Kwibhasi yekhompyutheni, ibhasi yedatha- ebizwa ngokuba yi-processor ibhasi, ibhasi elingaphambi kwebhasi, ngaphambili kwebhasi okanye ibhasi elingemuva-liqela leentambo zombane ezisetyenziselwe ukuthumela ulwazi (idatha) phakathi kwezinto ezimbini okanye ngaphezulu. Umqhubi we-Intel kumgca we-Macs okwangoku, umzekelo, usebenzisa ibhasi yedatha engama-64 ukuxhuma umproseshi kwimemori yakhe.
Ibhasi yedata ineziganeko ezininzi ezicacileyo, kodwa enye ebaluleke kakhulu ububanzi bayo. Ububanzi bebhasi yedata bubhekisela kwinani leebitshi (zombane iingcingo) ezenza ibhasi. Ububanzi obubanzi bebhasi yedatha kubandakanya i-1-, 4-, 8-, 16-, 32-, kunye ne-64-bit.
Xa abakhiqizi bebhekisela kwinani leebitshini esebenzisa iprojekthi, efana nale "khompyutheni isebenzisa iprosesa engama-64," ibhekisela kububanzi bebhasi yedatha yangaphambili, ibhasi edibanisa umprosesari kwimemori yayo eyintloko. Ezinye iintlobo zeebhasi zedata ezisetyenziswe kwiikhomputha ziquka ibhasi elingasemva, elidibanisa umprosesa kwimemori yokugcina imemori.
Ibhasi leedatha lilawulwa ngumlawuli webhasi olawula isivinini solwazi phakathi kwezinto. Ngokuqhelekileyo, yonke into idinga ukuhamba ngesantya esifanayo kwikompyutha kwaye akukho nto inokuhamba ngokukhawuleza kuneCPU. Abalawuli bebhasi bagcina izinto zihamba ngesantya esinye.
Ama-Mac asekuqaleni asebenzisa ibhasi yedata ye-16; I-Macintosh yasekuqaleni isebenzisa i-protocol ye-Motorola 68000. Ama-Macs amatsha usebenzisa amabhasi ama-32 okanye ama-64-bit.
Iindidi zeebhasi
Ibhasi leedatha linokusebenza njenge- serial okanye ibhasi efana . Iibhasi ezinjenge- USB kunye ne- FireWire uxhumano-isebenzisa intambo enye kubo bobabini bathumela baze bafumane ulwazi phakathi kwezinto. Ukuxhunywa kweebhasi ezifana ne-SCSI-sebenzisa ezininzi iingcingo ukuxubana phakathi kwezinto. Ezi bhasi zingangaphakathi ngaphakathi kwiprosesor okanye yangaphandle , ngokumalunga necandelo elinikeziweyo elixhunyiwe.
