3. Irdy # (uwatangije yiteguye):
Yerekana ko igikoresho cya Databuja cyiteguye kohereza amakuru. Mugihe cyamasaha yo kwimura amakuru, niba shebuja ashobora gutwara amakuru kuri bisi, yemeza irdy #.
4. Tvsel # (Igikoresho Hitamo):

Ibindi bimenyetso

Shyiramo ibimenyetso bikoreshwa mukemuragura Bus, kugenzura igenamigambi ryiza rya bisi mubikoresho byinshi bisaba kwinjira icyarimwe.
Ibimenyetso byo guhagarika (Inta #, intb #, intc #, intd #):
Byakoreshejwe nibikoresho byabacakara kugirango wohereze ibyifuzo byo guhagarika uwakiriye, ubimenyeshe ibintu byihariye cyangwa impinduka za leta.
Muri make, ibisobanuro bya PCI byerekana ibimenyetso bifatika byerekana imirongo yikimenyetso ishinzwe kwimura amakuru, kugenzura ibikoresho, gutanga amakuru, no guhagarika amakosa, no guhagarika gufatana kuri bisi ya PCI.
