Here's why:
* Compound nouns are formed by combining two or more words to create a new meaning. They can be written as one word (e.g., "firefly"), two words (e.g., "high school"), or hyphenated (e.g., "well-being").
* "Network" is a single word that has its own distinct meaning. It refers to a group of interconnected people or things.
Example of a compound noun: "Network administrator" is a compound noun because it combines the words "network" and "administrator" to refer to a specific job role.
