Term

 

 

Data path size

Definition

 

The number of lines on a bus that can hold data, for example, 8, 16, 32, and 64 lines, which can accommodate 8, 16, 32, and 64 bits at a time.

 

Term

 

 

Complementary metal-oxide semiconductor

Definition

 

The technology used to manufacture microchips. These chips require less electricity, hold data longer after the  electricity is turned off, and produce less heat than earlier technologies.
