[Savi Jaglan]

I am a begginer, trying to learn django and django rest framework. i have few questions. Don't know whether they are silly to ask or not. please bear with me.

1. what is the simple definition or api and microservice. what's the differnce between these two?

2. why we use api?
3. how to know it's an api?
