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.
A substance capable of reducing the surface tension of a liquid in which it is dissolved. Classified under: Nouns denoting substances. Synonyms: surface-active agent; surfactant; wetter; wetting agent. Hypernyms (surfactant is a kind of...): chemical agent (an agent that produces chemical reactions) Hyponyms (each of the following is a kind of surfactant): emulsifier (a surface-active agent that promotes the formation of an emulsion) detergent (a surface-active chemical widely used in industry and laundering)
