           State TWO features of the original design, which have
           contributed to the success of the product.
                                                               [10]

     (b)   Explain how compliance with the specifications from
           Intel and Microsoft maintain standards for the PC
           architecture.
                                                                  [5]
     (c)   Discuss the future for non-Windows based operating
           systems and software (e.g. Linux )
                                                                  [5]


2.
     (a)    List TEN important functional blocks in the current PC
           architecture.
           Discuss why most of these functions are now
           implemented as part of the chipset/ PC motherboard.
           Comment on any limitations this imposes on PC
           System integrators.

     (b)   Outline the features of the Pentium, Pentium II, Pentium
           III and Pentium 4 which have made these chips the de
           facto standards for modern PCs.
                                                                  [5]
     (c)   Compatibility has always been an important feature of
           the x86 family.
           Explain clearly what compatibility means.
           Will future products maintain this compatibility ?
                                                                  [5]

           typical access times.
                                                                  [5]
     (b)   Discuss why memory is such an important element in
           determining the performance of a PC.
                                                                  [5]

5.
      (a)   Describe how peripherals are accessed in the PC
            Architecture.
            Explain how interrupts allow the various peripherals
            (and other devices) to share the CPU and enhance the
            response time.

            Use the following peripheral as an example:
             Serial Channel COM1: IO Address Range = 03f8-03ff
               Interrupt = 04
                                                                  [5]
     (b)    The printer on a PC has traditionally used a parallel
            port.
            Explain why this was important for a product aimed at
            non-specialised users (the alternative was the RS232
            serial link).
                                                                  [5]
     (c)    Describe the technology of the keyboard on a PC.
            List the events which follow a key press in a DOS or
            Windows application.
                                                                  [5]

     (d)    Discuss the move in PCs from traditional peripherals
            e.g. mouse, keyboard, PC speaker etc. to USB based
            peripherals.
                                                                 [5]

6.
     (a)    Explain why the ISA-bus dominated the PC product
            until the 90s.
            IBM developed an alternative called MCA (Micro
            Channel Architecture).
            Why was the MCA-bus unsuccessful ?
                                                                  [5]
      (b)   Modern PCs use the PCI-bus for adapter cards.
            List FIVE features of the PCI-bus which makes it so
            popular.
                                                                  [5]
      (c)   Modern PCs use the AGP as well as the PCI-bus.
            Explain why the PCI-bus isn’t able to cope with modern
            video requirements.
                                                                 [5]
      (d)    Windows 95/ 98/ ME are described as Plug-and-Play
            compatible.
            What does the term Plug-and-Play mean and why is it
            desirable for modern cards e.g. video, disk, sound,
            modem.
            Outline the technology behind Plug-and-Play.
                                                                 [5]

      (a)   List the major disk and backup technologies used in
            PCs.
            The list should include information about speed,
            performance and size.
                                                                  [5]
      (b)   Draw a block diagram of an IDE disk subsystem.
            Review the development of the IDE standard.
            How does a CD-ROM drive attach to an IDE system ?
                                                                [10]
      (c)   Draw a block diagram of an SCSI disk subsystem.
            Explain why SCSI drives are more likely to be used for
            a server rather than a desktop PC.
                                                                 [5]

                                                               [5]
     (c)   The PC link to a modern modem needs to have a faster
           bit rate than the data link to the telephone line.
           Explain why this is necessary.
                                                               [5]
     (d)   Sketch the architecture of a PC incorporating a Network
           Interface Card.
