RAM Quiz Flashcards
Which of the following memory module form factors are used in laptop computers?
SODIMM
MicroDIMM
TRUE/FALSE
RAM is an example of volatile storage media. It requires a continuous flow of electricity to preserve its contents; therefore all data stored in RAM lasts only while the power is on.
True
Which type of memory allows for permanent data storage?
DVD RAM
Which of the following is a special purpose memory type used by graphics controllers?
VRAM
video RAM
True/False
The term SDRAM (synchronous dynamic) encompasses a brad range of DRAM modules that rely on a signal sent by the system clock in order to synchronize the memory operation with other PC components.
TRUE
What are some characteristics of DDR2 SDRAM?
1 notch on the module contact surface
4 words of data per clock cycle
240 contact pins
Which of the following is the industry name used for DDR2-1066 modules?
PC2 - 8…
PC2-8500
What is the peak transfer rate of a DDR2-533 module?
4266 MB/S
DDR2 SDRAM SODIMM memory modules contain how many pins?
200 contact pins
What are some characteristics of DDR3 SDRAM?
240 contact pins
8words per clock cycle
1 notch on module contact surface
What is the industry name of DDR3-1333 modules?
PC3 - 10…
PC3-10600
What is the peak transfer rate of a DDR3-1600 module?
12800 MB/s
How many pins are used in SODIMM DDR3 SDRAM modules?
204
Which of the following are characteristics of DDR4 SDRAM?
288 contact pins
8 words per clock cycle
1 notch on contact surface
DDR4-2666 is also known as:
PC4-.21..
PC4-21300
What is the peak transfer rate of a DDR4-3200 module?
25600 MB/s
How many pins are used in SODIMM DDR4 SDRAM modules?
260
TRUE/False
A motherboard with color coded memory slots provides support for multi channel memory architecture.
True
What is required to take advantage of the performance benefits offered by the multi channel memory architecture?
Installing memory modules of matching types/speed/capacity
installing modules in appropriate slots
What can ECC RAM do?
Can detect and correct errors.
Certain types of RAM use an additional bit in order to detect whether a data error has occured. This extra bit is used to store information about how many bits are set to a value of 1 in a given string.
Examining this extra but allows to detect whether data is corrupted or not. What is the name of this extra bit?
Parity bit
Which of the following are characteristics of the type of RAM most commonly used as the main system memory in desktop PCs?
Non ECC (error correcting) memory
Dynamic RAM
