Chii chinonzi CAP theorem mu computer science?
Context:Mune theoretical computer science, CAP theorem, inonziwo Brewer's theorem mushure memusayendisiti wemucomputer Eric Brewer, inoti chero dhata rekuchengetera rakagoverwa rinogona kupa zviviri chete zvezvinhu zvitatu zvinotevera:  Kuwirirana Kuverenga kwose kunogamuchira kunyorwa kwazvino uno kana kuti mhosho. Kuwanika Chikumbiro chimwe nechimwe chinogamuchira mhinduro (isina kukanganisa), pasina vimbiso yokuti ine kunyorwa kwazvino. Kuparadzanisa kushivirira Sangano rinopfuurira kushanda pasinei nenhamba isingazivikanwi yemashoko ari kudonhedzwa (kana kunonoka) nehutano pakati pemakona. Apo kukundikana kwechikamu chekugoverana kunoitika, kunofanira kusarudzwa kana kuita chimwe chezvinhu zvinotevera:  kudzima oparesheni uye nokudaro kuderedza kuwanika asi nechokwadi kusachinja-chinja kupfuurira nebasa racho uye nokudaro kupa kuwanika asi pangozi kusawirirana.  Nokudaro, kana pane parutivi rwenetwork, mumwe anofanira kusarudza pakati pokusachinja-chinja kana kuti kuwanika. Cherechedza kuti kusachinja-chinja sezvinorondedzerwa muCAP theorem kwakasiyana zvikuru nekusachinja-chinja kunovimbiswa mu ACID dhatabhesi yekutengesa.  Eric Brewer anoti kazhinji kushandiswa "vaviri vatatu" pfungwa kunogona kuva zvishoma zvinotsausa nokuti hurongwa vagadziri chete vanofanira kubayira kusachinja-chinja kana Kuwanikwa pamberi partitions, asi kuti vakawanda hurongwa partitions vari vashoma.
CAP theorem, inonziwo Brewer's theorem, inoti nzvimbo dzinochengetwa mashoko dzinogona kupa zvivimbiso zviviri chete pazvitatu: kuwirirana, kuwanika, uye kushivirira kwekuparadzanisa. Apo parutivi rwomumbure runokundikana, kunofanira kusarudzwa kana kukanzura kushanda kana kupfuurira nokushanda. Eric Brewer anoti pfungwa yokuti "vaviri pavatatu" inogona kutsausa.
