What function does the external data bus have in the PC?
a. The external data bus determines the clock speed for the CPU.
b. The CPU uses the external data bus to address RAM
c. The external data bus provides a channel for the flow of data and commands between the
CPU and RAM
d. The CPU uses the external data bus to access registers.
What is the function of the address bus in the PC?
a. The address bus enables the CPU to communicate with the memory controller chip.
b. The address bus enables the memory controller chip to communicate with the RAM.

Steve adds a second 1-GB 240-pin DIMM to his PC, which should bring to total RAM in the system up to
2GB. The PC has an Intel Core 2 Duo 3GHz processor and tree 240-pin DIMM slots on the motherboard.
When he turns on the PC, however, only 1 GB of RAM shows up during the RAM count. Which of the
following is most likely to be the problem?
a.
b.
c.
d.
Steve failed to seat the RAM properly,
Steve put DDR SDRAM in a DDR2 slot.
The CPU cannot handle 2 GB of RAM
The motherboard can use only one RAM slot at a time.
Steve wants to add 512 MB of PC100 SDRAM to an aging but still useful desktop. The system has a 100MHz motherboard and currently has 256 MB on non-ECC SDRAM in the system. What else does he need
to know before installing?
a.
b.
c.
d.
What speed of RAM he needs.
What type of RAM he needs.
How many pins the RAM has
If the system can handle that much RAM
What is the primary reason that DDR2 RAM is faster than DDR RAM?
a.
b.
c.
d.
The core speed of the DDR2 RAM chips is faster
The input/output speed of the DDR2 RAM is faster.
DDR RAM is single-channel and DDR2 RAM is dual-channel
DDR RAM uses 184-pin DIMMs and DDR2 uses 240-pin DIMMs
What is the term for the delay in the RAM’s response to a request from the MCC?
a.
b.
c.
d.
Variance
MCC gap
Latency
Fetch interval
Joe has a motherboard with four RAM slots that doesn’t seem to work. He has two RDRAM RIMMs
installed, for a total of 1 GB of memory, but the system won’t boot. What is likely the problem?
a.
b.
c.
d.
The motherboard requires SDRAM, not RDRAM
The motherboard requires DDR SDRAM, not RDRAM
The motherboard requires all four slots filled with RDRAM
The motherboard requires the two empty slots to be filled with C-RIMMs for termination.
Bob has a AMD-based motherboard with two sticks of DDR2 RAM installed in two of the three RMA
slots, for a total of 2 GB of system memory. When he runs CPU-Z to test the system, he notices that the
software claims he’s running single-channel memory. What could be the problem?
A.
B.
C.
D.
His motherboard only supports single-channel memory
His motherboard only supports dual-channel memory with DDR RAM, not DDR2
He needs to install a third RAM stick to enable dual-channel memory.
He needs to move one of the installed sticks to a different slot to activate dual-channel
memory.
