What does CPU stand for?

• Computer Processing Unit

• Central Processing Unit

• Central Permutation Unit

• Conflagrational Pessimism Ubiquity

Which of the following is a method for measuring the performance of a CPU?

• Amount of cache

• Clock speed

• Number of cores

• All of the above

In the context of the Von Neumann architecture, what does PC stand for?

• Personal Computer

• Program Calculator

• Program Counter

• Position Counter

What is a register?

• That thing your teacher always forgets to do at the start of the lesson

• A very small temporary memory store located inside the CPU

• A reasonably large temporary memory store located on the CPU in order to speed up processing

• A location in memory which stores the program being run

What is the purpose of the data bus?

• To transport data from the CPU to the memory store, or from the memory store to the CPU

• To store the address to be accessed by the CPU

• To perform calculations required by the program

• To transport data from the memory store to the CPU but NOT back the other way

The memory store contains the following data:

000 - LDA 005

001 - ADD 006

002 - STA 004

003 - HALT

004 - 567

005 - 4

006 - 68

What is the value stored in the PC after a single cycle?

• 1

• 0

• LDA 005

• 005

Select the THREE stages of a Von Neumann CPU cycle

• Process

• Decode

• Decrypt

• Execute

Jodi wants to run multiple applications at the same time (for example, a video editor, post processing tools and a compression program. Which CPU will be best?

• A single core CPU with 8MB cache running at 5GHz

• A quad core CPU with no cache running at 3.5GHz

• A quad core CPU with 4MB cache, running at 3.5GHz

• A dual core CPU with 16MB cache, running at 4.5GH

The memory store contains the following data:

000 - LDA 005

001 - ADD 006

002 - STA 004

003 - HALT

004 - 567

005 - 4

006 - 68

What is contained in the current instruction register after the SECOND cycle?

• LDA 005

• ADD 006

• 0

• 1

A small but very fast temporary storage area located on the CPU is called the...

• cache

• core

• bus

• accumulator
