NER is a process where an algorithm takes a string of text (sentence or paragraph) as input and identifies relevant nouns (people, places, and organizations) that are mentioned in that string.

In Parts of Speech (POS) you label each of the words (often called tokens) of a sentence or many sentences with grammatical descriptions, such as noun, adjective, adverb. These tags identify the composition of the texts.
