What is URL is actually an acronym whose full forum is “ Uniform Resource Locator ”. You can think of this as a reference (or an address) that refers to a unique resource on the Internet.
If you are new to the Internet, then you must have found this word URL very confusing. You might have heard about it many times here and there but you will not know much about it. Then in today’s article you will get to know its complete information.
Then what is the delay, let’s start and know what exactly this URL is and how it works.
What is URL – What is URL in English
A URL is a formatted text string that is used to find a network resource in web browsers , email clients or any other software. Network Resources can be any files such as Web Pages, Text Documents, Graphics or Programs .
Since those resources are represented by the URL and also the URL vertical, all these are handled by the web server. In such a situation, it depends on the owner of that web server how to handle these resources and the URL associated with it.
How many parts does a URL have?
Any URL has three parts
- Protocol Designation
- Host Name or Address
- File or Resource Location
Special characters are used to separate all these substrings. Whose format is something like this.
protocol :// host / location
URL Protocol Substrings
This type of protocol defines the network protocol so that a network resource can be easily accessed. These strings are often short names followed by three special characters ” :// ” This is a typical name conversion that denotes the Protocol definition.
Typical Protocols that are used are such as HTTP (http://) , FTP (ftp://) etc.
URL Host Substrings
With the help of Host Substring, any destination computer or network device can be identified. Hosts come only from the standard Internet database such as DNS and which we also know by the name of IP addresses. The hostname of many websites does not represent just a single computer, but it shows that it is a group of WebServers.
URL Location Substrings
Location Substring shows the path of a particular network which is present in that host. Resouces mainly resides in a host directory or folder.
What is the full form of URL?
The full form of URL is Uniform Resource Locator.
About Uniform Resource Locators Tim Berners-Lee was the first to bring this technology to the world. Who first brought this idea in front of everyone that such an organization which provides unique locational address to all the web pages.
So that they can be easily searched online. After creating HTML, many pages were created in the World Wide Web using standard language and hyperlinks with it. After that both of them were linked together. Due to which the internet got bigger day by day.
How does URL work?
The URL has been designed in such a way that it is easy for people to remember it. But the computer needs information to identify the right website so that it can easily locate the right website.
Our browser uses its IP to browse a webpage. IP which we also know as Internet Protocol. This is a series of IP numbers which looks something like this 220.127.116.11
Just imagine how difficult it would be if we had to remember all the websites by their IP address. And the wants of internet are probably not as many as they are in this world today. Let me tell you this thing that not all websites have static URLs.
Some keep changing from time to time, due to which it is very difficult to reach them. That’s why we use URLs which are always the same and which are easy to remember.
When we type the URL of a website, then the browser then DNS which is also called as Domain Name Server and with the help of this it changes that URL to its corresponding IP. And with the help of which the browser reaches that website.
Types of URLs
By the way, there are many types of URLs and many different terms are used for them. I have told about some types here.
1. Messy : These are those types of URLs in which there are many numbers and letters from which some oraganization sense comes. For example, ‘ http://www.example.com/woeiruwoei909305820580 ‘. Generally these URLs are generated by the computer which creates thousands of web pages for the same domain name.
2. Dynamic : These URLs have also originated from the same place where Messy URLs have come. These URLs are the end result of a database query that provides content output in the result of any query. These also look like Messy URLs in which characters like ?,&,%,+,=,$ appear. They are mainly used in the websites used by the consumer such as any shopping, traveling websites in which the users keep changing their queries frequently so that the answers also keep changing.
3. Static : These are the exact opposite of any dynamic URL. This URL is completely hard wired with the webpage’s HTML coding. This URL never changes, no matter what the user is requesting.
4. Obfuscated : This is a very dangerous URL which is used in Phishing Scam. As its name suggests, they are hidden. Which is used very cleverly so that it looks completely original. So when a user clicks it, then he redirects them to Malicious Website.
Why are characters not used in URLs?
We all must know that Space is not used in URL. But we should also know that according to RFC 1738 only alphanumeric characters and other characters like !,$,-,_,*,’,() are used in the string of URL. And if any other characters are used then it has to be encoded.
Absolute versus Relative URLs
Absolute URLs are called in which all the mentioned sub strings are used. But in some cases only some or one location element is used, such URL is called Relative URL . Relative URLs are used in web servers and web pages as shortcuts to reduce the length of URL strings.
For example, the link of the same website is written in the format of Relative URL and Absolute URL.
The best thing that happens in this is that with the help of a web server, all the missing protocols and host information are automatically filled. But keep in mind that relative URLs can be used only in those places where Host and Protocol Information can already be established.
What is URL Shortening
If we talk about Standard URL of any modern website, then we will know that these are very long strings. And how difficult it is to share strings of such long URLs.
Due to which many companies have created many such online translators, with the help of which a full URL can be shortened very much and can be used wherever they want. There are some popular url shorteners like t.co (for Twitter) and lnkd.in (for LinkedIn) .
Along with this, there are many URL shortening services such as bit.ly and goo.gl, with the help of which people around the world are shortening their URLs for free. Along with this, many URL Shortening Services are also offering click statistics. Moreover, some even check the malicious URL in the suspicious Internet domain and inform the user.
What are Secure URLs
Secure URLs are websites that start with https:// The URL of such a website is called Secure Url. Which means that even if you enter your personal information in such a website, it gets encrypted before it is transmitted and it is not so easy for any hacker to read it. If you want to know in details, then read what is SSL .
For the same reason, if a website asks you about your personal things like your banking details etc. then first of all do not forget to check whether it is a secure URL or not. And such a website should use some Security Protocol in its URL so that the consumer’s information is not misused. I advise you to take special care of all these things before giving any personal information.
I think by now you must have understood very well how important a sitemap is , if you do not want to miss any page of your website, then you have to take care that those crawlers do not miss any page.
You can also add additional metadata such as Change Frequency and Priority. With this you can also create Sitemap for video and image. And once you have created a Sitemap, do not forget to validate it and notify Search Engines.
How does the URL appear?
In common form of a URL, a URL begins with “http://” or “https://”, then is followed by “www,” and then the name of the website is used.
Why is URL so important?
URL is actually the online name of any resource. In such a situation, if anyone wants to know about your or someone else’s online resource, then he should know about the URL of your resource.
Where do we see the URL on our computer?
Often you will see a URL displayed on the address bar of your computer’s browser. A typical URL format is something like this: https://www.cessind.org
