Connection Strings

Could you help me understand what this piece of code does in simple English? This is a beginner. Thank you in advance.\[code\]<connectionStrings><add name="BalloonShopConnection" connectionString="Server=(local)\Sql?Express; Database=BalloonShop; User=balloonshop; Password=ecommerce" ?providerName="System.Data.SqlClient" /><remove name="LocalSqlServer"/><add name="LocalSqlServer" connectionString="Server=(local)\SqlExpress;?Database=BalloonShop; User=balloonshop; Password=ecommerce" providerName=?"System.Data.SqlClient" /></connectionStrings>\[/code\]This is from a tutorial. I covered everything up to first half of the book but this seems strange.
