Chapter 5: Processor Fundamentals

Which of these are not the von Neumann model of a computer system?

• There is a processor - central processing unit (CPU)

• The processor has direct access to memory

• The stored program consists of collective instructions

• The stored program consists of individual instructions

The two active components of the CPU are the Arithmetic Logic Unit (ALU) and the __________

• Register

• Program Counter

• Control Unit

• Memory

The two units that are used to synchronise processes in the control unit are internal clock and ________

• the ALU

• the control unit

• system bus

• system clock

Which one of these are not special-purpose register

• current instruction register

• index register

• logic register

• program counter

Which of these are in the system bus?

• The address bus

• The register bus

• The logic bus

• The mini bus

Which of these are not factors contributing to system performance?

• The word length

• Processor clock speed

• The bus width

• The register

The sole function of the address bus is to carry an address. Is this true or false?

• True

• False

• Maybe

• I dont know

The universal serial bus (USB) is used to

• provide high resolution screen display

• connect a peripheral

• allow the transmission of high quality video

• control the system clock

When a program is running, the program counter will hold the _________ of the next instruction

• clock cycle

• system clock

• address

• data

One of these is not reasons for an interrupt to be generated:

• the program counter is incremented by 1

• an error in a program

• hardware fault

• a timer signal
