Kuyini kokubhafa: imininingwane

Ukugcina kumthamo - iyindlela ukwabelana inhlangano, + okuwukuthi, input bese okukhipha idatha ku Computing amadivayisi namakhompyutha. Sesikhashana isetshenziswa njengendawo yokugcina ukwaziswa okwesikhashana. Phakathi kudivayisi eyodwa idatha okokufaka ukukhiqiza idatha ukurekhoda ku sesikhashana, kuyilapho abanye ukukhiqiza idatha wokufundwayo kusukela sesikhashana. Esikhathini ongaziwa umsuka walo we zonke okuphambene ngqo.

Lapho sihlangana kokubhafa?

Cishe zonke izinqubo e PC axhunyiwe nale nqubo. umuntu lutho akulula ukuqonda ukuthi yini nokulinda. Nokho, kulula ukuba sithi: elifanayo okulandwayo movie ku-intanethi - idatha buffered, ifilimu selulayisheke ku isilondolozi, nokudlala, nakuba kwikhompyutha yakho noma cha.

Lo msebenzi ivumela izinqubo ukwenza idatha input bese okukhipha ngokuzimela. Ngenxa yalesi angasetshenziswa, kokubhafa isetshenziswa multi-OS.

Eziningana zezinto eziphilayo yayo asetshenziswa eseyi okufakwayo, okukhipha, futhi processing image. ukuqaliswa yabo hardware noma isofthiwe zenzeka.

Isibonelo kokubhafa kule hardware kuyinto imodemu inkumbulo op, esetshenziselwa ukugcina okwesikhashana ukuthumela amafayela.
Isibonelo kokubhafa e isofthiwe kuyinto system yokusebenza eziningi, lapho kufakwa ukuphrinta kuyinto yesikhashana thwebula amafayela kulayini ukuphrinta.

Advanced abasebenzisi computer kufanele uqaphele ukuthi kokubhafa ezinjalo.
Esikhathini emkhakheni kolwazi nobuchwepheshe siyohlale ebusweni kanye ngokujulile ulwazi. Ukuqonda ukuthi kokubhafa ezinjalo, ungaya phambili nokucabangela eningiliziwe zinhlobo ayo.

Kuyaziwa ukuthi kukhona kokubhafa double futhi kathathu ezaziwayo. On kubo kuzoxoxwa ngakho isihlokwana esilandelayo.

Ukugcina kumthamo Kathathu - kuyini?

Ngo eseyi, lolu hlobo inqubo kuxoxwa ezihlukahlukene kokubhafa double. Umahluko owokuthi indlela yokubonisa izithombe. Kathathu ukugwema noma ukunciphisa inani zobuciko. Futhi, umehluko phakathi kokubhafa double futhi kathathu ebonwe ijubane okukhipha yesithombe.

Kathathu kokubhafa indlela futhi ivumelanisiwe ne ngesilinganiso vuselela. Sesikhashana lwesithathu lisetshenziswa lapha njengendawo indlela yokunikeza isikhala ushintsho izicelo umthamo isamba okukhipha ihluzo. Kusebenza njengomnyombo uhlobo esitolo. kathathu kokubhafa indlela kudinga izinsiza, kodwa inikeza uhambisane lozimele.

Three sesikhashana - awusebenzi zinciphise isibalo. Nokho, isidingo 4 noma ngaphezulu ezindaweni isitoreji okwesikhashana amafayela alayishiwe akuyona kusebenta ngekukhutsala luyohlale 3 wabo kuphela. Ngakho-ke, ukhetho best - kokubhafa kathathu.

Cabanga ngalokho kokubhafa emidlalweni?

Ukuze uthumele izithombe imidlalo futhi isebenzisa nokulinda. Imidlalo lisetshenziswa njengedivaysi double, futhi kathathu. kokubhafa Double isetshenziselwa a PC ephansi ekupheleni kanye namasistimu asebenzayo, kuyilapho kathathu - I-namandla kakhulu.

Uma usebenzisa kokubhafa kathathu ku-OS ababuthakathaka, umdlalo ongahlabeki. Ngamanye amazwi, uhlobo olunjani inqubo esetshenziswa kukhompyutha yakho kuncike ukusebenza. Imidlalo, futhi, zihlukile, nezimfuneko ezahlukene i-PC ye-OS.

Khetha uhlobo sesikhashana kunalokho nzima, njengoba abenzi umdlalo ukudala nenzalo yabo, usebenzisa izindlela ezahlukene zokuhlola. Ngakho-ke, umuntu angabona ngokuvamile ukuzwa ku kugembula izinkundla mayelana nendlela umdlalo othile akusebenzi ne kokubhafa kathathu, futhi okuphambene nalokho.

Kahle kahle, abakhiqizi kumele ukhombise nezimfuneko ezithile simiso umdlalo, ukuhambisana yayo ne yokusebenza izinhlelo ezahlukene, kokubhafa ukwesekwa, nokunye. D.

Uma umenzi akukuniki ulwazi oluthile mayelana ukuhambisana, kungenzeka ukuba uhlole yena. Kunoma ikuphi, wachitha kuphela isikhathi, i-computer akulimazi ngeke nilingenise. Ukungavumelani kungabonwa cishe ngokushesha, njengoba eyaziwako braking ngeso sokuqhafaza nemifanekiso abampofu umsindo ukuvumelanisa.

Mayelana okukhipha kokubhafa

Lokukhipha Ukugcina kumthamo - ngempela kuyinto ebalulekile. Lokhu kusebenza le ukustaka yazo zonke ekhishwa zombhalo, yengeze ikhukhi kuya unhlokweni kanye nezinye okubangelwa umsebenzi iskripthi ethile. Ngemva kokuphothulwa ukucutshungulwa kolwazi, yonke idatha uthunyelwa amaklayenti e-oda reverse, ie izihloko kuqala, bese ikhasi bese umphumela iskripthi.

Amathuba ahlinzekwa ngokusebenzisa okukhipha kokubhafa

1. Ukwenza amakhukhi ngokuphelele kuphi iskripthi.
2. Ukuqala kuseshini nganoma yisiphi isikhathi.
3. Iyanciphisa idatha ngaphambi bakuthumela iklayenti.

Kufanele kukhunjulwe ukuthi kokucindezelwa kuzodinga ezengeziwe CPU imithombo. Kodwa ukudluliselwa ngesivinini kuzokhulisa ukuba 40% (kuye ngokuthi isibalo izithombe nombhalo). Kuyaziwa ukuthi isithombe onomfutho umbhalo ingasaphathwa. I kokubhafa okuzenzakalelayo okukhipha ayivunyelwe.

Kukhona 2 izindlela ukunika amandla okukhipha kokubhafa:

1. Ifanele umuntu ongumnikazi iseva uqobo, noma abafinyelela ifayela php.ini. Konke kuyadingeka itholakala kuleli fayela output_buffering siqondiso futhi ukwabela Inani Vuliwe.
2. Eyesibili indlela ukusebenzisa ob_start () e zombhalo, ekhishwa okumele buffered.

Lapha esibhekana ngayo yokuthi kokubhafa ezinjalo.
