I'm studying for an exam called Computer Fundamental, and started taking some previous exam but the given documents i had is way inadequate to solve all the question mentioned, like this one :
Which of the following is the correct combination of variousaddressing modes? Here, X1 is an address which is stored in a program counter. X2is an address part of an instruction which is addressed by X1.X3is an address in which an operand needed to execute an instruction is stored. X4is a value in an index register. (X2) means the contents of location X2.
I tried to google "Addressing mode" and came up with some resources that i can't understand.
Can someone recommend me some link where i can get to know more about addressing mode so that i can answer this question?
I'm sorry for the tag, can't find some thing like "address" or "addressing mode"
