access time
the time it takes a storage device to locate its stored data
Cache memory
Small blocks of memory, located directly on and next to the CPU, that act as holding places for recently or frequently used instructions or data that the CPU accesses the most.
Cores-
A complete processing section from a CPU, embedded into one physical chip
CPU usage graph
the percentage of time a central processing unit (CPU) is working
Data transfer rate
the maximum speed at which data can be transmitted between two nodes on a network
External SATA-
The most common form of memory found in personal computers. Increases about 60% every year
Express Cards-
Allow your computer to add extra capabilities such as; a card that allows you to read flash memory
Front side bus-
connects the processor (CPU) in your computer to the system memory
GDDR5 (Graphic Double Data Rate)
Graphic Double Data Rate memory refers to memory specifically designed for use on graphics cards
GPU Graphics processing unit
A specialized logic chip that is detected quickly displaying and calculating visual data such as shadows, textures, and luminosity
hard drive
has the largest storage capacity of any storage device
HDMI (High definition multimedia interface
a compact audio- video interface standard that carries both high- definition video and uncompressed digital audio
memory modules
a small circuit board that holds a series of ram chips
moore's law
a prediction named after Gordon Moore, the cofounder of Intel; states that the numbers of transistors on a CPU chip will double every two years
RAID 1
a storage technology that combines multiple disk drive components into a logical unit
RAM (random access memory)
the computers temporary storage space or short term memory. it is located in a set of chips in the system unit's motherboard, and its capacity is measured in megabytes or gigabytes
3d sound card
an expansion card that enables a computer to produce sounds that are omnidirectional
SSD (solid state drive)
a drive that uses the same kind of memory that flash drives use, but can reach data in only a tenth of the time a flash drive requires. Fastest nonvolatile storage system.
surround sound
a type of audio processing that makes the listener experience sounds as if it were coming from all areas

False
T or F GDDR5 memory is often used in ESATA drives
False
