ECC type RAM:

Can detect and correct errors

Compared to non-ECC memory, ECC RAM is a less expensive option and will always perform faster.

False

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

False

Small Outline Dual In-Line Memory Module (SO-DIMM) is a more compact type of computer memory designed for desktop PCs.

False

The color-coded memory slots on the motherboard indicate that a given motherboard provides support for the multi-channel memory architecture.

False

Which of the answers listed below refer(s) to the characteristic feature(s) 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

Taking advantage of the performance benefits offered by the multi-channel memory architecture requires: (Select all that apply)

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

Which of the following characteristics apply to the type of RAM most commonly used as the main system memory in desktop PCs? (Select 2 answers)

Non ECC memory Dynamic RAM

Which of the answers listed below refers to a valid SDRAM module combination that can be installed on a single PC motherboard?

None of the above

Certain types of RAM take advantage of an additional bit in order to detect whether a data error has occurred. This extra bit is used to store information about the count of bits set to the value of 1 in a given string of data (typically one byte). Examining the value of the additional bit at different stages of processing allows to detect whether the data has been corrupted or not. What is the name of that extra bit?

Parity bit

A type of file on the storage drive that an OS can use to hold parts of programs and data files that cannot be stored in RAM due to the insufficient memory space is called: (Select 3 answers)

Swap file Paging file Virtual ram

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

The placement of a notch on the RAM module contact surface allows for proper alignment of the module with the memory bank on the motherboard and prevents the installation of incompatible memory types.

True

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

Which of the following can be used as an extension of RAM? (Select all that apply)

Virtual memory Swap/paging file Swap partition

Which of the following answers describes(s) the 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)
