Yuav ua li cas yog buffering: cov ntsiab lus

Buffering - yog ib txoj kev sib koom lub koom haum, namely, lub tswv yim thiab tso zis ntawm cov ntaub ntawv nyob rau hauv koj laij pab kiag li lawm thiab computers. Qhov tsis zoo yog siv raws li ib qho chaw rau ib ntus khaws cia cov ntaub ntawv. Thaum lub sij hawm ib tug cov ntaub ntawv tswv yim ntaus ntawv tsim cov ntaub ntawv teev rau hauv tus tsis, thaum lwm tus neeg ua nyeem cov ntaub ntawv los ntawm qhov tsis zoo ua. Nyob rau hauv lub derivation ntawm tag nrho cov caij nyoog rov qab.

Qhov uas peb ntsib nrog buffering?

Zoo tag nrho cov dab nyob rau hauv lub PC yog kev cob cog rua nrog no cov txheej txheem. Uninformed neeg no tsis yog ib qho yooj yim to taub dab tsi yog buffering. Txawm li cas los, nws yog ib qho yooj yim mus soj ntsuam: cov tib movie downloads online - cov ntaub ntawv yog buffered, cov zaj duab xis yog loaded rau hauv lub cache, thiab kev ua si, txawm hais tias nws nyob rau hauv koj lub computer los yog tsis.

Qhov no lub lag luam tso cai dab ua cov ntaub ntawv tawm tswv yim thiab tso zis ntawm nws tus kheej. Tsaug rau no nws usefulness, buffering yog siv nyob rau hauv multi-OS.

Ob peb ntawm nws cov hom yog siv nyob rau hauv computer graphics rau cov tswv yim, tso zis, thiab cov duab ua. Lawv siv nyob rau hauv kev kho vajtse los yog software tshwm sim.

Ib qho piv txwv ntawm buffering nyob rau hauv lub kho vajtse yog ib tug modem operative nco, uas yog siv rau ib ntus khaws cia rau hauv lub xa thiab tau txais cov ntaub ntawv.
Ib qho piv txwv ntawm buffering nyob rau hauv lub software yog ib tug multitasking operating system, nyob rau hauv uas cov ntaub ntawv nkag teb chaws sau yog ib ntus download ntaub ntawv nyob rau hauv lub sau queue.

Advanced computer cov neeg siv yuav tsum paub hais tias xws li buffering.
Nyob rau hauv lub teb ntawm cov ntaub ntawv technology muaj yog ib txwm ib tug saum npoo thiab nyob rau hauv-tob ntxiv. To taub hais tias xws li buffering, koj yuav mus ntxiv thiab xav paub ntxiv kev saib xyuas ntawm nws tus kheej lub hom.

Nws yog lub npe hu hais tias muaj ob thiab triple buffering. Nyob rau lawv yuav tsum tau tham nyob rau hauv lub tom ntej no subtitle.

Triple buffering - yog dab tsi?

Nyob rau hauv computer graphics, hom txheej txheem yog los sib tham ntau yam ntawm ob buffering. Qhov txawv tsuas yog nyob rau hauv cov qauv ntawm cov zaub dluab. Triple tsis txhob los txo tus naj npawb ntawm artifacts. Tsis tas li ntawd, cov kev sib txawv ntawm ob thiab triple buffering cai nyob rau hauv lub tso zis ceev ntawm daim duab.

Triple buffering txoj kev thiab yog synchronized nrog ib tug refresh tus nqi. Qhov thib peb tsis yog siv no raws li ib tug txoj kev muab chaw rau kev hloov kev thov nyob rau hauv tag nrho cov ntim ntawm cov zis graphics. Nws ua raws li ib yam ntawm cov khw. triple buffering txoj kev yuav tsum ntau yam kev pab, tab sis muab ib tug zoo ib yam ncej nqi.

Peb tsis - nws tsis txwv tus xov tooj. Txawm li cas los, qhov yuav tsum tau rau 4 los yog ntau tshaj qhov chaw rau lub ib ntus cia ntawm Uploaded cov ntaub ntawv yog tsis muaj kev koom ua hauj lwm yeej yuav xwb 3 ntawm lawv. Yog li ntawd, qhov zoo tshaj plaws kev xaiv - triple buffering.

Xav txog dab tsi yog buffering nyob rau hauv cov kev ua si?

Yuav kom hloov dluab ntawm kev ua si kuj siv buffering. Tus ua si siv raws li ib tug muab ob npaug rau, thiab triple. Ob chav buffering yog siv rau ib tug tsawg-xaus PCs thiab kev khiav hauj lwm systems, thaum lub sij hawm triple - rau ntau haib.

Yog hais tias koj siv triple buffering rau tus qaug OS, qhov kev ua si yuav tsis. Nyob rau hauv lwm yam lus, nyob rau zoo li cas ntawm txoj kev yog siv nyob rau hauv koj lub computer nyob rau qhov kev kawm. Ua si, dhau lawm, yog sib txawv, nrog txawv uas yuav tsum tau rau ib lub PC thiab OS.

Xaiv hom uas tsis yog es nyuaj, raws li qhov kev ua si makers tsim lawv cov offspring, siv ib tug ntau yam ntawm txoj kev. Yog li ntawd, ib tug yuav tau hnov nyob rau hauv gaming forums txog yuav ua li cas ib tug tej yam kev ua si tsis ua hauj lwm nrog cov triple buffering, thiab vice versa.

Qhov tseeb tiag mas, manufacturers yuav tsum qhia tias cov kev uas yuav tsum ntawm qhov kev ua si, nws cov compatibility nrog txawv operating systems, buffering them nyiaj yug, thiab hais txog. D.

Yog hais tias lub chaw tsim tshuaj paus tsis muab tej lus txog cov compatibility, nws yog tau mus xyuas nws tus kheej. Nyob rau hauv txhua rooj plaub, siv tsuas lub sij hawm, lub computer yog tsis muaj kev tsim txom yuav tsis coj. Incompatibility yuav pom yuav luag tam sim ntawd, raws li nws pom nyob rau hauv lub braking graphical visualization thiab cov neeg pluag dluab nrog lub suab synchronization.

Hais txog zis buffering

Tso zis buffering - ib tug heev pab tau tshaj plaws. Qhov no muaj nuj nqi yog lub stacking ntawm tag nrho cov zis hauv lub tsab ntawv, ntxiv ib cov kua nplaum rau cov header thiab lwm yam uas ua los ntawm lub chaw ua hauj lwm ntawm ib tug tsab ntawv. Tom qab kawm tiav ntawm kev ntawm cov ntaub ntawv, tag nrho cov ntaub ntawv xa mus rau tus neeg nyob rau hauv lub rov qab txiav txim, piv txwv li lub thawj headers, ces cov nplooj ntawv thiab ces tus tshwm sim ntawm cov tsab ntawv.

Cov Tsam Thawj muaj los ntawm tso zis buffering

1. Ua ib tug khoom qab zib los ntawm kiag li nyob qhov twg nyob rau hauv tsab ntawv.
2. Thaum pib ntawm qhov kev sib kho thaum twg los tau lub sij hawm.
3. Compressing cov ntaub ntawv ua ntej yuav xa nws mus rau tus neeg.

Nws yuav tsum tau nco ntsoov tias compression yuav tsum tau ntxiv CPU kev pab. Tab sis hloov speeds yuav nce mus rau 40% (nyob ntawm seb tus xov tooj ntawm cov dluab thiab cov ntawv nyeem). Nws yog lub npe hu hais tias cov duab no yog compressed tsawg npaum li cas cov ntawv nyeem. Lub neej ntawd tso zis buffering yog tsis enabled.

Muaj 2 txoj kev mus rau pab kom cov zis buffering:

1. Haum rau leej twg leej twg muaj cov neeg rau zaub mov nws tus kheej, los yog leej twg muaj kev nkag tau mus rau lub php.ini cov ntaub ntawv. Tag nrho cov uas yuav tsum tau yog pom nyob rau hauv cov ntaub ntawv no output_buffering qhia thiab cob ib tug nqi rau Nyob rau.
2. Qhov thib ob hom yog siv ob_start () nyob rau hauv tsab ntawv, tso zis rau ntawm cov uas yuav tsum tau buffered.

Ntawm no yog peb hais nrog lub fact tias xws li buffering.
