The Memory Buffer Register (MBR)

is a hardware memory device which denotes the location of the current instruction being executed.

is a group of electrical circuits (hardware), that performs the intent of instructions fetched from memory.

contains the address of the memory location that is to be read from or stored into.

contains a copy of the designated memory location specified by the MAR after a "read" or the new contents of the memory prior to a "write".

Memory management is :

not used in modern operating system

replaced with virtual memory on current systems

not used on multiprogramming systems

critical for even the simplest operating systems

execute first the job that has been in the queue the longest

executes first the job that last entered the queue

executes first the job that first entered the queue

execute first the job that has been in the queue the longest

executes first the job with the least processor needs

Suppose that you have a the maintenance package identifies several possible field replaceable units (FRUs) that will resolve the problem. What should you do after turning the power off?

Replace all of the indicated FRUs at once and return the machine to the customer if the problem is resolved

Replace the indicated parts, one at a time in the recommended sequence, until the problem is resolved; return unused FRUs to stock

Replace all of the indicated FRUs at once and return the machine to the customer if the problem is resolved

Follow the same procedure as in ays replace the system board first if it is on the list of possible FRUs If multiple FRUs are indicated, then software is the most likely source of the problem

is a sign of an efficient system

is taking page frames from other working sets

is taking larger disk spaces for pages paged out

Which of the following refers to the associative memory?
