Answer 1

The Map function takes a series of key/value pairs, processes each, and generates zero or more output key/value pairs.

Answer 2

Answer:

The map function takes a series of key/values pairs, which processes each data and generates no output or multiple output. In the map unction, each data to be stored are identified by a corresponding value of key.

Explanation:

In a map function storage process, the data items which are stored are not stored in a sequential manner, like the arrays. In a map function any particular data cannot be retrieved by any positional values, or index positions. In order to retrieve values, the corresponding key value is needed.
