A small doubt

[<shyamk@eth.net>]

Good Morning/Evening  to all,
         I guess that it is standard in Unixes that :
0 : STDIN : keyborad
1 : STDOUT : monitor
2 : STDERR : error output device

If this much can be accepted , and this is true for Linux verssions , too ,
then how come I am given an error by my Linux machine for example :
[shyam @shyam shyam] cat < 0
Sample
^d

Can not open 0 : No file or directory
[shyam @shyam shyam]

The same occurs for 1 (STDOUT) also.

Please help .
