Kuzinhlelo zokusebenza zekhompuyutha ezifana ne-Unix, ipayipi liyindlela yokuxhumana phakathi kwezinqubo kusetshenziswa ukudlulisa umyalezo. Iphayiphi isethi yezinqubo ezihlanganiswe ndawonye ngokusakaza kwazo okujwayelekile, ukuze umbhalo ophumayo wenqubo ngayinye (stdout) udluliselwe ngokuqondile njengokungenayo (stdin) ukuya kwelandelayo.
Ipayipi isebenza kanjani ku-Linux?
Ku-Linux, umyalo wepayipi ikuvumela ukuthi uthumele okukhiphayo komyalo owodwa komunye. Ipayipi, njengoba igama liphakamisa, lingaqondisa kabusha okukhiphayo okujwayelekile, okokufaka, noma iphutha lenqubo eyodwa iye kwenye ukuze kuqhutshekwe nokucubungula.
Lisebenza kanjani igobolondo lamapayipi?
Ipayipi ixhuma okukhiphayo okujwayelekile kwenqubo kwesokunxele kokokufaka okujwayelekile kwenqubo yakwesokudla. Ungakucabanga njengohlelo oluzinikele olunakekela ukukopisha yonke into ephrintwa wuhlelo olulodwa, bese uluphakela ohlelweni olulandelayo (olulandela uphawu lwepayipi).
Ngabe ukusebenza kwepayipi kusebenza kanjani?
Umsebenzi wepayipi ithatha uchungechunge lwemisebenzi engu-n; lapho ukusebenza ngakunye kuthatha ingxabano; icubungule; futhi inikeze okukhiphayo okucutshunguliwe njengokufakwayo komsebenzi olandelayo ngokulandelana. Umphumela womsebenzi wepayipi uwumsebenzi oyinguqulo ehlanganisiwe yokulandelana kwemisebenzi.
Yini ebizwa ngokuthi ipayipi ku-Linux?
I-FIFO, eyaziwa nangokuthi ipayipi eliqanjwe igama, i ifayela elikhethekile elifana nepayipi kodwa elinegama ohlelweni lwefayela. Izinqubo eziningi zingafinyelela leli fayela elikhethekile lokufunda nokubhala njenganoma yiliphi ifayela elijwayelekile. Ngakho, igama lisebenza kuphela njengendawo eyinkomba yezinqubo ezidinga ukusebenzisa igama ohlelweni lwefayela.
Ipayipi liyenza kanjani imali?
Ipayipi yenza imali engenayo ephindelelayo edayiswa ngevelu yakhona yonyaka, okusho ukuhamba kwemali okwengeziwe ezinkampanini ezikalayo. Azikho izaphulelo, akukho sikweletu, akukho dilution.
Mingaki imiyalo ongayihlanganisa ngesikhathi esisodwa?
2 Izimpendulo. Ngolwazi ezinalo, akukho mkhawulo enanini lamapayipi, njengoba imiyalo imane ikhishwe ngokulandelana. Okuwukuphela komkhawulo kuzoba inani ledatha elidluliswa ngepayipi, noma "Umkhawulo Wesivikelo Sepayipi."
Uyini umkhawulo wepayipi?
Umkhawulo wamapayipi wokuxhumana kwe-interprocess ngu ukuthi izinqubo ezisebenzisa amapayipi kumele zibe nenqubo yomzali efanayo (okungukuthi, yabelana ngenqubo evamile yokuvula noma yokuqalisa futhi ibe khona njengomphumela wekholi yesistimu yemfoloko evela kwinqubo yomzali). Ipayipi lilinganiselwe ngosayizi futhi ngokuvamile okungenani lingamabhayithi angu-4,096.
Yiziphi izici ze-Unix?
Uhlelo lokusebenza lwe-UNIX lusekela izici namakhono alandelayo:
- Ukwenza izinto eziningi kanye nabasebenzisi abaningi.
- Isixhumi esibonakalayo sokuhlela.
- Ukusetshenziswa kwamafayela njengezifinyezo zamadivayisi nezinye izinto.
- Inethiwekhi eyakhelwe ngaphakathi (i-TCP/IP ijwayelekile)
- Izinqubo zesevisi yesistimu eqhubekayo ebizwa ngokuthi “ama-daemons” futhi ilawulwa yi-init noma i-inet.
Iyini inhloso ku-Unix?
I-Unix iyisistimu yokusebenza. It isekela ukwenza izinto eziningi nokusebenza kwabasebenzisi abaningi. I-Unix isetshenziswa kakhulu kuzo zonke izinhlobo zezinhlelo zekhompiyutha ezifana nedeskithophu, ilaptop, namaseva. Ku-Unix, kune-Graphical interface yomsebenzisi efana namawindi asekela ukuzulazula okulula nendawo esekelayo.
Liyini ipayipi kuhlelo lwe-C?
Ipayipi ikholi yesistimu edala isixhumanisi sokuxhumana esingaqondile phakathi kwezichazi zefayela ezimbili. Ucingo lwesistimu yamapayipi lubizwa ngesikhombi ohlwini lwamanani aphelele amabili. … Ingxenye yesibili yohlelo iqukethe isichazi sefayela esihambisana nokufaka ipayipi (indawo obhala kuyo izinto).
Uyini opharetha wepayipi nge-angular?
Ungasebenzisa amapayipi ukuxhumanisa opharetha ndawonye. Amapayipi akuvumela hlanganisa imisebenzi eminingi ibe umsebenzi owodwa. Umsebenzi wepayipi() uthatha njengama-agumenti awo imisebenzi ofuna ukuyihlanganisa, futhi ibuyisela umsebenzi omusha othi, lapho wenziwe, uqhube imisebenzi ehlanganisiwe ngokulandelana.
