Yintoni kumthamo: Iinkcukacha

Komthamo - yindlela wokwabelana mbutho, oko kukuthi, igalelo kunye neziphumo ze data kwizixhobo kunye neekhompyutha nabafundi becomputing. Le buffer isetyenziswa njengendawo yokugcina okwethutyana data. Ebudeni benye isixhobo sokufaka iinkcukacha ukujikelezisa data Ngokushicilela kungena luphela, ngoxa abanye ukuvelisa data Funda ixeshana. Xa Ukuveliswa yonke malungana ngqo.

Apho zidibana kumthamo?

Phantse zonke iinkqubo kwi PC oxhulumene nale nkqubo. Umntu lutho akukho lula ukuqonda ukuba yintoni na kumthamo. Noko ke, kulula ukubona: i Ukopisho movie efanayo intanethi - idatha yemphahla, umboniso ulayishiwe kulo cache, kunye nomdlalo, nangona kwi computer yakho okanye hayi.

Lo msebenzi ivumela iinkqubo ukuba enze igalelo data kunye output ngokuzimeleyo. Ngenxa kule luncedo kwayo, kumthamo isetyenziswa multi-OS.

Ezininzi kweentlobo kuyo zisetyenziselwa kwi computer ukuba igalelo, imveliso, kunye processing image. ukuphunyezwa hardware okanye software zenzeka.

Umzekelo kumthamo kwi hardware i modem memory yentsebenziswano, esetyenziswa ukugcina okwethutyana yokuthumela nokufumana iifayili.
Umzekelo kumthamo kwi software yindlela yokusebenza ezininzi, apho yoshicilelo lweenkcukacha i iifayile download yethutyana kwi ncoko efolisiweyo.

abasebenzisi ikhompyutha phambili kufuneka wazi ukuba kumthamo ezinjalo.
Xa kwizifundo zobuxhakaxhaka bolwazi kukho kusoloko kukho umgangatho kwaye olunzulu ulwazi. Wayeqonda ukuba kumthamo ezinjalo, ungaya phambili kwaye ingqalelo ngakumbi lwengcombolo iintlobo zayo.

Yinto eyaziwayo ukuba kukho kumthamo kabini kathathu. Phezu kwabo kuya kuxutyushwa isihlokwana elilandelayo.

Komthamo kathathu - ntoni na?

Xa computer, olu hlobo nkqubo kuxoxwa iintlobo kumthamo kabini. Umahluko kuphela kukuba le ndlela imifanekiso ukubonisa. UmGangatho uphambuke ezintethweni okanye ukunciphisa inani zakudala. Kwakhona, umahluko phakathi kumthamo kabini kathathu iqatshelwe isantya imveliso lo mfanekiso.

indlela kumthamo Triple kwaye ingqanyaniswe a sihlaziya umyinge. Le buffer wesithathu isetyenziswa apha njenge ndlela yokubonelela isithuba izicelo utshintsho ngumthamo opheleleyo yemizobo kwimveliso. Kusebenza uhlobo kwingqwebo. indlela kumthamo triple kufuna izinto ezininzi, kodwa inikeza efanayo rate isakhelo.

Three buffer - ayithethi ukukhawula inani. Nakuba kunjalo, imfuno kwiindawo-4 okanye ngaphezulu kugcino lwefayile ezilayishwe okwethutyana kuba zange ukusebenza iya kusoloko-3 kuphela kubo. Ngoko ke, le ndlela ilungileyo - kumthamo kathathu.

Khawuve oko kumthamo kule midlalo?

Ukuze ukudlulisela imifanekiso imidlalo nayo isebenzisa kumthamo. Le midlalo esetyenziswa njenge kabini, kwaye kathathu. kumthamo kabini asetyenziselwa iiPC isiphelo ophantsi kunye neenkqubo zokusebenza, lo gama i-triple - onama ngakumbi.

Ukuba usebenzisa kumthamo kathathu kwi OS babuthathaka, umdlalo lungangaphumeleli. Ngamanye amazwi, yintoni uhlobo inkqubo lisetyenziswa kwi khomputha yakho ixhomekeke yokusebenza. Imidlalo, kakhulu, yahlukile, kunye neemfuno ezahlukeneyo PC kanye OS.

Khetha uhlobo buffer kuba kunokuba nzima, njengoko abenzi umdlalo ukudala inzala yabo, usebenzisa iindlela ezahlukeneyo zokuhlola. Ngoko ke, umntu udla ukuva kwi zomdlalo amaqonga malunga nendlela umdlalo ethile ayisebenzi kunye kumthamo emithathu, yaye vice versa.

Ngokusesikweni, abenzi kufuneka zibonise iimfuno ezithile inkqubo umdlalo, ukuhambelana kwayo iinkqubo ezahlukeneyo yokusebenza, inkxaso kumthamo, njalo-njalo. D.

Ukuba umenzi akuthethi ukunika ulwazi oluthile malunga ehambelanayo, sinako ukukhangela yena. Kuyo nayiphi na imeko, bachitha kuphela ixesha, ikhompyutha akukho ngozi abusayi. Ukungavumelani zingabonakala phantse nangoko, njengokuba kubhaliwe ibonakaliswa phaya nokuthelekelela lomzobo elekhtrons nemifanekiso amahlwempu enesandi ungqamaniso.

Malunga output kumthamo

Isiphumo komthamo - kakhulu into luncedo. Lo msebenzi ke ingqokelela yazo zonke imveliso yegama elishicilelwe phantsi, fakela cookie kwi header kunye nezinye ezivela kumsebenzi kwesikripthi ethile. Emva kokugqitywa kwezindlela, yonke idatha ethunyelwe umxhasi ngendlela reverse, okt iiheader kuqala, kwandula ke iphepha uze isiphumo ukunikwa iphepha leempendulo alihlole.

Amathuba eziqhutywayo output kumthamo

1. Ukwenza cookie ukusuka ngokupheleleyo naphi leempendulo.
2. Ukuqala iseshoni ngalo naliphi na ixesha.
3. Ngokuveza data phambi kokuba idluliselwe client.

Kufuneka kukhunjulwe ukuba ucinezelo kufuna izibonelelo CPU olongezelelweyo. Kodwa ukudluliselwa ngesantya ziya kwanda ukuya ku-40% (kuxhomekeka kwinani imifanekiso nokubhaliweyo). Yinto eyaziwayo ukuba umfanekiso zixinaniswe umbhalo ngaphantsi kakhulu. Le kumthamo output olungagqibekanga ayinikiwe.

Kukho iindlela 2 ukwenzela imveliso kumthamo:

1. Ifanele ukuba nabani na ongumnini iseva ngokwayo, okanye abanako ukufikelela kwi fayile php.ini. Yonke into efunekayo ufumaneka kule fayile output_buffering myalelo kwaye inike ixabiso On.
2. Indlela yesibini kukuba ukusebenzisa ob_start () kwigama elishicilelwe phantsi, imveliso ye ekufuneka yemphahla.

Apha ukumelana nento yokuba kumthamo ezinjalo.
