RAM Quiz Flashcards
(T or F) Random Access Memory (RAM) falls into the category of the so-called volatile storage media. It requires a continuous flow of electricity to preserve its contents thus all the data stored in RAM lasts only while the power is on.
True
What are 4 characteristic feature(s) of Static Random Access Memory (SRAM)?
Faster than DRAM, More expensive than DRAM, Volatile storage, and Utilized for CPU cache memory chips
What 4 characteristics describes Dynamic Random Access Memory (DRAM)?
Slower than SRAM, Less expense than SRAM, Volatile storage media type, and Widely used as primary storage media.
(T or F) The term “Synchronous Dynamic Random Access Memory (SDRAM)” refers to a broad category of DRAM modules that rely on the signal sent by the system clock in order to coordinate their functioning with other internal PC components.
True
(T or F) A Single Data Rate Synchronous Dynamic Random Access Memory (SDR SDRAM) can read/write one word of data per clock cycle.
True
What is the number of contact pins used in SDR SDRAM modules?
168
What are the characteristic features of the Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM)? (3 answers)
184 contact pins, Reads/Writes 2 words of data per clock cycle, & 1 notch on module.
What is the the industry name used for DDR-333 modules?
PC-2700
What is the peak transfer rate of a DDR-266 module?

(T or F) Compared to a non-ECC type of memory, the ECC RAM is a less expensive option and will always perform faster.
False
(T or F) The color-coded memory slots on the motherboard indicate that the system is capable of taking advantage of the multi-channel memory architecture.
True
What characteristics apply to the type of RAM most commonly used as the main system memory in desktop PCs? (3 answers)
