Explain null resource in the context of Terraform.

1.	Explain null resource in the context of Terraform.
Answer» The NULL resource is a resource that lets you SET up provisioners that aren't directly linked to any current resource. Because a null resource behaves like any other resource, you can configure provisioners, CONNECTION details, and other meta-parameters just like any other resource. This gives you more precise control over when provisioners execute in the dependency GRAPH.
