PC Basics and Background - Review

1. A Personal Computer (PC) is normally a computer that:

   1. Can be moved from location to location.

   2. Contains a CPU, storage devices, memory, and a BUS.
   3. Can be a computer you can carry anywhere.
   4. All of the above.

2. Internally, a microprocessor (CPU) uses which of the following "numbering" system to perform its functions?
   1. Decimal
   2. Octal
   3. Binary
   4. Hexadecimal

3. A "RISC" based microprocessor
   1. processes 'complex' instructions about 80% of the time.
   2. is a 'Reduced Instruction Set Computer' architecture.
   3. processes MMS instructions slowly.
   4. all of the above

4. A PC's 'motherboard' will include all the following except
   1. the external cache.
   2. the expansion bus.
   3. BIOS.
   4. CD-ROM drive

5. PC's with multiple "CPUs" are well suited to
   1. Windows NT Server Operating System.
   2. MS-DOS operating system.
   3. Word Processor Applications.
   4. None of the above.

6. The most important part of a 'computing system' is the
   1. microprocessor
   2. operating system
   3. user
   4. memory

7. A "RISC" based computer is more efficient than a CISC based computer because
   1. it has a faster CPU and more memory.
   2. it uses a set of approximately 50 simple instructions that take fewer clock cycles to execute than CISC machine does.
   3. because Sun Microsystems produces them.
   4. they are not more efficient.

8. The 'chip', or ROM 'chip' that is used at boot time to perform the "POST" process, is called the
   1. Boot Sequence chip.
   2. BIOS chip
   3. Cache chip.
   4. Memory Controller chip.

9. A microprocessor that can move 3 or more instructions through the "fetch, decode, and execute" cycles, in sequence, where there are instructions in each of the different cycles, is a _________ system.
   1. Pipelining
   2. Superscalar
   3. network
   4. RISC

10. If you are purchasing a new microprocessor for home use, which of the following is possibly the "least" important factor?
    1. Memory Capacity.
    2. Number of CPUs.
    3. PCI Expansion slots.
    4. CPU Speed.

11. The instruction execution process in older PCs consisted of 3 cycles. They were the ______, ______, and ________ cycles.
    1. decode, get data, store results.
    2. fetch, decode, execute.
    3. get data, calculate, store results.
    4. none of the above.

12. The address of the first code to be executed after power on and the bootstrap code executes is the address of the
    1. ROM BIOS
    2. Autoexec.bat
    3. CMOS
    4. config.sys
