What Is a URL(Uniform Resource Locator)? types, Features, And Structure

A URL Full Form is a Uniform Resource Locator. it is a reference or address used to access resources on the internet. It serves as a standardized way to locate and retrieve information on the web.

How do URLs work?

URLs, or Uniform Resource Locators, serve as web addresses to locate resources on the Internet. When users enter a URL on a web browser, the browser communicates with a DNS server to translate the domain into an IP address. Using the specified protocol, the browser then connects to the server, retrieves the requested content (webpage, image, video, etc.), and displays it to the user, providing access to the vast expanse of the World Wide Web.

Types Of a URL

Web Page URLs: These URLs are used to access specific web pages on the internet. They often include a combination of the protocol (http or https), domain name, path, and sometimes query parameters. Example: https://simiservice.com/category/watches/

File URLs: File URLs are used to reference local files on a system. They start with the file:// scheme followed by the path to the local file. These are often used for accessing files stored on a user’s computer. Example: file:///path/to/local/file.txt

FTP URLs: FTP URLs are used to access resources on a server using the File Transfer Protocol (FTP). They typically include the ftp scheme, the host name, and the path to the resource on the server. Example: ftp://ftp.example.com/files

Email URLs: Email URLs are used to create links that, when clicked, open the user’s default email client with a pre-filled email address. They use the mailto scheme followed by the email address. Example: mailto:user@example.com

Tel URLs: Tel URLs are used to create links that initiate a phone call when clicked on supported devices. They use the tel scheme followed by the telephone number. Example: tel:+1234567890

Data URLs: Data URLs are used to embed data directly into web pages. They start with the data: scheme followed by the MIME type and the data itself. Commonly used for embedding images or other small resources. Example: data:image/png;base64,iVB...

Protocol or Scheme: The scheme indicates the protocol used to access the resource. Common schemes include http, https, ftp, mailto, etc. The protocol is followed by a colon and two forward slashes (e.g., https://).

SubDomain Name: A subdomain is a subdivision of a larger domain within the Domain Name System (DNS) hierarchy. It is a way to organize and structure websites or online services under a primary domain.

Host Name or Domain Name: The hostname or domain name identifies the server or network location where the resource is hosted. It can be a human-readable domain name (e.g., www.example.com) or an IP address (e.g., 192.168.1.1). The hostname is immediately after the protocol and is followed by an optional port number. Example: www.example.com

Port Number: The port number is optional and specifies the communication endpoint on the host. The default ports are often omitted (e.g., http uses port 80, https uses port 443).

Path: The path indicates the specific resource or location on the server. It may include subdirectories and file names. Example: /path/to/resource

Query Parameters: Query Parameters: Query parameters provide additional information to the server, usually in the form of key-value pairs. They are separated from the rest of the URL by a question mark (?) and are joined with ampersands (&). Example: ?id=123&name=example

Fragment: The fragment identifies a specific section or anchor within the resource, often used in HTML documents. It is separated from the rest of the URL by a hash (#) symbol.

What is URL shorteners

URL shorteners are online tools or services that take a long URL and create a shortened version that redirects to the original URL. The primary purpose of URL shortening is to create more manageable and shareable links, especially in situations where character count is limited or for aesthetic reasons. URL shorteners work by assigning a unique identifier to the original URL and creating a shorter alias.

What is URL Redirect?

URL redirect, also known as URL forwarding, is a technique used to make a web page or website available under multiple URLs. In a URL redirect, when a user attempts to access a particular URL, they are automatically redirected to another URL.
