6. One difference between Dynamic RAM (DRAM) and Static RAM (SRAM) is: (a) DRAM loses information when power is switched off, but SRAM retains information when power is switched off. (b) DRAM tends to be more expensive than SRAM. (C) DRAM tends to be less dense than SRAM. (d) DRAM is faster than SRAM. () DRAM loses information unless it is periodically refreshed, SRAM will retain information indefinitely 7. Which of the following statements about the components of a computer are correct(if any): (a) The ALU is the part which executes the program. (b) The bus conveys information between the CPU and the microprocessor. (c) The clock signal is used by the CPU to time the phases of the instruction cycle. (d) A microprocessor is a CPU plus peripherals on a single chip. (e) Memory may be read-only (RAM) or read-write (ROM). 8. Which ONE of the following statements about interrupts is correct: (a) Interrupts occur when peripherals send bit-parallel signals to the CPU across the bus. (b) Interrupts occur when memory devices send bit-parallel signals to the CPU across the bus. (c) Interrupts occur when the CPU exerts a special signal line connected to a peripheral. (d) Interrupts occur when peripherals exert a special signal line connected to the memory. (e) Interrupts occur when peripherals exert a special signal line connected to the CPU. 9. Choose the best answer. The memory map side affects the nature of the microprocessor-based system bus, because: (a) the number of data lines must match the memory bit-width. (b) the number of address lines must allow the entire address range to be addressed. () if the number of data and address lines are the same, the lines can be multiplexed. (d) 9a and 9b are true but 9c is false. (e) 98, 9b and 9c are all true.
