Previously in this course, we've introduced wearables as a temporary storage container for objects.
And this section, you'll learn more about wearables and all the rules for using them after completing
this section.
You'll be able to explain the purpose of wearables, describes the rules for using wearables, create
management, use wearables and write mathematical calculations and display information by using wearables.
Let's get started in windows for Shell.
Wearables are temporary storage containers for raw objects.
Each wearable can contain one or more objects.
A wearable that contains more than one object is typically called an array.
Please know that in some programming languages, array, wearables and collections of objects have important
differences.
Those differences are very minor in Windows Power Shell and the terms, array and collection are sometimes
used interchangeably.
Now the shelf stores wearables.
In the four years drive variable, you can use the drive to change wearables, view them and remove
them.
The show also provides a set of commands that manage wearables to sale list just from GURT Command Dash
known wearable.
Most Windows power show users do not use those commands because the show also supports ad hoc wearable
creation and management.
You'll see the ad hoc technique in this lesson.
So every time that you start on your Windows potential session, it has its own drive wearable.
The drive is populated with several built in wearables that control different parts of the shelves behavior.
Some of those built in wearables are constants, meaning they are a read-only and can not be changed.
For example, they are built in dollar shell ideal.
Wearable is the read-only.
The billion dollar verbose preference is not redundant and can be changed.
Variables are a scoreboard.
That means that they can be created inside a specific in-memory container.
And they exist only as long as they are contained or exists.
Wearables created as a command prompt or stored in the global school and exist only until the current
shell session is closed.
Wearables created in this group exist only until this group finishes Saron and wearables created inside
a function.
Exist only until that function finishes Sorano.
