Ubushishozi

Niba ikarita yawe ya SIM ifunze kubera kwinjiza PIN itari yo inshuro nyinshi, uzakenera PUK (Urufunguzo rwo guhagarika umuntu). Iyi kode isanzwe iboneka kumpapuro yumwimerere ya SIM ikarita cyangwa itangwa na terefone yawe igendanwa.

Nomero ya simukadi, izwi kandi nka ICCID (Integrated Circuit Card Identifier), ni indangamuntu idasanzwe ifitanye isano na simukadi yawe kandi ikora nk'intoki ya digitale kuri neti yawe igendanwa. Mubisanzwe numubare 19 kugeza kuri 20 wacapishijwe kuri SIM karita cyangwa ugaragara mumiterere ya terefone.

Mudasobwa yakira inganda, igikoresho gifata umwanya wibanze murwego rwo gutangiza inganda, bifite byinshi bisa na mudasobwa zacu bwite, ariko hariho itandukaniro rigaragara. Byombi ni mudasobwa, ariko porogaramu ikoreshwa, ibitekerezo byo gushushanya n'intego zo gukoresha biratandukanye cyane. None, inganda zakira inganda zishobora gukoreshwa nka mudasobwa?

Hamwe niterambere ryihuse ryimikorere yinganda, imikorere nubwizerwe bwa mudasobwa zinganda biragenda biba ibintu bikomeye. Ibicuruzwa bya mudasobwa yinganda zishyigikira ububiko bwa DDR5 nabwo buzana impinduramatwara mubikorwa byo kugenzura inganda.

Muri iyi si ya none, kumenya ibijyanye no kubika amakuru ni ngombwa. RAID (Arundant Array ya Disiki Yigenga) nuguhitamo kwambere kubika amakuru neza. RAID 5 na RAID 6 nubwoko bubiri bwingenzi butanga inzira zitandukanye zo kurinda amakuru yawe.

Kwagura ibyambu byububiko bwa mudasobwa yububiko bwashyizwemo ni bike cyane ugereranije nizindi mudasobwa nini zinganda; mudasobwa yashyizwemo inganda irasabwa cyane cyane kubakiriya bafite ibisabwa mubunini bwimashini, kuko ni nto kandi yoroshye, gukoresha ingufu nke, hamwe nubushyuhe bwagutse, nabwo bukaba inyungu zidasanzwe ziki gicuruzwa.

RAID (Redundant Array ya Disiki Yigenga) ihuza disiki nyinshi mubice bimwe. Itezimbere umutekano wamakuru, umuvuduko, no kwiringirwa. Guhitamo hagati ya software hamwe nibyuma RAID ningirakamaro mukubika amakuru yawe no kuzamura imikorere.

Sisitemu yerekana imyanya ni porogaramu yingenzi itahura imyanya nogukoresha binyuze muburyo bwa tekinoroji ya mudasobwa, itanga ibisubizo byikora byikora kumurongo wibyakozwe byikora, gusesengura amashusho kure, gusesengura amashusho yubuvuzi, kugenzura umutekano no gukurikirana, nibindi bice.

Muri iki gihe cyihuta cyane, abanyamwuga bagomba kumva ibyambu bya SFP. Icyambu cya SFP gitanga uburyo butandukanye bwo guhuza kubintu bitandukanye. Ifasha fibre optique hamwe ninsinga z'umuringa. Ibi biroroshe gushiraho imiyoboro ishingiye kumuvuduko nintera isabwa.
