Mathoasong a mahlale a k'homphieutha, e 'ngoe ea mathata a mantlha a mosebelisi e ne e le ho se sebetsane hantle ha lisebelisoa - li-ports tse ngata tsa heterogenible li ne li ikarabella bakeng sa ho hokahanya likarolo tse ngata, tseo boholo ba tsona e neng e le tse ngata ebile li tšepahala ka tlase. Tharollo e ne e le "bese ea serial" kapa, ka bokhutšoanyane, USB. Ka lekhetlo la pele, koung ena e ncha e ile ea hlahisoa sechabeng ka kakaretso ka 1996. Ka 2001, li-board tsa bo-mme le lisebelisoa tsa USB tsa kantle li ile tsa fumaneha ho bareki, mme ka 2010 USB 3.0 e ile ea hlaha. Joale ho na le phapano efe lipakeng tsa mahlale aa le hore na ke hobane li hlokahala ka bobeli?
Phapang lipakeng tsa USB 2.0 le 3.0
Pele ho tsohle, hoa bohlokoa ho hlokomela hore likou tsohle tsa USB lia lumellana. Sena se bolela hore ho hokahanya sesebelisoa se liehang boemakepeng bo potlakileng le ho fapana hoa khoneha, empa sekhahla sa phapanyetsano ea data se tla ba se fokolang.
O ka "supa" maemo a sehokelo ka pono - ka USB 2.0 bokaholimo ba ntlo bo pentiloe tšoeu, 'me ka USB 3.0 - putsoa.

Ntle le moo, likhoele tse ncha ha li na mehala e mene, empa li na le lithapo tse robeli, tse etsang hore li be matla li be li fetohe habonolo. Ka lehlakoreng le leng, sena se eketsa ts'ebetso ea lisebelisoa, li ntlafatsa likarolo tsa phetiso ea data, 'me ka lehlakoreng le leng, e eketsa litšenyehelo tsa thapo. E le molao, likhoele tsa USB 2.0 li bolelele ba makhetlo a 1.5-2 ho feta baena ba bona "ba potlakileng". Ho na le phapang ka boholo le tlhophiso ea mefuta e tšoanang ea lihokela. Kahoo, USB 2.0 e arotsoe ka:
- mofuta A (o tloaelehileng) - 4 × 12 mm;
- mofuta oa B (o tloaelehileng) - 7 × 8 mm;
- mofuta oa A (Mini) - 3 × 7 mm, trapezoidal e nang le likhutlo tse pota-potiloeng;
- mofuta oa B (Mini) - 3 × 7 mm, trapezoidal e nang le li-angles tse nepahetseng;
- mofuta oa A (Micro) - 2 × 7 mm, likhetla;
- mofuta B (Micro) - 2 × 7 limilimithara, tse halofo ka likhutlo tse chitja.
Lithapelong tsa khomphutha, mofuta o tloaelehileng oa USB A o sebelisoa hangata ho lisebelisoa tsa thekeng - Type B Mini le Micro. Sehlopha sa USB 3.0 se boetse se rarahane:
- mofuta A (o tloaelehileng) - 4 × 12 mm;
- mofuta oa B (o tloaelehileng) - 7 × 10 mm, sebopeho se rarahaneng;
- mofuta oa B (Mini) - 3 × 7 mm, trapezoidal e nang le li-angles tse nepahetseng;
- mofuta B (Micro) - 2 × 12 limilimithara, tse halokiloeng ka likhutlo tse pota-potiloeng le phomolo;
- mofuta oa C - 2,5 × 8 mm, e nang le likonopo tse pota-potiloeng.
Mofuta oa A o ntse o fumaneha ka har'a lik'homphieutha, empa mofuta oa C o ntse o tsebahala haholo letsatsi le leng le le leng. Adapter ea litekanyetso tsena e bontšoa setšoantšong.
