signed can be a minus value (- sign) unsigned is positive only

Think of it like this, it is a data type modifier. Signed means exactly that, the data type is signed (having a negative value (-9 for example), or can have a negative value), where unsigned, again means exactly what it implies (a positive only value (9 for example)). It's an honestly easy concept, just you gotta remember it ^_^
