Why IS it essential to use symbolic representation of machine instructions?

• It makes machine instructions more human-readable and understandable

• It reduces the overall complexity of computer systems and user programs

• It minimizes the need for memory storage for the user programs

• It enables fastest execution of high level language instructions

The hardware mechanism that allows a device to notify the CPU is called

• polling

• interrupt

• driver

• controlling

What is a branch instruction?

• The instructions that are used to divide a program into multiple subprograms

• The instructions that have as one of its operands the address of the next instruction to be executed

• The instructions that are used to pause the program

• The instructions that are used to return to the beginning of the program

What is the role of the control unit in a processor?

• The control unit’s primary role is to perform arithmetic and logical operations within the processor, orchestrating the manipulation of data

• The control unit only manages the flow of data between the CPU and external devices and does not play a significant role in executing instructions

• The control unit is solely responsible for managing the flow of instructions from secondary storage to RAM and does not have a role in the internal operation of the CPU

• The control unit in a processor directs and coordinates the

How do data registers and address registers differ in some computer systems?

• Address registers can be employed in calculating operand addresses, while data registers hold data

• Data registers are only used for stack-related operations

• Data registers are used for indexed addressing while address registers are used for data storage

• Address registers are reserved for segmented addressing while data registers are general-purpose

What is the main benefit of using ARM processors over other processors?

• Low cost and low power consumption

• Higher degree of multi-tasking

• Lower error or glitches

• Efficient memory management
