• Hyper Threading
• Multiplier
• Cores
• Bus Speed

Which of these busses allows the pc to transport data between the CPU and preiferals

• school bus

• data bus

• address bus

• control bus

Which of these busses allows the CPU to communicate with teh rest of the computer

• school bus

• data bus

• address bus

• control bus

Which of these busses sends data between the CPU and memory

• school bus

• data bus

• address bus

• control bus

What does the Control unit do

• The control unit controls and coordinates the activities of the CPU directing the flow of data between the CPU and other devices

• The control unit carries address information from the processor to main memory or peripherals.

• The control unit is a temporary holding ground for a instruction that has just been fetched from the memory

• The Control unit holds the address of the current instruction that is to be fetched from memory or the address in memory to which data is to be transferred.

What is clock speed measured in

• Htz

• seconds

• millimetres

• milometer

how many lines are typically in a bus

• 6

• 12

• 24

• 36

• 64

which of these is the Harvard architecture

• 2 memory cache locations, 2 buses, Memories can be different sizes,

  Program can write itself, Used for embedded systems

• 1 memory cache, 1 bus, Memory is read sequentially

  Memory could be overwritten by mistake,

  Used for more desktop PCs and laptops
