Newb Question, Global Variables

[gep13]

Hello,

As a simple example:

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not Session("RandomWord") Is Nothing Then
            Me.Label1.Text = Session("RandomWord").ToString()
        End If
    End Sub

    Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Session("RandomWord") = Me.TextBox1.Text
    End Sub

I'm sorry, I need more of an explanation. Can you explain session variables and then with my code show me how to implement it so I can understand it better?
