What do registers provide for the CPU? C. Registers enable the CPU to address RAM.
|
B. The CPU uses registers for temporary storage of internal commands and data. |
|
|
What function does the external data bus have in the PC? The external data bus determines the clock speed for the CPU. The CPU uses the external data bus to address RAM. The external data bus provides a channel for the flow of data and commands between the CPU and RAM. The CPU uses the external data bus to access registers.
|
C. The external data bus provides a channel for the flow of data and commands between the CPU and RAM. |

What is the function of the address bus in the PC? The address bus enables the CPU to communicate with the memory control- ler chip. The address bus enables the memory controller chip to communicate with the RAM. The address bus provides a channel for the flow of data and commands between the CPU and RAM. The address bus enables the CPU to access registers.
|
A. The address bus enables the CPU to communicate with the memory control- ler chip. |
|
|
Which of the following terms are measures of CPU speed? A. Megahertz and gigahertz D. Frontside bus, backside bus |
A. The terms megahertz (MHz) and gigahertz (GHz) describe how many mil- lion or billion (respectively) cycles per second a CPU can run. |
|
|
Which CPU feature enables the microprocessor to support running multiple operating systems at the same time? A. Clock multiplying B. Caching D. Virtualization support
|
D. Intel and AMD CPUs come with virtualization support, enabling more ef- ficient implementation of virtual machines. |
|
|
Into which socket could you place an Intel Core i5? A. Socket LGA 775 D. Socket AM2+
|
B. You’ll find Core i5 processors in several socket types, notably LGA 1155 and LGA 1154. |
|
|
Which feature enables a single-core CPU to function like two CPUs? A. Hyper-Threading C. Virtualization D. x64 |
A. Intel loves its Hyper-Threading, where a single-core CPU can function like a dual-core CPU as long as it has operating system support. |
|

What steps do you need to take to install an Athlon 64 X2 CPU into an LGA 775 motherboard? Lift the ZIF socket arm; place the CPU according to the orientation markings; snap on the heat-sink and fan assembly. Lift the ZIF socket arm; place the CPU according to the orientation markings; add a dash of heat dope; snap on the heat-sink and fan assembly. Lift the ZIF socket arm; place the CPU according to the orientation markings; snap on the heat-sink and fan assembly; plug in the fan. Take all of the steps you want to take because it’s not going to work. |
D. Intel and AMD processors are not compatible at all. |

A client calls to complain that his computer starts up, but crashes when Win- dows starts to load. After a brief set of questions, you find out that his nephew upgraded his RAM for him over the weekend and couldn’t get the computer to work right afterward. What could be the problem? Thermal compound degradation Disconnected CPU fan Bad CPU cache There’s nothing wrong. It usually takes a couple of days for RAM to acclimate to the new system. |
B. Most likely, the nephew disconnected the CPU fan to get at the RAM slots and simply forgot to plug it back in. |
|
|
Darren has installed a new CPU in a client’s computer, but nothing happens when he pushes the power button on the case. The LED on the motherboard is lit up, so he knows the system has power. What could the problem be? He forgot to disconnect the CPU fan. He forgot to apply thermal compound between the CPU and the heat-sink and fan assembly. He used an AMD CPU in an Intel motherboard. He used an Intel CPU in an AMD motherboard.
|
B. The best answer here is that he forgot the thermal compound, though you can also make an argument for a disconnected fan. |
