ECC type RAM:
Can detect and correct errors
Certain types of RAM take advantage of an additional bit in order to detect whether a data error has occurred. An extra bit is used to store information about the number of bits set to the value of one in a given string of data (typically one byte) and by examining that information at different stages of processing it is possible to detect whether the data has been corrupted or not. What is the name of that extra bit?
Parity bit
Compared to a non-ECC type of memory, the ECC RAM is a less expensive option and will always perform faster.
False
The color-coded memory slots on the motherboard indicate that the system is capable of taking advantage of the multi-channel memory architecture.
True
Which of the following characteristics apply to the type of RAM most commonly used as the main system memory in desktop PCs?
Non-ECC memory
Unbuffered memory
Dynamic RAM
Taking advantage of the performance benefits offered by the multi-channel memory architecture requires:
Memory modules of matching types
Memory modules of matching speeds
Memory modules of the same capacity
Installing modules in appropriate memory slots (slots of matching color) on the motherboard
A type of typically more expensive memory modules equipped with additional circuitry designed to ensure better system stability and accuracy of data processing is known as:
Buffered memory
RDIMM
A single-sided memory module type can have memory chips placed on both sides of the module.
True
Which of the following RAM types would be the most suitable choices for a high-end server?
Buffered memory
RDIMM
ECC memory
A special-purpose memory type used by graphics controllers is known as:
VRAM
Which of the memory types listed below allows for permanent storage of data?
DVD-RAM
A type of Printed Circuit Board (PCB) that can be installed in a motherboard slot in order to extend the system functionality is commonly referred to as an expansion card.
True
What type of safety measures should accompany the installation of an adapter card?
ESD protection
If a system fails to autoconfigure the newly added adapter card through PnP, finishing the configuration process requires manual installation of device drivers.
True
A type of daughterboard equipped with expansion slots providing the capability for attaching further expansion cards that are placed parallel with the mainboard in order to save space inside the system case is known as:
Riser card
Which of the following answers list(s) example(s) of storage media type(s) that can be read, but not written to?
CD-ROM
DVD-ROM
Which of the terms listed below refers to computer data storage systems, data storage devices, and data storage media that can be written to once, but read from multiple times?
WORM
Which of the following is an example of Write Once, Read Many (WORM) storage media type?
BD-R
