40 TOP COMPUTER HARDWARE and SOFTWARE Online Test – Questions and Answers 1. A computerized self-diagnostic for a ROM test uses: the check-sum method ROM comparisons a ROM listing a checkerboard test 2. Which of the following best describes static memory devices? semiconductor memory devices in which stored data is retained as long as power is applied memory devices that are magnetic in nature and do not require constant refreshing memory devices that are magnetic in nature and require constant refreshing semiconductor memory devices in which stored data will not be retained with the power applied unless constantly refreshed 3. Which of the following memories uses a MOSFET and a capacitor as its memory cell? SRAM DRAM DROM ROM 4. A nonvolatile type of memory that can be programmed and erased in sectors, rather than one byte at a time is: EEPROM EPROM flash memory MPROM 5. Select the best description of read-only memory (ROM) volatile, used to store information that changes during system operation nonvolatile, used to store information that changes during system operation volatile, used to store information that does not change during system operation nonvolatile, used to store information that does not change during system operation 6. The access time (tacc) of a memory IC is governed by the IC’s: volatility internal address buffer internal address decoder internal address decoder and volatility 7. What is the principal advantage of using address multiplexing with DRAM memory? no requirement for a chip-select input line, thereby reducing the pin count reduced requirement for constant refreshing of the memory contents reduced memory access time reduced pin count and decrease in package size 8.
