You’ve probably come across the terms URL and URI. They might sound like technical jargon, but fear not – understanding their differences is helpful, especially if you’re embarking on an online business journey or delving into web design and development.
In this comprehensive guide, we’ll demystify the technical jargon of URIs and URLs, unraveling their definitions, syntax, and most importantly, their key disparities. So, whether you’re a budding entrepreneur or a seasoned website administrator, this article is your compass to navigate the vast landscape of web resources and the differences between URI vs URL.

What Are URIs? Syntax + Example
Before we dive into the nitty-gritty of URIs, let’s break down the acronym. URI stands for Uniform Resource Identifier, which essentially serves as a unique string of characters used to identify and locate resources on the web. Think of it as a digital address that helps your browser locate and retrieve specific resources on the vast expanse of the internet. URIs come in two flavors: URLs and URNs (Uniform Resource Names). URLs, which we’ll explore in detail later, are the more commonly used subset of URIs.
The syntax of a URI is surprisingly simple, it typically comprises two main components: the scheme and the path. The scheme specifies the protocol or method to access the resource, while the path denotes the specific location within the resource. Here’s a breakdown of a typical URI:
scheme:[//authority]path[?query][#fragment]Let’s decipher this with an example. Imagine you’re looking for information on the benefits of SSD storage. The URI might look like this:
https://www.mcloud9.co.za/blog/what-is-ssd-storage/?utm_source=blog&utm_medium=article#pros-of-ssds
In this example, https is the scheme, www.mcloud9.co.za is the authority or domain name, /blog/what-is-ssd-storage is the path to the resource. This is followed by utm_source=blog&utm_medium=article which is the query string, and pros-of-ssds which is the fragment. Together, they create a unique URI that identifies the exact webpage you’re seeking. Each component serves a specific purpose in guiding your browser to the desired information.
What Are URLs? Syntax + Example
Now, let’s shift our focus to URLs, or Uniform Resource Locators. Think of URLs as a subset of URIs, designed specifically to pinpoint the location of a resource on the internet. URLs are the digital addresses you type into your browser’s address bar when you’re wanting to explore a new webpage or delve into the digital cosmos. As of 2022, there are approximately 370 million registered domain names worldwide. Each of these domain names corresponds to a URL, serving as a distinct address for accessing online resources.
The syntax of a URL closely mirrors that of a URI, with a few key differences. It encompasses the scheme, domain name, and sometimes the path. For example, suppose you’re a passionate food blogger aiming to share your culinary adventures. Your website’s homepage URL might look something like this:
https://www.mcloud9.co.za
In this case, https is the scheme, www.mcloud9.co.za is the authority or domain name, and there’s no path, query, or fragment. This URL elegantly directs users to the front door of your virtual culinary haven.

URI vs URL – The Key Difference Between URI and URL
At this point, you might be wondering, “Aren’t URIs and URLs essentially the same?” While they share similarities, there’s a pivotal distinction that sets them apart. A URL is a specific type of URI that not only identifies a resource but also provides its network location or primary access mechanism. In essence, all URLs are URIs, but not all URIs are URLs.
Think of it this way: a URL is like a GPS coordinate with precise directions, while a URI is a broader category encompassing different types of resource identifiers. URIs include URLs, but they can also comprise Uniform Resource Names (URNs) that focus solely on identifying resources without indicating their location.
In the digital realm, a URL is like a destination you can directly navigate to, whereas a URI is a signpost that points to both destinations and general areas.
FAQ for URI vs URL
What is the difference between URI and URL?
URI stands for Uniform Resource Identifier, which is a sequence of characters that identifies a name or location of a resource. URL stands for Uniform Resource Locator, which is a type of URI that specifies the address or destination of a resource.
Can URI and URL be used interchangeably?
No, a URL and a URI are not exactly the same thing. URL is a subset of URI, and while all URLs are URIs, not all URIs are URLs.
What is the difference between URL and URN?
URN stands for Uniform Resource Name, which is a type of URI that identifies a resource by its name rather than its location. In contrast, a URL specifies both the name and the location of the resource.
How is a URL structured?
A URL typically consists of several parts: a protocol (such as HTTP or FTP), a domain name or IP address, a path, and possibly additional parameters or fragments.
What is the purpose of a URL?
The purpose of a URL is to provide a unique address or identifier that can be used to locate and access a specific resource on the internet.
How is a URI different from a web page?
A URI is a generic term that can be used to identify any resource, not just web pages. A web page is a specific type of resource that can be identified and accessed using a URL.
Can a URI contain any characters?
Yes, a URI can contain a sequence of characters, including letters, numbers, special characters, and even non-ASCII characters. However, certain special characters may need to be encoded to ensure proper interpretation by web browsers.
What is the role of schemes in a URI?
URI schemes help determine how the URI should be interpreted and processed. For example, the “http://” scheme indicates that the resource should be accessed using the Hypertext Transfer Protocol.
What is the difference between a URL and a URN?
The main difference is that a URL specifies the destination of a resource, while a URN identifies the resource by its name. A URL can be seen as a subgroup of URI that specifies the location, while a URN is a type of URI that identifies.
Why does a URL contain a colon followed by a protocol?
The colon followed by a protocol in a URL indicates the type of URI scheme that should be used to access the resource. For example, “http://” indicates the Hypertext Transfer Protocol.
In Conclusion
As you embark on your digital journey, whether as an entrepreneur establishing an online presence or a web designer crafting captivating user experiences, understanding the nuances between URIs and URLs is a valuable asset. Remember, URIs encompass all types of resource identifiers, while URLs are a subset specifically designed to guide you to the doorstep of your desired online destination.
