You have a customer who wants you to add some memory to a laptop his son uses. It currently has one 144-pin SODIMM module with a speed of PC-100. The memory module you brought with you for the upgrade is identical except that its speed is PC-133. What will happen if you try to upgrade the memory of this computer with the PC-133 SODIMM module? A. The memory modules must be identical. If you try the upgrade, the computer will fail to boot. B. The memory modules must be identical. If you try the upgrade, the computer will boot, but only recognize the slowest stick of memory. C. The memory modules do not have to have identical speeds. The computer will recognize both modules but only run at the speed of the slowest module. D. The memory modules do not have to have identical speeds. The computer will recognize both modules and will run at the speed of the fastest module. Solution C. PC-100 is the clock speed of the memory and means the memory clock frequency is 100 MHz. .

has one 144-pin SODIMM module with a speed of PC-100. The memory module you brought
with you for the upgrade is identical except that its speed is PC-133. What will happen if you try
to upgrade the memory of this computer with the PC-133 SODIMM module?
A. The memory modules must be identical. If you try the upgrade, the computer will fail to boot.
B. The memory modules must be identical. If you try the upgrade, the computer will boot, but
only recognize the slowest stick of memory.
C. The memory modules do not have to have identical speeds. The computer will recognize both
modules but only run at the speed of the slowest module.
D. The memory modules do not have to have identical speeds. The computer will recognize both
modules and will run at the speed of the fastest module.
Solution
C. PC-100 is the clock speed of the memory and means the memory clock frequency is 100
MHz.
