Having some confusion

I am new to asp.net and trying to learn the basics. I am reading a book for asp. Whenever i choose some web control from the toolbox such as a text box there is a <select/> tag that is attached in the source with that control tag such as
 
</select><asp:TextBox ID="TextBox1" runat="server" Width="40px"></asp:TextBox>
but in the book that i am reading it is saying that 
<asp:TextBox ID="txt" BackColor="Yellow" Text="Hello World"
ReadOnly="True" TextMode="MultiLine" Rows="5" runat="server" />
without any select
 Now if i remove this select tag the control disappear. 
Can someone please clarify for me as what is going on here?
thanks
