Tam sim no, ntau tus neeg siv Is Taws Nem siv cov ntaub ntawv. Thaum rub tawm cov ntsiab lus, cov lus nug tshwm sim ntev npaum li cas nws yuav siv sijhawm ntev los rub tawm cov ntawv, thiab thaum saib yeeb yaj kiab online, koj txaus siab rau qhov ceev ntawm Internet txuas yuav tsum yog rau saib zoo. Txhawm rau xam qhov no, koj yuav tsum paub dab tsi thiab khoom bytes thiab muaj peev xwm hloov kilobytes rau megabits.
Cov Lus Qhia
Kauj ruam 1
Bit (Askiv Binary digIT - lub cim binary, lossis me ntsis - me ntsis) - lub tsev kawm ntawv qib qis lub cim xeeb siv los khaws ib qho ntawm cov cim ntawm binary code. Nws yog hu ua tus nqi qis kawg ntawm kev hloov cov ntaub ntawv. Kev sib xyaw me ntsis tuaj yeem sawv cev rau tus yam ntxwv, toggle, lossis xa cov cim. Cov khoom siv yog siv los txhais cov ntaub ntawv rau hauv cov kab lus ntawm cov cim uas tuaj yeem ua tiav los ntawm lub koos pis tawj. Cov ntaub ntawv no hu ua cov ntaub ntawv me ntsis.
Kauj ruam 2
Ib byte (BinarY TErm - binary lub sij hawm, binary expression) yog qhov cim xeeb ywj pheej uas khaws cov ntaub ntawv sau rau nws. A byte muaj 8 khoom. Cia peb xav txog dab tsi yog kilobytes thiab megabits thiab yuav ua li cas los rov txheeb lawv. Hauv lwm lo lus, cia peb txheeb xyuas seb koj tuaj yeem hloov kilobytes rau megabits li cas.
Kauj ruam 3
Hauv lub ntiaj teb SI system ntawm kev ntsuas, cov cim ua ntej kilo-, mega - txhais tau tias 1000 thiab 100000, feem. Tab sis rau kev ceev ntawm cov ntaub ntawv hloov khoom, qhov no tsis yog qhov tseeb. Hauv kev lag luam khoos phis tawm, nws ib txwm pom zoo tias qhov pib ntawm qhov kilo- sawv rau 1024, yog li ntawd, megabytes yog 1024 * 1024 = 1048576. Yog li ntawd muaj pes tsawg kilobytes muaj nyob rau hauv megabit? Cia peb ua kev xam. Ua ntej, peb suav seb muaj pes tsawg qhov me me hauv 1 kilobyte 1 kilobyte = 1024 bytes = 1024 * 8 = 8192 khoom.
Kauj ruam 4
Tam sim no cia peb hloov cov khoom me me rau megabits. Ua li no, faib cov lej tshwm sim los ntawm tus lej sib npaug nrog rau prefix mega. 8192/1048576 = 0, 0078125 megabits. Ua ke ua ke nrog kev suav sau, peb tuaj yeem hais tias 1 kilobyte = 0, 0078125 megabits. Los yog 1KB = 0, 0078125Mb.
