Final answer:
In a URL, the '.com' portion is called the top-level domain (TLD). The TLD indicates the nature of the website, with .edu for educational, .gov for government, .org for nonprofit organizations, and .com for commercial entities.
Step-by-step explanation:
In the URL "example.com", ".com" is known as the top-level domain (TLD). The TLD indicates the type of entity that owns the domain. For example:
- URLs with .edu are typically owned by educational institutions like colleges or universities.
- URLs with .gov are affiliated with the federal government.
- URLs with .org are commonly held by nonprofit organizations.
