Data Nchekwa: ngwaọrụ na iji

A data nkwakọba bụ a usoro na-echekwa nnukwu ichekwa ihe ọmụma. Ọ na-agụnye ndị dị otú ahụ mmiri dị ka standalone software (dịrị gaba n'ime ebe - Software), nchekwa media (draịva), nakwa dị ka ụzọ nke nkwurịta okwu. All nke a bụ na a iche iche ngọngọ.

Network Nchekwa data bụ ihe akụkụ nke a n'ụlọ ma ọ bụ ụlọ ọrụ na netwọk, iji nye na-aga n'ihu na ịnweta ozi nke a onye ma ọ bụ azụmahịa na okike.

Tụlee ihe zuru ezu na mmiri na nkejikotara ọ bụla data store. Independent software ahazi ndekọ, nchekwa na nnyefe nke ozi. Ọ dabeere na:
- Esịtidem Them sistemụ;
- mgbochi nje software;
- software na-enye data mgbanwe;
- software maka nzukọ n'ihi na wakporo-arrays, iji nwekwuo ntụkwasị obi nke usoro;
- Ndị ọzọ ọrụ software.

N'aka ọmụma e chekwara ihe ole na ole ibu diski (na-emekarị 3-5 PC.), Enịm ke otu ngọngọ. N'ihi na sistemụ arụmọrụ (dịrị gaba n'ime ebe - OS) nchekwa adịghị ekwe ka ihe e kere eke nke ezi uche dị na draịva, ie OS arụnyere na a ike disk, deletes ya si ndepụta draịva eji na flash kaadị ma ọ bụ ndị ọzọ siri ike-ala mbanye (a na-akpọ SSD-mbanye) ka bootable media.
nkwurịta okwu n'aka iji chọpụta usoro nke ndị data store ga-ekwurịta okwu na onye ọrụ. Ekwe Omume embodiments nke ogige a pụtara:
- Wired njikọ iji TCP / IP protocol. Na nke a, esịtidem processor ejiri file arịrịọ ka larịị nke sistemụ iwu Them. Hapụ ọrụ anya bụ 10 km.
- A njikọ ikuku na-wuru na ọkọlọtọ Wi-Fi technology, na nwere a mmachi ike transceivers, nakwa dị ka bufee nchedo ụlọ ọrụ.
Networked nchekwa nwere fọrọ nke nta na-akparaghị ókè nso nke ngwa: si nchekwa nke multimedia faịlụ kpokọta ozi na CCTV ese foto. Ndị isi uru idu ke eziokwu na ihe ọmụma odụk data nkwakọba, na-ezere omenala processors. Nke a na-ekwe omume site na esịtidem processor, nke Filiks na ọ na.
N'ihi ya, data ụlọ ahịa nwere ọtụtụ uru, isi n'etiti nke bụ ekwe omume nke na-ebutu ngwaike ike nke onye ọrụ kọmputa nke na-eme arụmọrụ, dị ka ide na-agụ nke nnukwu ichekwa ihe ọmụma, arụmọrụ management na ịchịkwa network arụmọrụ ke Internet ma ọ bụ obodo ebe netwọk, ndekọ ma playback multimedia faịlụ.
Ọ bụkwa uru arịba ama na n'ihi na eziokwu na nke ugbu a usoro e mepụtara elu-ọsọ data nnyefe na uwa na netwọk, ma e nwekwara nchekwa nke nnukwu mpịakọta nke ozi, wee malite ịpụta pụrụ iche nchekwa - file mba.
