Cov ceev nrog qhov twg cov ntaub ntawv canbe kis tau los ntawm ib lub cuab yeej mus rau lwm tus. Cov ntaub ntawv tus nqi feem ntau ntsuas hauv megabits (million bits) ormegabytes (million bytes) ib ob. Cov no feem ntau yog abbreviatedas Mbpsand MBps, ntsig txog. Lwm lub sij hawm rau cov ntaub ntawv Transferrateis nce.
Ib yam li ntawd, tib neeg nug, uas yog ib chav tsev ntawm cov ntaub ntawv xa mus?
Hauv kev sib txuas lus cov ntaub ntawv , bits persecond (abbreviated bps lossis me ntsis / sec) yog ib qho kev ntsuas ntawm cov ntaub ntawv ceev rau computer modems thiab kis tau tus mob cov neeg nqa khoom. Raws li cov lus qhia, qhov ceev hauv bps yog sib npaug rau cov lej ntawm cov khoom kis tau los yog tau txais txhua thib ob. Loj dua units yog qee zaum siv los qhia siab cov ntaub ntawv ceev.
Dab tsi yog qhov ceev ntawm kev xa cov ntaub ntawv hauv cheeb tsam hauv cheeb tsam network? Hauv kev sib txuas lus, hloov ntaub ntawv isusually ntsuas nyob rau hauv me ntsis ib ob. Piv txwv li, typicallow- kev sib txuas ceev rau hauv Internet tej zaum yuav yog 33.6 kilobits persecond (Kbps). Hauv Ethernet hauv zos networks , kev hloov ntaub ntawv tuaj yeem ceev li 10 megabits persecond.
Hauv qhov no, cov ntaub ntawv ceev ntsuas li cas?
Kev ntsuas ntawm Cov Ntaub Ntawv Ceev Cov Ntaub Ntawv hloov ceev canbe ntsuas nyob rau hauv ib tug thib ob, los yog bytes ib ob. Abyteis (feem ntau) 8 ntsis ntev.
Mbps yog dab tsi?
Megabits ib ob ( Mbps ) yog ib qho kev ntsuas rau bandwidth thiab throughput ntawm lub network. Txhua megabitis sib npaug li 1 lab khoom. Mbps belongs rau familyofmetrics siv los ntsuas lub peev xwm thiab ceev ntawm datatransfer.

Dab tsi yog qhov sib txawv ntawm pab pawg cov ntaub ntawv thiab cov ntaub ntawv tsis yog pawg?
Ob leeg yog cov ntaub ntawv muaj txiaj ntsig ntawm cov ntaub ntawv tab sis qhov sib txawv ntawm lawv yog cov ntaub ntawv tsis muaj ntaub ntawv yog rawdata. Qhov no txhais tau hais tias nws nyuam qhuav tau sau tab sis tsis txheeb rau hauv ib pawg lossis cov chav kawm. Ntawm qhov tod tes, groupeddata yog cov ntaub ntawv uas tau teeb tsa ua pawg los ntawm cov ntaub ntawv nyoos
Tus qauv twg yog siv los hloov cov ntaub ntawv kho mob thiab kev tswj hwm ntawm ntau lub tsev kho mob cov ntaub ntawv xov xwm HIS)?
Kev Noj Qab Haus Huv Qib Xya lossis HL7 yog hais txog cov txheej txheem thoob ntiaj teb rau kev hloov pauv cov ntaub ntawv kho mob thiab kev tswj hwm ntawm cov ntawv thov software siv los ntawm ntau tus kws kho mob. Cov qauv no tsom rau cov txheej txheem thov, uas yog 'txheej 7' hauv OSI qauv
Yuav ua li cas rau txim nyob rau hauv Is Nrias teb rau nyiag computer cov ntaub ntawv cov cuab tam los yog tej software qhov chaw code los ntawm ib tug neeg lub koom haum los yog los ntawm lwm yam txhais tau tias?
Kev piav qhia: Kev rau txim hauv Is Nrias teb rau kev nyiag cov ntaub ntawv hauv computer, cov khoom muaj nqis lossis ib qho software cov cai los ntawm ib lub koom haum, ib tus neeg, lossis los ntawm lwm txoj kev yog raug kaw 3 xyoo thiab raug nplua ntawm Rs. 500,000
Dab tsi yog qhov sib txawv ntawm qhov ntsuas qhov ntsuas thiab qhov ntsuas thib ob?
Primary index: nyob rau hauv ib tug sequentially order file, qhov Performance index uas nws search key qhia cov sequential order ntawm cov ntaub ntawv. Kuj hu ua clustering index. Secondary index: ib qho Performance index uas nws qhov tseem ceeb tshawb nrhiav qhia qhov kev txiav txim sib txawv ntawm qhov kev txiav txim ntawm cov ntaub ntawv. Kuj hu ua non-clustering index
Dab tsi yog qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas?
Xav txog nws li no: rhiab heev yog ib qho kev ntsuas ntawm qhov hloov pauv ntawm lub koob yees duab qhov chaw saib uas tsim nyog raws li qhov muaj peev xwm tshawb pom, thiab qhov pib yog qhov ntau npaum li cas ntawm cov lus tsa suab yuav tsum tshwm sim txhawm rau txhawm rau ua rau lub tswb
