1.	What do you understand about Terraform modules?
Answer» A Terraform module is a single directory containing Terraform CONFIGURATION files. Even a simple arrangement with a single directory having one or more files can be referred to as a module. The files have the extension .tf. This directory is referred to as the root module when Terraform commands are RUN directly from it. Terraform commands will only use the configuration files in one location: the current working directory. Your configuration, on the other hand, can employ module blocks to call modules from other directories. When Terraform comes across a module block, it loads and processes the configuration files for that module. A module that is CALLED by another configuration is FREQUENTLY referred to as that configuration's "CHILD module."
