You can use double curly braces to reference variables
throughout the Postman user interface. For example,
to reference a variable named "username" in your request 
auth settings, you could use the following syntax with 
double curly braces around the name:

{{username}}

1-GLOBAL variables allow you to access data
between collections, requests, test scripts,
and environments. Global variables are
available throughout a workspace.

2-COLLECTION Only accessible within the same collection and
can not be accessed anywhere else
COLLECTION variables are available throughout 
the requests in a collection and are independent
of environments, so do not change based on the selected environment.
I use collection variables when
I use single environment like url details.
We can refer to the variable by using {{}}(double curly brace)
and  it can be used anywhere

3-ENVIRONMENT Variable , a variable that accessible
only when the environment is active 

Usually used for an app with multiple environment ,
we can use env variable to store variable with same name
and different value to store environment specific data 

for example : 

xxxNamed app has 3 environments with different
URL and Crendentials 

But all endpoints are exactly the same no matter what
environment you work on 

so we can create 3 environment called 
QA1 , QA2 , QA3 and run same set of request 
by selecting different environment.

Only one environment can be active at a time.


4-LOCAL variables are temporary, and only
accessible in your request scripts. 
Local variable values are scoped to a 
single request or collection run, and are no longer
available when the run is complete.


5-DATA variables come from external CSV and JSON files
to define data sets you can use when running collections
via the Collection Runner.
