IT Vocab PC 5

Question 1

A form of embedded flash memory widely seen in mobile devices

Answer 1

eMMC

Question 2

RAM Stick with RAM chips soldered to both sides of the stick. May only be used with motherboards designed to accept.

Answer 2

double-sided RAM

Question 3

RAM without a buffer chip; in other words, normal, consumer-grade RAM

Answer 3

unbuffered RAM

Question 4

Chip that handles memory requests from the CPU. Although once a special chip, it has been integrated into the chipset or CPU

Answer 4

memory controller chip (MCC)

Question 5

Method of error detection where a small group of bits being transferred is compared to a single parity bit set to make the total bits odd or even. Receiving device reads the bit and determines if the data is valid based on the oddness or evenness of the bit

Answer 5

parity

Question 6

Memory that can be accessed at random–that is, memory that you can write to or read from without touching the preceding address

Answer 6

RAM

Question 7

Type of SDRAM that sends 4 bits of data in every clock cycle

Answer 7

DDR2

Question 8

Special software, embedded on hard drives, that constantly scans the drives for bad sectors

Answer 8

error correction code (ECC)

Question 9

Speed at which a CPU executes instructions, measured in MHz or GHz

Answer 9

Clock cycle

Question 10

Circuitry used on video cards that support analog monitors to convert the digital video data to analog

Answer 10

RAMDAC

Question 11

Feature similar to dual-channel RAM, but requiring four sticks instead of two

Answer 11

quad-channel architecture

Question 12

Memory that must have constant electricity to retain data

Answer 12

volatile

Question 13

Unit of 8 bits; fundamental data unit of personal computers. Storing the equivalent of one character

Answer 13

bytes

Question 14

The process of keeping files on mobile devices up to date with the versions on desktops computers or over the internet

Answer 14

Sync

Question 15

Using two sticks of RAM to increase throughput

Answer 15

dual-channel architecture

Question 16

Expansion card that works with the CPU to produce the images displayed on your display

Answer 16

video card

Question 17

Generic name for a single physical SIMM or DIMM

Answer 17

stick

Question 18

Ultra-low-voltage version of DDR3

Answer 18

DDR3U

Question 19

Type of SDRAM that transfers data twice the rate of DDR2 SDRAM

Answer 19

DDR3

Question 20

Memory used to store data in most personal computers; stores each bit in a “cell” composed of a transistor and a capacitor

Answer 20

dynamic random access memory

Question 21

Form of DDR, DDR2, and DDR3 memory access used by many motherboards that requires low identical sticks of memory

Answer 21

dual-channel memory

Question 22

RAM that uses special chips to detect and fix memory errors. Commonly used in high-end servers where data integrity is crucial

Answer 22

ECC RAM

Question 23

Set of wires leading from the CPU to the memory controller chip that enables the CPU to address RAM

Answer 23

address bus

Question 24

A chipset feature similar to dual-channel RAM, but requiring three matched sticks instead of two

Answer 24

triple-channel

Question 25

Type of SDRAM that offers higher density and lower voltages that DDR3 and can handle faster data transfer rates

Answer 25

DDR4

Question 26

low-voltage version of RAM. Provides cost savings in large deployments, such as a data center

Answer 26

DDR3L
