1.1.1 The CPU

What does CPU stand for?

• Computer Processing Unit
• Central Processing Unit
• Central Process Unit
• Centralised Processing Unit

What does the CPU process?

• Data
• Instructions
• Data and instructions
• Information

What does clock speed mean?

• How fast it stores instructions
• How fast it stores data
• How fast it travels when thrown
• How many F-D-E cycles it can do per second

If a CPU has 4 cores what does it mean?

• The CPU can carry out more instructions at once
• The CPU is able to store more instructions
• The CPU will have a large cache
• The CPU will have a faster clock speed

What is the function of a CPU's cache memory?

• To store cores
• Fetches instructions from RAM and stores them
• Stores previously calculated instructions for faster access
• Copies data from RAM when it gets full

What is the function of the control unit?

• Has overall control of the CPU.  It's in charge of the F-D-E cycle
• It does all of the calculations
• It is very fast memory in the CPU
• The CPU runs programs stored in memory

What does ALU stand for?

• Arguable Logic Unit
• Arithmetic Larger Unit
• Arithmetic Logic Unit 
• Arithmetic Logic Utility

What is the function of the ALU?

• Performs all the logic 
• Stores previously executed instructions
• Has overall control of the CPU
• Performs all the calculations

Which best describes the CPU's fetch cycle?

• The CPU fetches information from RAM
• The CPU fetches information from ROM
• The CPU fetches data from RAM
• The CPU fetches information from the HDD

Which best describes the CPU's decode job?

• Takes binary, turns it into information
• Takes information and performs calculations
• Data is sent to RAM where it decodes binary
• Takes binary, calculates and makes comparisons, turns it into an instruction
