Q2) Describe a network address including its addressing scheme, formats and alternate names.
Answer: Network addresses follow a hierarchical addressing scheme and can be assigned through operating system software. They are hierarchical because they contain subsets of data that incrementally narrow down the location of a node, just as your home address is hierarchical because it provides a country, state, zip code, city, street, house number, and person's name. Network layer address formats differ depending on which Network layer protocol the network uses. Network addresses are also called Network layer addresses, logical addresses, or virtual addresses.
