|
How many bits are in a byte? |
Eight |
|
|
What is the purpose of an expansion slot on a motherboard? |
It is used for an expansion card, which enables a device that is not on the Mobo to communicate with the CPU. |
|
|
Name two CPU manufacturers |
Intel and AMD |
|
|
What are two basic types of cables give inside a computer case and what are their basic functions? |
A data cable that passes data between devices and a power cable used to supply power to a device. |
|
|
List the types of ports often found coming directly off the mobo to be used by external devices. |
VGA port, USB port, serial port, network port, HDMI port, Display port, S/PDIF port, sound ports, and eSATA port |
|
|
What is the size of the data path on most system buses today? |
64 bits |
|
|
What is the measurement is frequency of a system bus and CPU? |
Hz, MHz, GHz |
|
|
Is frequency a measure of computer speed? |
The CPU clock cycles are measured in frequency (cycles per second) and the higher the frequency, the more clock cycles are available for processing. |
|
|
Name four types of slots that are likely to be found a mobo today |
PCI, AGP, PCIe X1, x4, x16 |
|
|
A power supply receives 120 __ of power from a wall outlet and converts it to 3.3, 5, 12 volts of __ power. |
AC, DC |
|
|
CMOS setup allows a technician to change configuration settings on a mobo stored in ___ |
CMOS RAM (or UEFI BIOS on modern computers). |
|
|
A Hertz is ____ cycles per second; a megahertz is ____ cycles per second, and a gigahertz is ____ cycles per second. |
One, one million, one billion |
|
|
An AGP (and PCIe in newer systems) is normally used for what expansion card? |
Video |
|
|
Name three purposes the Mobo ROM BIOS serves |
It manages simple devices (system BIOS), to start the computer (startup BIOS), and to change settings on the Mobo (CMOS setup) |
|
|
From where does CMOS ROM receive it's power? |
From the CMOS battery on the mobo |
|
|
If the CMOS battery inside your system died, when you first turn on your system, will you expect the system to boot up normally? |
No, the system wouldn't boot normally because the configuration information would not be available. This information includes the type of hard drive and floppy drive installed and the boot sequence. |
|
|
Why is it more accurate to describe the CPU and motherboard bus using the term frequency rather than speed? |
Because speed implies a continuous motion or flow of data, whereas frequency suggests a digital or binary flow of data. Frequency is more accurate because all processes inside the computer are referenced by machine cycles. |
|
|
What is the difference between true binary and coded binary? |
True binary is used inside the processor chip, coded binary is used by computers to store data and display results of Error-checking memory. |
