D316 IT Foundations (Weak Points) Practice
questions and Verified Answers
DDR5
Memory Type that Offers two 32-bit channels per Module.
quadruple-channel
System-memory controller configuration that provides four data pathways between the
memory modules and a compatible CPU. Requires the right amount of modules to be installed
to take advantage of the technology.
Flex Mode
Memory size mismatch. if using a 2 GB and a 6 GB, only the 2 GB will be used in dual-channel
mode, the 6 GB will be used in single channel mode.
Pagefile
Extended memory space used in windows.
Virtual Memory
Total amouny of addressable memory + swap space
FD624
UHS-III, Offers the highest recording speeds (624 Mbps)
SLC SSD
Single-Level Cell. Type of SSD. More reliable and expensive type.
MLC SSD
Multi Level. It's not as reliable and less expensive. Susceptible to a type of degragation over the
course of many write operations.
, TLC SSD
Triple-Level. Less reliable and less expensive. It's firmware and operating systems use a wear-
leveling routines that evenly distribute writing on all blocks of an SSD to optimize the life of the
device.
B Key SSD Slot
6 Pins wide usually after notch on right
M Key SSD Slot
5 pins wide usually before notch on left
PCI Cards Voltage
3.3V & 5V
PCI Cards Key
Prevents a user from inserting incompatible cards into a motherboard slot.
VDC rails
Wire providing current at a particular voltage. The most important is 12V.
Stereolithography 3-D Printer
Uses liquid plastic resin to create objects.
Feed Assembly
• Pull paper through the printer
• Relatively small paper path
Thermal Printers
apply heat to special thermal paper, turning select areas black to produce text and basic
graphics.
