Global variables are akin to universally accessible containers in PowerApps, holding various data types like text, numbers, tables, records, or booleans. These variables are accessible across all screens within a PowerApps app. For instance, creating a global variable is simple:
Set(global_variable, “Example”)
In this example, global_variable represents the variable name, and "Example" is its assigned value.

Context variables in PowerApps are similar to method parameters in traditional programming. The scope of these variables is limited to the screen as they are defined. To declare a context variable, use:
UpdateContext({context_variable: ”Example”})
Context_variable is the variable name; the value is shown by "Example." These variables are defined within curly braces and support various data types.
Collections are akin to tables or arrays in PowerApps, capable of storing multiple rows of data. They are application-wide variables. Moreover, collections are created using:
Collect(collect_variable, “Example”)
collect_variable here is the collection's name, and "Example" is its initial value.
