A web address, also known as a URL (Uniform Resource Locator), is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. URL stands for Uniform Resource Locator and is the string of text that a user enters into a web browser to access a particular web page or resource.
Components of a Web Address
Understanding the structure of a web address is crucial for efficient web navigation and management.
Protocol
The protocol specifies the method of data transfer. Common protocols include:
- HTTP (Hypertext Transfer Protocol): Used for standard web pages.
- HTTPS (Hypertext Transfer Protocol Secure): A secure version of HTTP.
- FTP (File Transfer Protocol): Used for transferring files.
Domain Name
The domain name is the address of the website and usually consists of several parts:
- Top-Level Domain (TLD): For example,
.com
,.org
,.net
. - Second-Level Domain: The name registered by the user, e.g.,
example
inexample.com
. - Subdomain: A subdivision of the main domain, for example,
subdomain.example.com
.
Path
The path specifies the exact resource or page on the website. For example, in the URL http://example.com/articles/technology
, /articles/technology
is the path.
Query Parameters
Query parameters are a way to pass information to the server. They are usually found after the ?
in a URL. For example, http://example.com/search?q=web+address
.
Fragment
The fragment (or anchor) starts with a #
and allows users to jump to a specific part of a web page. For example, http://example.com/articles#section2
.
Examples of Web Addresses

http://example.com/articles#section2
Historical Context
The concept of URLs was created in 1994 by Tim Berners-Lee, the inventor of the World Wide Web. He designed URLs as a simple way for users to access web resources without needing complex technical knowledge.
Applicability in Modern Digital Landscape
- Web Development: Understanding URLs is vital for web developers for proper site navigation and resource linking.
- SEO: URLs play a significant role in search engine optimization (SEO). Clean and descriptive URLs can improve search rankings.
- Cybersecurity: HTTPS ensures secure interactions, protecting sensitive information against cyber threats.
Related Terms
