Nhazi ọkwa nke na kọmputa na netwọk

Ozugbo mmadụ e kere kọmputa, ọ chọrọ ka e kere eke nke a ọhụrụ obibia nke nzukọ nke usoro, data nhazi, nakwa dị ka ihe e kere eke nke nkà na ụzụ ọhụrụ na ubi nke nchekwa, nyefe na ojiji nke ozi. Mgbe oge ụfọdụ gasịrị, e nwere mkpa ime site na onye kọmputa, sistem, data nhazi na-centralized na usoro ike nhazi data nkesa.

Ekesa data nhazi aha ndị dị otú ahụ ozi nhazi na a rụrụ onwe ha ma interconnected kọmputa gụnyere ekesa usoro.

The kọmputa netwọk bụ a collection of kọmputa na na-interconnected site nkwurịta okwu njikọ, nke na-enye ohere ka ike otu usoro na n'ụzọ zuru ezu igbo chọrọ nke na-ekesa ozi nhazi iwu. N'ihi ya, isi nzube nke na kọmputa na netwọk - a nkwonkwo data nhazi, nke na-eweta ọnụ niile mmiri nke usoro, n'agbanyeghị nke ahụ ha na ọnọdụ.
