• URL Structure: A URL (Uniform Resource Locator) consists of several parts: scheme, domain, path, and query parameters.
🔗
• Scheme: Indicates the protocol used to access the resource (e.g., `http`, `https`, `ftp`). `https` is preferred for secure connections.
🌐
• Domain: The name of the website (e.g., `www.example.com`). It's composed of the domain name and the top-level domain (TLD).
📂
• Path: Specifies the location of a specific resource on the server (e.g., `/blog/article1`).
❓
• Query Parameters: Used to pass data to the server (e.g., `?search=keyword&page=2`). They consist of key-value pairs separated by `&`.
⚓
• Fragment Identifier: Points to a specific section within a page (e.g., `#section2`).
🔑
• URL Encoding: Special characters in URLs must be encoded to ensure proper transmission (e.g., spaces become `%20`).
