Answer 1

Google Tag Manager (GTM) is a tag management tool. Google Analytics, Google Adwords, Remarketing, Hotjar, Adobe are some of the tags that GTM manages and much more..

GTM is a container script that you add to website once. Any further modifications for tracking can be done within GTM without playing with website code any further.

GTM is just a way to embed tracking code in the website, even after embedding it does not track or collect data till you add Google Analytics id in its configuration.

GA is reporting and analysis tool and GTM is more like GUI driven tech tool targeted at non-developers.
