Ob-dimensional kev sib haum xeeb kuaj ua tau ntes thiab yog lawm tag nrho ib qho yuam kev thiab ntes ob thiab peb yuam kev uas tshwm sim nyob qhov twg hauv matrix.
Yog li ntawd, pes tsawg qhov yuam kev tuaj yeem kuaj pom?
Hamming cov lej tuaj yeem ntes tau mus txog rau ob-ntsis yuam kev los yog kho ib-ntsis yuam kev tsis muaj kuaj pom ntawm tsis raug yuam kev . Ntawm qhov sib txawv, qhov yooj yim parity code kho tsis tau yuam kev , thiab tuaj yeem ntes tau tsuas yog tus lej khib ntawm cov khoom hauv yuam kev.
Tom qab ntawd, lo lus nug yog, parity puas kho qhov yuam kev? Parity bits Nws yog ib txoj kev yooj yim heev uas ua tau siv los ntes ib leeg lossis lwm tus lej khib (piv txwv li, peb, tsib, thiab lwm yam) ntawm yuam kev hauv cov zis. Ib tus lej ntawm flipped khoom yuav ua cov kev sib haum xeeb me ntsis tshwm yog lawm txawm tias cov ntaub ntawv yuam kev.
Ua raws li qhov no, koj yuav txiav txim siab li cas ib qho yuam kev me ntsis?
Qhov yooj yim tshaj plaws txoj kev mus ntes a ib me ntsis yuam kev hauv 4- me ntsis code yog siv parity checking, nyob rau hauv cov ntaub ntawv uas ib tug ntxiv me ntsis yuav tsum tau ntxiv (parity me ntsis ).
Yuav ua li cas kho qhov yuam kev siv cov parity codes?
Mus ntes thiab yog lawm qhov yuam kev, cov khoom ntxiv tau ntxiv rau cov ntaub ntawv me me thaum lub sijhawm xa khoom. Cov khoom ntxiv yog hu ua kev sib haum xeeb me ntsis. Lawv tso cai kuaj pom los yog kho ntawm qhov yuam kev. Cov ntaub ntawv me me nrog nrog tus kev sib haum xeeb bits ib code lus.

Koj puas tuaj yeem muaj nyob rau hauv ib qho kev tshaj tawm? cov lus teb yog "tsawg kawg 12." txhawb ntxiv. ntawm saj, tab sis muaj qhov txwv. Muaj ob theem ntawm kev taw qhia (tus taw tes rau tus taw tes rau ib yam dab tsi) yog qhov ntau
Muaj pes tsawg tus yuam sij zoo ib yam tuaj yeem muaj phau ntawv txhais lus muaj Python?
Tus yuam sij txheeb xyuas lub ntsiab lus ntawm phau ntawv txhais lus, tus nqi yog cov ntaub ntawv sib raug rau tus yuam sij muab. Cov txiaj ntsig tseem ceeb yog qhov tshwj xeeb, i. e. tsis tuaj yeem muaj ob tus yuam sij zoo ib yam hauv phau ntawv txhais lus
Dab tsi yog qhov sib txawv loj ntawm kev txheeb xyuas qhov yuam kev thiab kev kho cov lej yuam kev?
Ob qhov kev tshawb nrhiav qhov yuam kev thiab kev kho qhov yuam kev yuav tsum muaj qee qhov ntawm cov ntaub ntawv rov qab xa mus nrog cov ntaub ntawv tiag tiag; kev kho yuav tsum muaj ntau tshaj li kev tshawb nrhiav. Parity bits yog ib txoj hauv kev yooj yim rau kev tshawb nrhiav qhov yuam kev. Ib qho parity me ntsis yog ib qho ntxiv me ntsis xa nrog cov ntaub ntawv uas tsuas yog 1-ntsis suav ntawm cov ntaub ntawv
Vim li cas kev cob qhia yuam kev tsawg dua qhov kev xeem yuam kev?
Kev cob qhia yuam kev feem ntau yuav tsawg dua qhov kev xeem yuam kev vim tias tib cov ntaub ntawv siv los ua kom haum tus qauv yog ua haujlwm los ntsuas nws qhov kev kawm yuam kev. Ib feem ntawm qhov tsis sib xws ntawm qhov kev cob qhia yuam kev thiab qhov kev xeem yuam kev yog vim tias cov txheej txheem kev cob qhia thiab cov ntawv xeem muaj qhov sib txawv ntawm cov khoom siv
Muaj pes tsawg cov khoom nyob hauv ib byte pes tsawg tus nibbles nyob hauv ib byte?
Txhua 1 lossis 0 hauv tus lej binary raug hu ua me ntsis. Los ntawm qhov ntawd, ib pawg ntawm 4 cov khoom hu ua nibble, thiab 8-ntsis ua ib byte. Bytes yog ib tug zoo nkauj buzzword thaum ua hauj lwm nyob rau hauv binary
