CPU moos ceev, lossis moos tus nqi, yog ntsuas hauv Hertz - feem ntau hauv gigahertz , los yog GHz . CPU lub moos ceev tus nqi yog a ntsuas ntawm pes tsawg lub voj voog ib CPU tuaj yeem ua tau ib ob. Piv txwv li, CPU nrog lub moos tus nqi ntawm 1.8 GHz tuaj yeem ua tau 1,800,000,000 moos cycles ib ob.

Ua kom pom qhov no, GHz txhais li cas rau cov khoos phis tawj?

Lub moos ceev yog tus nqi uas tus processor ua haujlwm thiab ntsuas hauv Gigahertz ( GHz ). Ib zaug, tus lej siab dua txhais tau tias lub processor ceev dua, tab sis kev nce qib hauv cov thev naus laus zis tau ua rau cov processor nti ua haujlwm tau zoo dua li tam sim no lawv ua ntau nrog tsawg.

Tom qab ntawd, lo lus nug yog, dab tsi yog 1.6 GHz processor? A 1.6 Ghz processor txhais tau tias tias muaj 1.6 billion "zuam" ntawm lub moos ib ob, thiab txhua cov lus qhia uas tus CPU nkag siab yuav siv qee tus zuam kom tiav.

Hauv qhov no, qhov ntsuas gigahertz yog dab tsi?

Luv rau gigahertz , GHz yog ib tug unit ntsuas rau AC (alternating tam sim no) los yog EM (electromagnetic) yoj zaus sib npaug rau 1,000, 000, 000 (ib billion) Hz (hertz). 2. Thaum xa mus rau lub computer processor lossis CPU, GHz yog lub moos zaus, tseem hu ua tus nqi moos lossis moos ceev, sawv cev rau lub voj voog ntawm lub sijhawm.

Lub computer ceev ntsuas nyob rau hauv dab tsi?

Unit ntawm ntsuas hu ua hertz (Hz), uas yog technically ib lub voj voog ib ob, yog siv rau ntsuas moos ceev . Nyob rau hauv cov ntaub ntawv ntawm lub computer moos ceev , ib hertz sib npaug ib zuam ib ob. Lub moos ceev ntawm khoos phis tawj feem ntau yog ntsuas hauv megahertz (MHz) lossis gigahertz (GHz).
