certified Answers 2024/2025
Arithmetic Logic Unit (ALU) - correct answer AL and LU
Arithmetic Unit (AU) - correct answer performs a variety of arithmetic operations
Registers - correct answer A high speed holding device that the processor uses for
calculations and as pointer to data in the memory. The processor provides 16 registers
divided into four groups.
Logic Unit (LU) - correct answer compares information and makes decisions, performs
logical operations
Interrupters - correct answer CPU Can skip around and do stuff while it waits
Block Diagram of a Microcomputer - correct answer Clock, and processor

Bus - correct answer is a subsystem (a group of parallel wires) that transfers data
between components in a computer
Data Bus - correct answer transfers instructions and data between the memory and
CPU
, I/O Bus - correct answer transfers data between the I/O devices and CPU

Instruction Pointer (IP) - correct answer contains the address of the next instruction.
Instruction Fetch (IF) - correct answer The CPU fetches the next instruction and
increments the IP.
Instruction Decode (ID) - correct answer The control unit decodes the instruction's
function to determine what to do

Instructions Execution (IE) - correct answer The ALU executes the instructions
Store Output Operand (ST) - correct answer CU stores the result to the destination
(memory or register)
Cache Memory - correct answer Smaller, faster memory used by the CPU to reduce
the average time to access memory. The data from the most frequently used main
memory location is stored here.
