I have googled enough but could not figure out what the bracket () means. Also, I see some syntax as movl 8(%ebp), %eax

Could some someone suggest me some good reference? I have not been able to find any in the top 20 results from Google.

%eax is register EAX; (%eax) is the memory location whose address is contained in the register EAX; 8(%eax) is the memory location whose address is the value of EAX plus 8.
