History of indalo

Imbali, njengoko kwiimeko ezininzi, izixhobo zokugcina data, sele iqalile kunye nokwamkelwa mgangatho omnye. Kwathatha ukuhlanganisa iinzame eziliqela bamaqela ngamaqela likhulu ezazifanele ukuba nje siyavumelana ngale ndawo.

Ngo-1999 laye lamkela Secure Digital eqhelekileyo, kunye neesampuli yokuqala babonelelwa isilawuli yayo kunye nokhuseleko ngoomatshini nxamnye okungagunyaziswanga ukufunda nokubhala nolwazi. ukhuseleko Data ngelo xesha omnye wemiqathango ezisisiseko.

SD standard sizukulwana sokuqala kuvumela ukwenza amakhadi ukuya kwi-2 GB. Ngelo xesha ke imbonakalo umgangatho oko kwakwanele. Inguqulelo zaphuculwa, ezafumana ukwalathelwa SD 1.1, uvunyelwe ukuba ukudala umthamo ukuya ku 4GB. Noko ke, ngokukhawuleza yaba asanelanga, ngoko kwakukho SDHC eqhelekileyo ukuya ku 32GB. Ngubani na inqanaba entsha ngokupheleleyo ngoku - SDXC, elikuvumela ukuba ukudala ikhadi lememori, umthamo yayo ibe terabytes ukuya ku-2.

iimpawu technical

Ngaphandle kwezinye izinto eziqhelekileyo, microSD mihla imemori khadi Oku kwahluke kakhulu kuyo oko kwiminyaka eli-10 eyadlulayo. Ayavumelana yi umgangatho omnye kuphela, yamkelwe njengesiseko.

Ngoku ngokubanzi kusetyenziswa amakhadi SDHC, ezahlukileyo kwezinye iiklasi. Udidi asezantsi - owesibini, inika isantya ukurekhodwa ukuya ku-2 MB / umzuzwana.

ininzi kakhulu into ngake xaka ufomatha ikhadi lememori, nangona oku kuvame efunekayo. Noko ke, ayanda iklasi, kungona isantya ikhadi. Kwezinye iimeko, zithembekile kakhulu, ngoko ke umbuzo kukuba ukubuyisela indlela imemori khadi nje asivelanga. Noko ke, imilinganiselo ezintsha basombulula iingxaki kuphela umthamo kunye nesantya umsebenzi, kodwa ukuthembeka ophethe data esetyenziswa phantse zonke iintlobo izixhobo zale mihla. Kule meko sithetha ngayo ukusebenza kunye abenzi izixhobo kunye nabenzi ikhadi.
