Processor fundamental

What is the purpose of the Control Unit in Von Neumann architecture?

• save data onto memory
• manage process of moving data in and out of memory
• controls the hardware components
• controls the software

What is the purpose of using the ALU?

• performing calculations on data
• controlling calculations on data
• controlling the speed of calculations
• save memory onto hard drive

What is the purpose of a 'Bus' in a computer system?

• Carry data to and from internal components
• execute user's instructions
• control flow of data
• connects the CPU to motherboard

What is the purpose of the program counter?

• Holds the current instruction to be executed, having been fetched from memory.  Contents are transferred to control unit for decoding.
• Stores the memory address of the next instruction. Incremented by one after an instruction is fetched. 

What is the purpose of registers in the CPU?

• To hold temporary data while a software program is running.
• To store files including graphics, sound and text files.

The Accumulator is a type of what?

• Register
• Buffer
• RAM
• Cache

What is the purpose of the Memory Data Register (MDR)?

• Holds the location of where the data is to be stored / read from
• Holds memory
• Holds instructions
• It does nothing

This component will fetch, decode and execute data and instructions.

• CPU
• RAM
• Hard drive
• ROM

This component will store the applications and data you are currently using.

• CPU
• RAM
• Hard drive
• ROM

The amount of times your CPU can complete the fetch-decode-execute cycle is known as

• The clock speed
• The number of cores
• The cache
• The RAM
