Feem ntau muaj ob hom ntawm multiplexers, uas yog analog thiab digital. Lawv tau muab faib ua ntu ntu ntu Multiplexing (FDM), Wavelength Division Multiplexing (WDM), thiab Time Division Multiplexing (TDM). Cov duab hauv qab no muab cov lus qhia ntxaws txog qhov kev faib tawm no.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog multiplexing hauv computer network?
Hauv kev sib txuas lus thiab computer networks , multiplexing (qee zaum tau cog lus rau muxing) yog ib txoj hauv kev uas ntau yam analog lossis digital signals tau muab tso ua ke rau hauv ib lub teeb liab ntawm qhov nruab nrab sib koom. Lub hom phiaj yog los qhia cov peev txheej tsawg. Cov Multix ua teeb liab kis tau los ntawm kev sib txuas lus xws li cable.
Multiplexing yog dab tsi thiab vim li cas nws thiaj siv? Multiplexing yog cov txheej txheem kev sib tham nrov uas sib koom ua ke ntau yam analog thiab digital signals rau hauv lub teeb liab kis tau los ntawm kev sib koom nruab nrab. Multiplexers thiab de-multiplexers yog siv hloov ntau lub teeb liab rau hauv ib lub teeb liab. Qhov ntawd yog, ntau tshaj ib qho kev hu xov tooj yog kis tau los ntawm ib qho nruab nrab.
Tsis tas li ntawd, plaub yam tseem ceeb ntawm multiplexing yog dab tsi?
Lub sij hawm faib multiplexing yog faib ua plaub hom:
- Synchronous lub sij hawm faib multiplexing.
- Asynchronous lub sij hawm faib multiplexing.
- Interleaving time-division multiplexing.
- Statistical time-division multiplexing.
Qhov twg yog multiplexing siv?
Frequency Division Multiplexing FDM yog siv feem ntau yog rau kev sib kis analog. Nws tuaj yeem yog siv nyob rau hauv ob qho tib si wired thiab wireless nruab nrab. Ib qho piv txwv ntawm daim ntawv thov uas siv FDM yog FM xov tooj cua. FM yog ib pawg uas nyob ntawm ntau zaus ntawm 88 MHz txog 108 MHz nyob rau hauv lub xov tooj cua loj dua spectrum.

Social engineering yog dab tsi thiab nws lub hom phiaj yog dab tsi?
Social engineering yog lo lus siv rau ntau yam kev ua phem ua phem uas ua tiav los ntawm tib neeg kev sib cuam tshuam. Nws siv kev puas siab puas ntsws los ntxias cov neeg siv kom ua yuam kev kev ruaj ntseg lossis muab cov ntaub ntawv rhiab
Tus neeg tua neeg OOM yog dab tsi thaum nws khiav thiab nws ua dab tsi?
OOM Killer ua haujlwm los ntawm kev tshuaj xyuas tag nrho cov txheej txheem khiav thiab muab lawv cov qhab nia phem. Cov txheej txheem uas tau qhab nia siab tshaj yog tus uas raug tua. OOM Killer muab cov qhab nia ua phem raws li ntau yam
Kev tshawb xyuas network yog dab tsi thiab nws ua li cas thiab vim li cas nws thiaj xav tau?
Network auditing yog txheej txheem uas koj lub network tau teeb tsa ob qho tib si ntawm software thiab kho vajtse. Cov txheej txheem tuaj yeem ua rau poob siab yog tias ua tiav manually, tab sis hmoov zoo qee cov cuab yeej tuaj yeem pab automate ib feem ntawm cov txheej txheem. Tus thawj coj yuav tsum paub tias lub tshuab thiab cov cuab yeej txuas nrog lub network li cas
Dab tsi yog hom ntaub ntawv thiab piav qhia nws hom?
Hom ntaub ntawv. Ib hom ntaub ntawv yog hom ntaub ntawv. Qee cov ntaub ntawv muaj xws li cov lej, cov lej ntab, cov cim, cov hlua, thiab cov arrays. Tej zaum lawv kuj yuav yog hom tshwj xeeb, xws li hnub tim, timestamps, boolean qhov tseem ceeb, thiab varchar (tus cwj pwm txawv)
Dab tsi yog tus hais lus sau nws lub hom phiaj thiab dab tsi yog yam tseem ceeb uas yuav tsum nco ntsoov txog cov lus hais?
Cov neeg hais lus sau ntawv yog cov ntawv qhia uas tus neeg nthuav qhia siv thaum nthuav qhia qhov kev nthuav qhia. Lawv pab tus neeg nthuav qhia nco txog cov ntsiab lus tseem ceeb thaum muab kev nthuav qhia. Lawv tshwm sim ntawm tus swb thiab tuaj yeem pom tsuas yog los ntawm tus tshaj tawm thiab tsis yog cov neeg tuaj saib
