CPU Architecture Consolidation

What does CPU stand for?

• Computer Processing Unit

• Computing Process Unit

• Central Program Unit

• Central Processing Unit

Where are the instructions stored in Von Neumann Architecture?

• Main Memory

• CU

• ALU

• The Hard Drive

The ALU....

• does any maths or logic problems for the CPU

• stores data inside the CPU

• sends out control signals for the CPU

• holds specific data for the fetch-decode-execute cycle

The cache memory...

• does any maths or logic problems for the CPU

• stores frequently used instructions close to the CPU

• sends out control signals for the CPU

• holds specific data for the fetch-decode-execute cycle

Select the registers in the list below. [3]

• ALU

• MDR

• ACC

• PC

• CU

The CU...

• does any maths or logic problems for the CPU

• stores data inside the CPU

• sends out control signals for the CPU

• holds specific data for the fetch-decode-execute cycle

The computer would work without a CPU.

• True

• False

Which of the following is not part of the CPU itself?

• ALU

• CU

• Main Memory

• Registers

Select an example of Main Memory.

• RAM

• Hard Drive

• USB

• Clock

What does the clock do?

• Controls the speed at which the CPU executes a cycle.

• Tells the user the time.

• Allows the computer to remember the time when it's off.

• Times how long the CPU takes.
