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

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:

RDIMM, Buffered memory

What is the most common memory module form factor type used in laptop computers?

SO-DIMM

(T or F) A single-sided memory module type can have memory chips placed on both sides of the module.

True

(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

(T or F)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

(t or F?) The speed of the system bus is measured in clock cycles, In computer architecture, the term "word" refers to a group of bits processed as a unit, A single clock cycle is an equivalent of a period of time between two adjacent signals sent by the system clock, The speed of the system bus in modern PCs is measured in MHz (i.e. millions of cycles per second)

True

A Single Data Rate Synchronous Dynamic Random Access Memory (SDR SDRAM) can read/write one word of data per clock cycle.

True

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 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 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)
