What is URL? What is it used for? What does URL do?

A URL (Unified Resource Locator) is an addressing system used to access resources (files, pages, images, etc.) on the internet. URLs provide information to web browsers to request a specific resource.

A URL consists of several different components, such as a protocol, domain name, domain extension, path, and file name. For example, the URL “https://www.google.com.tr/search?q=url&oq=url&aqs=chrome.0.0i131i433i512j46i131i433i512j46i131i433i512j69i60l2.784j0j7&sourceid=chrome&ie=UTF-8” redirects to a page with the query “q=url” on the path “/search” from the domain name “google.com.tr” using the HTTPS protocol.

The purpose of URLs is to uniquely identify and make resources accessible on the internet. URLs provide specific information to web browsers to request a resource. Internet users can access web pages, files, images, videos, and other resources using URLs.

URLs are one of the fundamental building blocks of web pages. Web pages are created using languages such as HTML, CSS, and JavaScript, and URLs indicate where these pages are stored. For example, the URL “https://tebilisim.com” redirects to the Wikipedia website. Web pages are connected to each other using URLs, allowing internet users to follow URLs as they navigate between different websites.

URLs are also essential for search engines. Search engines crawl URLs to understand the structure of websites. For example, a search engine may crawl all the URLs on a particular website to understand its structure. This helps search engines index websites and rank them correctly on results pages.

In conclusion, URLs provide a unique way for internet users to access web pages, files, images, and other resources. They are also essential for creating web pages and for search engines to crawl and understand websites. As the internet continues to evolve and grow, URLs continue to develop as well.

What is the difference between URL and domain?

The difference between URL (Unified Resource Locator) and domain is as follows:

A domain is the name of a website, such as “google.com” or “tebilisim.com“, representing a specific website.

A URL is the address of a specific resource (page, file, image, etc.) on a website. URLs provide information to web browsers to request a specific resource. For example, the URL “https://www.google.com/search?q=url” redirects to a page on the “google.com” domain with the path “/search” and the query “q=url”, using the HTTPS protocol.

Therefore, a domain is the address or name of a website, while a URL is the address of a specific resource on a website. Knowing the domain of a website may be sufficient to access the website, but knowing the URL may be necessary to access a specific page or resource.

Why is URL important?

URL (Unified Resource Locator) is a system of addresses used to access resources (pages, files, images, etc.) on the internet. The importance of URLs is as follows:

• Unique identification of resources: URLs allow each resource to be uniquely identified, enabling internet users to access the correct resources. To access a specific page or file on a website, one needs to use the URL.
• Sharing of resources: URLs facilitate the sharing of resources. Internet users can share a URL by copying and pasting it to show others a specific resource. For example, if you want to show an interesting article on a website to a friend, you only need to share the article’s URL.
• Interlinking of web pages: Web pages are interconnected through URLs. This allows internet users to follow URLs while navigating between different websites. Additionally, search engines use these links to understand the structure of websites and index them.
• Search engine optimization: URLs are scanned by search engines and used to understand the page structure of websites. Properly structuring URLs used on web pages helps search engines to better understand and index websites. Therefore, URLs are an important part of search engine optimization.
• Security: URLs are encrypted using secure protocols such as HTTPS. This allows internet users to transfer sensitive information (such as credit card details) securely. Certain parts of a URL (such as “https://” or “www”) also indicate certain security settings.

In conclusion, URLs provide many benefits to internet users, such as accessing resources, sharing resources, interlinking web pages, and search engine optimization. Therefore, URLs are one of the fundamental building blocks of the internet, and web developers place great importance on correctly structuring URLs.

A URL typically consists of the following five components:

1. Protocol: The protocol at the beginning of a URL is used to access a specific web server (HTTP, HTTPS, FTP, etc.). For example, the “https://” protocol is used to access a specific web server using the HTTPS protocol.
2. The domain name is the name of the website. For example, a domain name like “google.com” or “tebilisim.com” identifies a specific website.
3. Port Number: The port number is the port number used to access a specific web server. The standard HTTP port is 80, and the HTTPS port is 443. However, if a specific web server is using a different port number, this number should be specified in the URL.
4. Path: The path is the directory or path of the resource located on a specific web server. For example, a path like “/images/logo.png” identifies the “logo.png” file located in the “/images” directory.
5. Query String: The query string contains the parameters and values sent to a specific web server. The query string can be in a format like “?param1=value1&param2=value2”. This is used to make a specific query to a web page.

Each component of the URL provides the necessary information to access a specific web server. The components of a URL are read by web browsers and used to request a specific resource. Additionally, proper structuring of a URL helps search engines index websites and helps internet users access the correct resources.
