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

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.
