Khoos phis tawj tshuab raws li lub tswvyim ntawm lub ntsis
Ib tus lej binary, lossis me ntsis, yog qhov tseem ceeb tshaj plaws thiab tsawg tshaj plaws ntawm cov ntaub ntawv hauv kev suav. Ib qho me ntsis nruab nrab yog ib qho ntawm ob qhov kev ntsuas binary, ib qho "0" los sis "1." Cov kev ntseeg no tseem tuaj yeem sawv cev rau qhov tseem ceeb ntawm "log" lossis "tawm" thiab "muaj tseeb" lossis "tsis tseeb." Lub tsev ntawm me ntsis tuaj yeem sawv cev los ntawm ib tug lowercase b .
Khoom hauv Networking
Hauv kev sib tham , cov khoom me me yog siv cov hluav taws xob hluav taws xob thiab pulses ntawm lub teeb uas raug xa mus los ntawm lub computer network. Qee qhov kev sib txuas lus hauv network xa thiab tau txais cov ntaub ntawv hauv daim ntawv teev me ntsis. Cov no yog hu ua cov kev cai lij choj ntsis. Piv txwv ntawm cov txheej txheem me ntsis-oriented muaj qhov point-to-point protocol.
Networking speeds yog feem ntau hais rau hauv cov khoom-ib-thib ob, Piv txwv li, 100 megabits = 100 lab khoom rau ib pliag, uas tuaj yeem hais tias yog 100 Mbps.
Khoom thiab Bytes
Ib tug byte yog ua los ntawm yim khoom ua ke. Tej zaum koj yuav paub ib tus byte los ntawm ib qho kev ntsuas me me los sis tus nqi ntawm RAM hauv computer. Tus byte tuaj yeem sawv cev rau ib tsab ntawv, ib tug xov tooj lossis ib lub cim, lossis lwm yam ntaub ntawv ntawm lub computer lossis qhov kev pab cuam siv tau.
Bytes yog sawv cev los ntawm ib qho loj B.
Siv Cov Khoom Tom
Txawm hais tias lawv muaj qee zaum sau hauv decimal lossis byte form, cov chaw nyob network xws li tus IP chaw nyob thiab MAC chaw nyob yog qhov kawg hauv cov khoom sib txuas lus hauv network.
Qhov tob xim hauv cov duab graphics feem ntau ntsuas ntawm cov khoom. Piv txwv, monochrome dluab yog cov dluab ib ntsis, thaum 8-ntsis dluab tuaj yeem sawv cev 256 xim lossis gradients hauv grayscale. Muaj tseeb xim graphics muaj nyob rau hauv 24-ntsis, 32-ntsis, thiab ntau dua graphics.
Cov naj npawb tshwj xeeb cov zauv hu ua "yawm sij" yog siv los encrypt cov ntaub ntawv ntawm computer networks. Qhov ntev ntawm cov yuam sij no yog hais txog cov khoom tsawg. Qhov ntau dua cov khoom, qhov zoo tshaj ntawd qhov tseem ceeb yog tiv thaiv cov ntaub ntawv. Hauv kev ruaj ntseg wireless network, piv txwv, 40-ntsis WEP cov yawm sij ua pov thawj kom tsis muaj kev ruaj ntseg, tab sis cov kev siv 128-ntsis los yog loj dua WEP siv hnub no zoo dua.
