I have a SQL field (Integer type), and in this example, it holds the value "1024". 

In looking at my documentation for the DB schema, this field can be parsed such that:

"Bit 0 means Default"
"Bit 1 means Opposite of bit 0"
"Bit 2 means Verified"
"Bit 3 means Duplicate"
"Bit 4 means Manual"
...

And it goes on all the way up to Bit 21.

I don't know what the Bit thing means or how it relates to the Integer value. I'm not even really sure how to google this (if that makes sense), so I'm hoping SO can help (or help me with the wording to use for Googling).

Thanks.

(added SQL-Server as a tag, but not sure if it's relevant here or not)
