DVD-RAM

SDRAM's backward compatibility feature provides a convenient way to build PCs utilizing different types of SDRAM modules.

False

Which of the following are characteristic features of Static Random-Access Memory (SRAM)? (Select all that apply)

Faster than Dynamic Random-Access Memory (DRAM), More expensive in comparison to Dynamic Random-Access Memory (DRAM), Volatile storage media type, & Utilized for CPU cache memory chips

Which of the following memory module form factors are used in laptop computers? (Select 2 answers)

SODIMM, & MicroDIMM

Placing a notch on a RAM module contact surface allows the module to be properly aligned with a memory bank on the motherboard and prevents the installation of incompatible memory types.

True

Random Access Memory (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

The term "Synchronous Dynamic Random-Access Memory (SDRAM)" encompasses a broad range of DRAM modules that rely on a signal sent by the system clock in order to synchronize the memory operation with other internal PC components.

True

Which of the following are characteristics of Dynamic Random-Access Memory (DRAM)? (Select all that apply)

Volatile storage media type, Slower than Static Random-Access Memory (SRAM), Widely used as system's primary storage media (regular RAM modules installed in memory slots on the motherboard), & Less expensive in comparison to Static Random-Access Memory (SRAM)
