Language ID in SQL Server

Usually, we used to here the messages like problem with 1033 folder or similar kind of problem. What's this 1033 folder?
 
      It's nothing but "A specification for the SQL Server language installed in the machine"
 
1033 - In windows term language, it's english language. You can get the language supported by a particular version or installation in SQL Server by executing the below query,

                       select * from syslanguages
 
Cheers,
