Here's why:
* Purpose: Comments are used to explain the code, provide context, or indicate specific details. They are ignored by the compiler or interpreter, but are crucial for human understanding.
* Syntax: While parentheses are often used to group comments in certain programming languages, they aren't the defining factor. The specific syntax for comments varies widely between languages.
Example:
```python
This is a comment in Python, using the "#" symbol
print("Hello, World!") # This line prints a message to the console
```
Here, the lines starting with "#" are comments. They explain the code and are ignored when the program runs.
Note: The term "comment" is the most widely used and understood term. However, you might encounter other terms like "annotations," "remarks," or "notes" in specific contexts.
