I have a little question regarding x86 assembly:

On any 386 instruction set reference, the description about DIV (Unsigned Divide) are as follows:

"... DIV divides the EDX:EAX with r/m32 and stores the result on the EAX register, and the remainder on the EDX register..."

But I don't understand the 'EDX:EAX' part, what it means?

Thanks in advance (thumbsup)
