Hierarchical addressing is a method used to organize and identify data or resources in a structured manner. It breaks down information into levels, where each level represents a different category or subcategory. This approach is commonly used in computer networks, such as the Internet, where addresses are structured in a way that reflects their location within a larger system. In hierarchical addressing, each address consists of multiple parts, often separated by dots or slashes. For example, in a URL like "www.example.com/page," "www" is the subdomain, "example" is the domain, and "com" is the top-level domain. This structure helps in efficiently routing data and managing resources.
