What is a core?

• the centre of a CPU

• a basic computational unit of a CPU

• the brain of a CPU

• the basic conversational unit of the CPU

What does a single core carry out?

• FDE Bicycle

• FED Cycle

• FDE Cycle

• Fetch Decode Extreme Cycle

What is clock speed?

• The number of FED cycles per second

• The number of instructions that can be processed per hour by a CPU

• The number of FDE cycles per second

• The number of instructions that can be processed per second by a CPU

What is the purpose of the CPU?

• to fetch, decode and execute instructions

  stored in RAM. RAM is NOT part of the CPU

  
  

• to control the flow of data around the CPU during the FDE cycle

• to carry out calculations, binary shifts and logical operations

• to store frequently used instructions closer to the CPU

What is the purpose of the Control Unit?

• to fetch, decode and execute instructions

  stored in RAM. RAM is NOT part of the CPU

  
  

• to control the flow of data around the CPU during the FDE cycle

• to carry out calculations, binary shifts and logical operations

• to store frequently used instructions closer to the CPU

What is the purpose of the Arithmetic Logic Unit?

• to fetch, decode and execute instructions

  stored in RAM. RAM is NOT part of the CPU

  
  

• to control the flow of data around the CPU during the FDE cycle

• to carry out calculations, binary shifts and logical operations

• to store frequently used instructions closer to the CPU

What is the purpose of Cache memory?

• to fetch, decode and execute instructions

  stored in RAM. RAM is NOT part of the CPU

  
  

• to control the flow of data around the CPU during the FDE cycle

• to carry out calculations, binary shifts and logical operations

• to store frequently used instructions and data closer to the CPU

What is the purpose of a register?

• to store an item of data or a memory address during the FDE cycle.

  
  

• to control the flow of data around the CPU during the FDE cycle

• to carry out calculations, binary shifts and logical operations

• to store frequently used instructions and data closer to the CPU

What is stored in RAM?

• data

• instructions

• instructions in one area of RAM &

  data in a different area of RAM

• instructions and data all mixed together
