You can initialize an array that stores a set of items by assigning multiple values to a variable. All you need to do is separate each value with a comma. The following command would create an array of server names:

    $servers = "EX1","EX2","EX3"  

To create an empty hash table, use the following syntax:

    $hashtable = @{}  

Now that we have an empty hash table, we can add key-value pairs:

    $hashtable["server1"] = 1
    $hashtable["server2"] = 2
    $hashtable["server3"] = 3  

Notice in this example that we can assign a value based on a key name, not using an index number as we saw with a regular array. Alternatively, we can create this same object using a single command using the following syntax:

    $hashtable = @{server1 = 1; server2 ...
