ZIP vs 7Z vs ZSTD: Qhov twg yog qhov zoo tshaj plaws compression hom rau luam thiab xa?

Khaws thiab xa cov ntaub ntawv loj yuav tsis zoo ib yam yam tsis muaj kev siv compression thiab cov kev pab cuam. Ua tsaug rau cov cuab yeej no, nws tuaj yeem txo lawv mus rau ob peb gigabytes lossis megabytes kom yooj yim thiab yooj yim cia lossis xa. Tab sis dab tsi yog qhov zoo tshaj plaws compression hom rau luam thiab xa? Hauv tsab ntawv no, peb piv peb: ZIP vs 7Z vs ZSTD thiab peb yuav qhia koj thaum twg ib lossis lwm qhov zoo tshaj..

Xaiv qhov zoo tshaj plaws compression hom ntawv rau luam thiab xa

Txo qhov loj ntawm cov ntaub ntawv digital yog qhov tseem ceeb thaum txuag lossis sib koom lawv. Qhov no ua tau ua tsaug rau compression, txheej txheem uas siv algorithms rau pab pawg cov ntaub ntawv nyob rau hauv nws qhov tsawg tshaj plaws tau qhiaQhov tshwm sim yog cov ntaub ntawv me dua li qhov qub, tso cai rau nws yooj yim xa los ntawm kev xa ntawv lossis lwm txoj kev, lossis khaws cia tsis tas siv ntau qhov chaw.

Ntau cov ntaub ntawv ntawm ntau hom tuaj yeem compressed rau hauv ib cov ntaub ntawv nrog ib hom ntawv. Tau kawg, Muaj ntau hom compression sib txawv, txhua tus nrog nws tus kheej peculiarities.. Thiab yog vim li cas nws tseem ceeb heev kom paub yuav ua li cas xaiv qhov zoo tshaj plaws compression hom ntawv luam thiab xa.

Nws yuav tsum tau muab sau tseg tias compression hom tsis tsuas yog cuam tshuam rau lub qhov kawg cov ntaub ntawv loj. Nws kuj txiav txim siab qhov compatibilidad nrog sib txawv systems, nrog rau cov ceev thiab zoo ntawm compression thiab decompressionQee hom compression sawv tawm rau lawv qhov ceev; lwm tus rau lawv versatility. Peb ntawm cov hom nrov tshaj plaws thiab siv dav peb yuav muab piv rau hauv cov ncej no: ZIP vs. Z7 vs. ZSTD.

ZIP: Universal Standard

Txhawm rau pab koj xaiv hom compression zoo tshaj plaws rau kev luam thiab xa, cia peb pib nrog tus hlob: ZIPTsim nyob rau hauv 1989 los ntawm Phil Katz, nws sai sai dhau los ua tus qauv rau kev sib koom cov ntaub ntawv compressed. Nrog rau ntau xyoo ntawm kev paub, nws yog nyob deb ntawm qhov zoo tshaj plaws-paub thiab feem ntau siv compression hom.

Zoo

Nws lub ntsiab kom zoo dua yog cov compatibilidad uas muaj: Windows, macOS, Linux, Android, iOS… Txhua lub tshuab ua haujlwm niaj hnub tuaj yeem qhib ZIP cov ntaub ntawv yam tsis muaj software ntxiv. Yog li ntawd, yog tias koj xa cov ntaub ntawv hauv hom no, koj tuaj yeem ua tau 99,9% tseeb tias tus neeg txais yuav tuaj yeem qhib nws.

Lwm qhov kev pom zoo yog qhov ZIP compresses txhua cov ntaub ntawv hauv lub thawv ntawm nws tus kheejQhov no txhais li cas? Yog tias qhov kawg archive ua corrupted, nws muaj peev xwm txuag tau cov ntaub ntawv tsis muaj kev cuam tshuam hauv nws. Rau tib lub laj thawj, ZIP tso cai rau koj rho tawm cov ntaub ntawv tus kheej yam tsis tas yuav unzip tag nrho cov pob.

Cov Kev Txwv

ZIP hom lub ntsiab tsim txiaj tseem yog nws qhov tsis muaj zog tshaj plaws: vim tias nws yog qub, nws siv cov compression algorithms tsawg dua. Qhov no txhais tau tias cov ntaub ntawv kawg yog loj dua tshaj li cov uas tuaj yeem tau txais kev siv cov kev xaiv niaj hnub no. Ntxiv rau, tus qauv ZIP hom ntawv tsuas txhawb cov ntaub ntawv mus txog 4 GB, vim nws siv 32-ntsis chaw nyob. Txhawm rau nthuav cov ntaub ntawv loj dua, koj yuav tsum siv nws ntau dua "niaj hnub", ZIP6.

Puas yog ZIP yog hom compression zoo tshaj plaws rau kev luam thiab xa?

• ZIP hom yog koj qhov kev xaiv zoo tshaj yog tias koj saib xyuas ntau dua tus neeg txais tuaj yeem qhib cov ntaub ntawv yooj yim.
• Nws yog qhov zoo tagnrho rau xa cov ntaub ntawv, kev nthuav qhia lossis ob peb daim duab los ntawm email.
• Nws kuj pab rau luam ntawv lossis thaub qab, tsuav yog qhov chaw cia tsis yog qhov teeb meem tseem ceeb.
• Txawm li cas los xij, yog tias koj tab tom nrhiav qhov siab tshaj plaws compression thiab cov yam ntxwv siab heev, sim nws cov kev xaiv.

7Z: Qhov siab tshaj plaws compression thiab yooj

Yog tias koj tab tom nrhiav rau qhov zoo tshaj plaws compression hom ntawv rau kev luam thiab xa, koj yuav tau ntse mus xyuas 7Z hom. Qhov no yog qhov haiv hom ntawv dawb thiab qhib qhov software 7- ZIP chaw, tsim los ntawm Igor Pavlov hauv 1999. Vim li cas nws thiaj li sawv tawm? Vim nws siv ntau niaj hnub thiab nruj compression algorithms, qhov tseem ceeb tshaj plaws yog LZMA2. Cia peb saib nws qhov zoo thiab qhov tsis zoo.

Zoo

Qhov txiaj ntsig tseem ceeb ntawm 7Z yog tias nws muaj qhov sib piv ntau dua. Feem ntau, 7Z nrog LZMA2 tsim cov ntaub ntawv ntawm 30% thiab 70% me dua ZIPQhov no yog qhov zoo dua yog tias koj thaub qab ntau cov ntaub ntawv thiab xav txuag chaw cia.

Lwm qhov zoo ntawm 7Z yog tias nws muaj cov kev xaiv siab heev, xws li khoom compression, uas tso cai rau koj kom tau txais cov ntaub ntawv me me. Nws kuj muaj kev txhawb nqa rau cov ntaub ntawv loj, kev ruaj ntseg xaiv xws li AES-256 encryption, thiab kev txhawb nqa rau ntau yam compression algorithms (BZip2, PPMd thiab lwm yam).

Cov Kev Txwv

Yeej, 7Z muaj ob qhov kev txwv loj. Ntawm ib sab, Kev khiav hauj lwm systems tsis muaj haiv neeg txhawb nqa rau 7Z hom. Hauv lwm lo lus, tus neeg txais yuav tsum tau nruab ib qhov kev pab cuam zoo li 7-Zip lossis ib qho ntawm nws txoj kev xaiv los qhib cov ntaub ntawv.

Lwm qhov tsis zoo yog qhov hom hom ntawv no xav tau ntau lub sij hawm thiab kev pab cuam rau compression thiab decompression. Nws yog to taub, vim nws yog ib qho ntawm cov haib tshaj plaws rau txo cov ntaub ntawv loj. Txawm li cas los xij, ntawm cov khoos phis tawj qub lossis cov uas muaj peev txheej tsawg, qhov no tuaj yeem yog teeb meem.

Puas yog 7Z yog hom compression zoo tshaj plaws rau kev luam thiab xa?

• Rau cov ntawv luam nws yog qhov zoo tagnrho, tshwj xeeb tshaj yog yog tias koj muaj chaw me me cia.
• Nws kuj yog ib qho kev xaiv zoo yog tias koj xav tau los tiv thaiv koj cov ntaub ntawv nrog encryption.
• Zoo meej rau kev xa cov ntaub ntawv ntev npaum li tus neeg tau txais kev paub yuav ua li cas los tswj cov hom ntawv.

ZSTD (Zstandard): Niaj hnub nimno thiab sai dua

ZSTD (Zstandard) tej zaum yuav tsis yog hom compression zoo tshaj plaws rau kev luam thiab xa, tab sis nws nyob ze. Tus neeg tshiab no tau tsim los ntawm Facebook (tam sim no Meta) hauv 2015. Nws tsis yog lub thawv hom, zoo li ZIP lossis 7Z, tab sis compression algorithm. Yog li ntawd, nws tsis tsuas yog tso cai rau koj los tsim cov pob khoom (.tar), tab sis kuj tseem tuaj yeem muab tso rau hauv lwm cov cuab yeej hauv online, xws li cov servers, cov ntaub ntawv ntws, lossis cov thaub qab tsis siv neeg.

Zoo

ZSTD qhov tseem ceeb tshaj plaws yog nws hellish ceev, tshwj xeeb tshaj yog rau decompression. Nws tuaj yeem ntim cov ntaub ntawv ntawm qhov nrawm ntawm gigabytes ib ob, sai dua ZIP lossis 7Z.

Ntawm qib compression, ZSTD muaj peev xwm ua tiav qhov sib piv ze heev rau 7Z, thiab nrog ntau dua speeds. Nws kuj tso cai rau koj xaiv qhov compression ceev kom qhov tseem ceeb ntawm cov ntaub ntawv ncaj ncees.

Cov Kev Txwv

Ua tus tshiab tshaj plaws, nws muaj a qis dua compatibility tshaj lwm yam. Qhov tseeb, nws muaj kev txhawb nqa zoo dua ntawm Linux dua li ntawm Windows thiab macOS, qhov twg cov software tshwj xeeb lossis cov kab hais kom ua yuav tsum tau tswj hwm nws. Rau tib lub laj thawj, nws yog tsis heev intuitive rau cov neeg siv nruab nrab.

Puas yog ZSTD yog hom compression zoo tshaj plaws rau kev luam thiab xa?

• Yog tias koj tab tom nrhiav qhov siab tshaj plaws ceev, ZSTD yog hom compression zoo tshaj plaws rau kev luam thiab xa.
• Zoo meej rau thaub qab servers lossis databases.
• Zoo tagnrho rau cov kev faib cov pob khoom software.
• Qhov zoo tshaj plaws kev xaiv rau ceev compression thiab decompression nyob rau hauv kev loj hlob ib puag ncig.
