Review Questions

1. 

Which processor was released in the first IBM PC?

intel 8088

2. 

How did the 8086 differ from the 8088?

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

3. 

What does CPU speed refer to?

the number of operations that are processed in one second

4. 

How does SDRAM differ from EDO RAM?

sdram can transfer data at 100mhz.

5. 

How does real mode differ from protected mode?

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

6. 

What does clock cycles refer to?

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. 

What is Virtual Real Mode?

virtual real mode is software built into windows95/98/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. 

What does PROM stand for, and what is it?

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. 

What does the term clock doubling refer to?

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

10. 

How many transistors make up the original Pentium processor?

3.1 million

11. 

How does asymmetrical multiprocessing differ from symmetrical?

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. 

What is a math coprocessor?

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. 

What is the recommended amount of RAM for Windows Server 2003?

microsoft recommends 512mb of physical ram for windows server 2003.

14. 

What is the primary difference between RAM and ROM?

ram is dynamic, meaning that its contents constantly change. permanent information, such as the bios, is stored in rom.

15. 

What performance gains does PCI have over the EISA bus architecture?

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.
