, in short, usually we enter ** in IE or Netscape browser is one of the URLs.

HTTP (Hypertext Transfer Protocol) is the main communication method between the server and the browser in WWW, and in order to allow the browser to find the location of the data correctly on the Internet, the browser is used to determine the location of a resource in the form of URL. Usually the URL does not necessarily point to a super ** file, it can also be a service on some kind of network, such as ftp, gopher, etc.

The format of the URL.

URLs are separated by : , for example

It refers to the address of the server, where www is the world wide web, and dreye is the name of the site, and com refers to the domain type, which needs to be used inpoints separated; It is usually followed by the country (e.g. TW in Taiwan) to form the most basic URL format: protocol:

The type of link. Station name. Domain type.

Country. In terms of protocol (transmission or communication protocol), there are different services such as http, ftp, telnet, gopher, etc., and there are many classifications of domain types, such as com is a commercial organization, edu is an educational institution, gov is **, mil is the military**, net is a network service company, etc.

Password@subdomain. Domain name. Top-level domains:

Port number directory file name. File suffix? Parameter=Value flag.

Extended Materials. Classification: Absolute URLs and Relative URLs

The absolute URL shows the full path to the file, which means that the location of the absolute URL itself has nothing to do with the location of the actual file being referenced.

Relative URLs describe the location of the destination folder based on the location of the folder containing the URL itself. If the target file is in the same directory as the current page (i.e. the page containing the URL), then the relative URL of the file is just the file name and extension.

2.If you want to reference a file in a directory higher in the file hierarchy, use two periods and a slash. Two periods and a slash can be combined and reused to refer to any file on the hard disk where the current file is located, 3

In general, for files on the same server, relative URLs should always be used, they are easier to enter, and more convenient when moving pages from the local system to the server, as long as the relative position of each file remains the same, the link is still valid.

URL is a unified resource locator, a concise representation of the location and access method of resources that can be obtained from the Internet of Mutual Sails, and is the address of standard resources on the Internet.

Every file on the internet has a unique URL that contains information that indicates the location of the file and what the browser should do with it.
