Defunition
The abbreviation of the URL is the Uniform Resource Locator where it refers to certain characters, usually numbers, letters, and symbols, which go to an address on the world wide web (www).
It is used to identify the location of a file on the internet. Its use is not only to open a website, but also to download videos, images, hypertext pages, and others.
Using a URL is the same as when you want to open a file on a computer or laptop that can be done with just a double click. However, because you don’t have direct physical access to the file on the remote computer or in this case the website on the internet, you have to use it to find out where the file is.
Uniquely, the new URL was discovered by Tim Barnes-Lee in 1991 with the aim of making it easier for authors to create documents or articles and publish them to the world wide web.
Function
In addition to identifying website addresses, the function is to move users from one page to another using hyperlink media. Here’s a full explanation:
Can also be used for naming files stored on the website.
Identify documents, images, and files in other forms.
Can be used to address any web containing documents.
Make it easier for users to remember the addresses of documents that have been accessed.
URL type and structure
There are two kinds of URLs, namely Relative URLs which are used to address the document directory in the currently active domain and Absolute URLs, which are complete domains with file directories.
An example of a Relative URL is image.png. While the example of Absolute URL is https://dewaweb.com/images/images.png.
Actually, you don’t have to know the details of this structure when you access a site or document on the internet. However, knowing more about the URL structure is the same as when you want to know the telephone code in an area.
For example, the address https://pcsupport.about.com/od/driversites/tp/free-driver-updater-tools.htm is as follows:
http: shows the protocol whose function is to determine the type of server you are associated with
pcsupport: is the hostname for accessing the custom website
about: domain name
com: top level domain
/od/driversites/tp/: is the name of the folder you click on to open the document in question, as well as representing the directory for setting up a webpage or file.
free-driver-updater-tools.html: is the actual file designated.
But, for convenience, URLs can be divided into 3 specific parts, namely protocol, domain, and permalink.
In addition, there are also syntax rules used in programming languages. This rule can redirect you to a more specific site or directory of files. Errors in URLs are usually indicated by the appearance of a 404 error caused by a 400 status code error.
In addition, another convenience offered by this system is that you do not need to know the real address to access the IP address of the server. This is because the IP server address can function as a Homepage URL and an alternative link URL. You can use both to access a document directory.
