Appendix A: Answers to Review Questions

Chapter 1

  1. Intel 8088

  2. The 8-bit 8088 provided a more cost-effective product for IBM to release, replacing the true 16-bit 8086 processor.

  3. The number of operations that are processed in one second

  4. SDRAM can transfer data at 100MHz.

  5. Real mode accesses memory in a linear format, whereas protected mode can allocate memory to a specific task.

  6. Clock cycles represent the internal speed of a computer or processor expressed in megahertz. The faster the clock speed, the faster the computer performs a specific operation.

  7. Virtual Real Mode is software built into Windows 95/98/NT that enables DOS programs to run. Virtual Real Mode creates a software-based memory space called conventional memory that is needed for DOS programs to run.

  8. PROM stands for Programmable Read-Only Memory and is a special type of chip that is manufactured without any configuration. Manufacturers can then burn in, or program, the chip to contain whatever configuration is needed.

  9. Clock doubling refers to the mechanism that enables the internal system clock to run at twice the normal rate of speed.

  10. 3.1 million

  11. Asymmetrical multiprocessing uses a separate processor to run the operating system and a second processor to run the applications. Symmetrical multiprocessing shares the tasks equally among the processors.

  12. A math coprocessor, or Floating Point Unit (FPU), is a secondary processor that speeds operations by taking over some of the main processor's work. It typically performs mathematical calculations, freeing the processor to tend to other tasks.

  13. Microsoft recommends 512MB of physical RAM for Windows Server 2003.

  14. RAM is dynamic, meaning that its contents constantly change. Permanent information, such as the BIOS, is stored in ROM.

  15. PCI has a wider data path of 32 bits and runs at 33MHz. Much faster than any other bus architecture before it, PCI also improves CPU performance by relieving the CPU of many tasks that are handled by the PCI-Host bridge.
