Yiziphi izinhlobo zokuxhumana phakathi kwenqubo?
Isahluko sesi-7 Ukuxhumana Okusebenzisanayo
- Amapayipi: imigqa yedatha engaziwa.
- Amapayipi aqanjwe igama: imigqa yedatha enamagama amafayela.
- Ulayini womlayezo wesistimu V, ama-semaphores, nenkumbulo eyabiwe.
- Ulayini wemilayezo ye-POSIX, ama-semaphores, nenkumbulo eyabiwe.
- Izimpawu: iziphazamiso ezikhiqizwe yisoftware.
- Amasokhethi.
- Imemori namafayela afakwe kumephu (bona "I-Memory Management Interfaces")
Iyini i-IPC nezinhlobo zayo ku-Linux?
I-Linux isekela izinhlobo ezintathu zezindlela zokuxhumana ze-interprocess ezivele kuqala ku-Unix TM System V (1983). Lawa olayini bemiyalezo, ama-semaphores kanye nenkumbulo eyabiwe. Lezi zindlela ze-System V IPC zonke zabelana ngezindlela zokufakazela ubuqiniso ezivamile.
Isetshenziswa kanjani i-FIFO ku-IPC?
Umehluko omkhulu wukuthi i-FIFO inegama ngaphakathi kwesistimu yefayela futhi ivulwa ngendlela efanayo nefayela elivamile. Lokhu kuvumela i-FIFO ukuthi isetshenziselwe ukuxhumana phakathi kwezinqubo ezingahlobene. I-FIFO inesiphetho sokubhala nesiphetho esifundwayo, futhi idatha ifundwa epayipini ngendlela efanayo ebhalwe ngayo.
Yiziphi izindlela ezi-3 ze-IPC?
Lezi izindlela ku-IPC:
- Amapayipi (Inqubo efanayo) - Lokhu kuvumela ukugeleza kwedatha ohlangothini olulodwa kuphela. …
- Amapayipi Amagama (Izinqubo Ezihlukene) - Leli ipayipi elinegama elithile elingasetshenziswa ezinqubweni ezingenayo imvelaphi yenqubo evamile okwabelwana ngayo. …
- Ukufakwa Emugqeni Umlayezo - ...
- Ama-Semaphores -…
- Inkumbulo eyabiwe - ...

Yiziphi izinhlobo ezimbili ze-IPC?
Kunamamodeli amabili ayinhloko okuxhumana okusebenzisanayo: inkumbulo eyabiwe kanye. ukudlula umlayezo.
Ayini amamodeli amabili e-IPC Ayini amandla nobuthakathaka bezindlela ezimbili?
Amandla:1. Ukuxhumana ngenkumbulo okwabiwe kushesha imodeli yokudlula umlayezo uma izinqubo zikumshini ofanayo. Ubuthakathaka:1. … Izinqubo ezixhumana kusetshenziswa inkumbulo eyabiwe zidinga ukubhekana nezinkinga zokuvikela inkumbulo nokuvumelanisa.
Kuyini ukuxhumana kwe-interprocess Sanfoundry?
Incazelo: I-Interprocess Communication (IPC) iyindlela yokuxhumana evumela izinqubo ukuthi zixhumane futhi zivumelanise izenzo zazo ngaphandle kokusebenzisa indawo yekheli efanayo.
Kungani i-Semaphore isetshenziswa ku-OS?
Ama-Semaphore ayizinombolo eziguquguqukayo ezisetshenziselwa ukuxazulula inkinga yesigaba esibalulekile ngokusebenzisa imisebenzi emibili ye-athomu, ukulinda kanye nesignali esetshenziselwa ukuvumelanisa inqubo. Umsebenzi wokulinda wehlisa inani le-agumenti yawo ethi S, uma ithi phozithivu. Uma u-S ethi unegethivu noma uziro, akukho msebenzi owenziwayo.
Uyini umjikelezo wempilo yenqubo?
Izigaba inqubo yomzimba noma uhlelo lokuphatha oludlula kuzo njengoba luqhubeka kusukela ekuzalweni kuya ekufeni.
Uyini umsebenzi we-kernel?
I-kernel yenza imisebenzi yayo, efana nezinqubo ezisebenzayo, ukuphatha amadivaysi ehadiwe njenge-hard disk, nokuphazamiseka kokubamba, kulesi sikhala se-kernel esivikelwe. Ngokuphambene, izinhlelo zohlelo lokusebenza njengeziphequluli, izicubunguli zamagama, noma izidlali zomsindo noma zevidiyo zisebenzisa indawo ehlukile yenkumbulo, isikhala somsebenzisi.
