Describe and diagram the different parts of a common url.
A common URL (Uniform Resource Locator) consists of several parts that provide specific information about a resource's location on the internet. Here is a breakdown of the different parts of a common URL along with a diagram:
1. Protocol: The protocol specifies the rules and conventions that computers use to communicate with each other. The most common protocols are "http://" (Hypertext Transfer Protocol) and "https://" (Hypertext Transfer Protocol Secure).
2. Domain Name: The domain name is the address that identifies a website. It typically consists of two or more segments separated by periods (dots). For example, in the URL "https://www.example.com," "example.com" is the domain name.
3. Subdomain: A subdomain is an optional part that precedes the domain name. It can provide additional context or specify a particular section of a website. For instance, in the URL "https://blog.example.com," "blog" is the subdomain.
4. Top-Level Domain (TLD): The TLD represents the highest level in the hierarchical domain naming system. It indicates the type or country of the website. Common TLDs include ".com" (commercial), ".org" (organization), ".net" (network), or country-specific codes like ".uk" (United Kingdom). In the example URL "https://www.example.com," ".com" is the TLD.
5. Path: The path indicates the specific location or directory where the resource (such as a webpage or file) is stored on the server. It follows the domain name and is typically separated by forward slashes. For instance, in the URL "https://www.example.com/blog/post," "/blog/post" represents the path.
6. Query Parameters: Query parameters are optional and appear after a question mark "?" in the URL. They provide additional information to the server or script that processes the request. Query parameters are typically in the format of key-value pairs, separated by ampersands "&". For example, in the URL "https://www.example.com/search?q=keyword&page=1," "?q=keyword&page=1" is the query parameter.
7. Fragment Identifier: The fragment identifier, often preceded by a hash "#" sign, specifies a specific section within a document. It is used for direct navigation to anchor points or sections on a webpage. For instance, in the URL "https://www.example.com/page#section2," "#section2" is the fragment identifier.

Fragment Identifier
A common URL, or Uniform Resource Locator, is the address that is used to access resources on the internet. It consists of several parts, each serving a specific purpose. Here is a breakdown of the different parts of a typical URL:
1. Protocol: The protocol indicates the method used to access the resource. It usually appears at the beginning of the URL and is followed by a colon and two forward slashes. The most common protocols are "http://" for Hypertext Transfer Protocol and "https://" for secure Hypertext Transfer Protocol.
2. Domain: The domain represents the name of the website or server where the resource is hosted. It typically consists of three parts: the subdomain (optional), the domain name, and the top-level domain. For example, in the URL "www.example.com," "www" is the subdomain, "example" is the domain name, and ".com" is the top-level domain.
3. Path: The path specifies the specific location or file on the server that you want to access. It comes after the domain and is separated from it by a forward slash. For example, in the URL "www.example.com/path/to/resource," "/path/to/resource" is the path.
4. Parameters: Parameters are used to pass additional information to the server. They are separated from the path by a question mark and can be multiple key-value pairs. Each key-value pair is separated by an ampersand. For example, in the URL "www.example.com/page?param1=value1¶m2=value2," "param1=value1" and "param2=value2" are the parameters.
5. Fragment identifier: The fragment identifier, also known as the anchor, refers to a specific section within a webpage. It is usually denoted with a hash symbol (#) and appears at the end of the URL. However, it does not get sent to the server and is processed by the browser instead. For example, in the URL "www.example.com/page#section1," "#section1" is the fragment identifier.
Here is a diagram representing the different parts of a common URL:
```

└───────┴─┬───────┴─┬──────────────┴────────┬────┴─────┬───┘

Note that not all parts are present in every URL. Some URLs might not require a subdomain, or they may include additional subfolders in the path. Similarly, parameters and fragment identifiers are optional and depend on the specific resource being accessed.
A URL (Uniform Resource Locator) is the address used to access a web page or any other resource on the internet. A common URL consists of several parts, each serving a specific purpose. Let's break down the different parts of a typical URL and explain what they represent:
1. Protocol: The protocol specifies the rules and procedures for communication between clients (browsers) and servers. It is usually denoted at the beginning of a URL, followed by a colon and two forward slashes. The most common protocols are "http://" for regular web pages and "https://" for secure web pages.
2. Domain Name: The domain name identifies the specific website or web resource you are trying to access. It is typically a human-readable name and often starts with "www." For example, in the URL "https://www.example.com/page", the domain name is "example.com". The domain name is followed by a dot extension, also known as the top-level domain (TLD). Common TLDs include ".com" (commercial), ".org" (organization), ".net" (network), and country-specific TLDs like ".us" (United States) or ".uk" (United Kingdom).
3. Path: The path represents the specific location or file within the website or web resource. It comes after the domain name and is separated by a forward slash "/". It can be a directory or a specific file. For example, in the URL "https://www.example.com/page", the path is "/page". If there are additional directories within the path, they are separated by slashes. For instance, "/folder1/folder2/page" would indicate a file named "page" located inside "folder2", itself located inside "folder1".
4. Parameters: Parameters are optional parts of a URL that provide additional information to the server. They follow the path and are separated by a question mark "?". Parameters are usually in the form "key=value" and multiple parameters are separated by an ampersand "&". For example, in the URL "https://www.example.com/page?key1=value1&key2=value2", "key1=value1" and "key2=value2" are parameters.
To diagram a typical URL:
Protocol://DomainName/Path?Parameter1=Value1&Parameter2=Value2
For example:
https://www.example.com/page?key1=value1&key2=value2
It's worth noting that URLs may vary based on the specific website or web resource, and some URLs may contain additional parts or variations depending on the use case.
