The term gigahertz, or GHz, refers to the operating speed of a central processing unit; hertz defines the clock rate, or cycles per second, of the CPU. 1 GHz is equivalent to one billion hertz. Businesses can increase the frequency of a processor to improve the speed of a computer through a process known as overclocking..
Purpose. Surfactant reduces the surface tension of fluid in the lungs and helps make the small air sacs in the lungs (alveoli) more stable. This keeps them from collapsing when an individual exhales.or example, if a drop of detergent is added to a drop of water, the detergent reduces the surface tension and the drop of water flattens out. In the lungs, surfactant reduces the surface tension and helps to maximize the surface area available for gas exchange.
Surfactant Definition: Surfactant is the word that combines the terms surface active agent.Chemical species that acts as wetting agents to lower the surface tension of a liquid and allow for increased spreadability.This can be at a liquid-liquid interface or a liquid-gas interface. Also Known As: tenside. Examples: coating on the surface of the alveoli in the lungs.urfactant Definition: Surfactant is the word that combines the terms surface active agent.
