ndazi Owona mahluko uphawuleka kakhulu phakathi kwe-USB 2.0 kunye ne-USB 3.0 kunye nezona mpawu zibalulekileyo.
i i-USB sisishunqulelo se I-Universal Serial Bus. Lujongano olusetyenziswa ukudibanisa iiperipherals ezinje: impuku وikhibhodi وumshicileli وhard drives kwikhompyuter yakho.
ikhutshiwe USB 2.0 ngonyaka 2000 Ziinguqulelo ezininzi ze i-USB esetyenziswayo ukuza kuthi ga ngoku.
ikhutshiwe USB 3.0 ngonyaka 2008 Ngokuthe ngcembe uthatha iintambo.
njengokuba USB 2.0 و USB 3.0 Baneseti eyodwa yeempawu. Ke ngoko, ngeli nqaku, siya kwazi kunye Zonke iiyantlukwano phakathi kwe-USB 2.0 و USB 3.0.
Umahluko phakathi kwe-USB 2.0 kunye ne-USB 3.0
Ngemigca elandelayo, siya kukwazi Umahluko phakathi kwe-USB 2.0 kunye ne-USB 3.0 Ngoko masiqalise.
1. Inkangeleko yomzimba
- Izihlanganisi USB 2.0 emnyama ngaphakathi , Ngelixa USB 3.0 blue ngaphakathi.
- I-USB 2.0 ineengcingo ezi-4 zokudibanisa , Ngelixa I-USB 3.0 ineengcingo ezi-9 zokudibanisa.
Ngenxa yoko, izihlanganisi USB 3.0 mkhulu kunomqhubi USB 2.0. Ngaloo ndlela, ukulungiselela iingcingo ezongezelelweyo.
Kwaye ngoko, Izihlanganisi ze-USB 3.0 azinakusetyenziswa kunye ne-USB 2.0 port.
2. Isantya sokutshintshela
- ukufikelela USB 2.0 isantya sokudlulisa Ngase 480 Mbps.
- ukufikelela USB 3.0 isantya sokudlulisa Ngase 4.8 Gbps.
Ngoko ke I-USB 3.0 ikhawuleza kayi-10 kune-USB 2.0.
3. Ukuhambelana ngasemva
amazibuko USB 3.0 Ngasemva iyahambelana. Ngaloo ndlela, isixhobo sinokudityaniswa USB 2.0 izibuko USB 3.0.
Nangona kunjalo, xa isixhobo sixhunyiwe USB 3.0 izibuko USB 2.0 , izantya zogqithiso lwedatha ziya kulinganiselwa USB 2.0 , efikelela kwi-approx 480 Mbps.
4. Ulawulo lwamandla
- I-USB 2.0 ibonelela ukuya kuthi ga kwi-500mA amandla unamandla kwiingcinga zakhe.
- I-USB 3.0 ibonelela ukuya kuthi ga kwi-900mA amandla unamandla kwiingcinga zakhe.
Oku kubangela ukunyuka kokunikezelwa kwamandla ewonke ukusuka kwi-2.5W ukuya kwi-4.5W kwi-5V.
Kwaye ngoko, Izixhobo ze-USB 3.0 zinokutshaja ngokukhawuleza xa ziqhagamshelwe kumazibuko e-USB 3.0. njengoko I-USB 3.0 ibonelela ngolawulo olusebenzayo lwamandla kwaye yandisa ukuhanjiswa kwamandla. Naye unako Gcina amandla ngokunciphisa unikezelo kwizixhobo ezingasebenziyo.
5. Ubungakanani boluhlu
- USB 2.0 Lunxibelelwano oluyihafu-duplex, okuthetha ukuba idatha ithunyelwa kwaye ifunyenwe ngendlela efanayo.
Ngoko, USB 2.0 Ukuthumela idatha okanye ukufumana idatha kuphela ngexesha elithile , kodwa hayi zombini. - USB 3.0 Lunxibelelwano olunesiqingatha se-duplex, okuthetha ukuba isebenzisa iindlela ezimbini ezahlukeneyo zedatha yendlela enye. Enye yeyokuthumela idatha kunye neyokufumana idatha.
Kwaye ngoko, I-USB 3.0 ine-bandwidth eninzi kune-USB 2.0.
6. Iintambo ze-USB
- Iintambo ze-USB ze-3.0 zingasetyenziselwa ukuqhagamshela kwi-USB 2.0 kumazibuko kwaye ngokuphambene noko. Kodwa izixhobo ze-USB 3.0 zifuna kuphela iintambo ze-3.0.
Ngoko ke, kubalulekile ukuba utshatise intambo ye-USB kuguqulelo lwezibuko le-USB. - ingafika Iintambo ze-USB 2.0 ziimitha ezi-5 ubude ngelixa phezulu Iintambo ze-USB 3.0 ziimitha ezi-3 ubude Nje.
7. Ixabiso
Lungiselela Izixhobo ze-USB 2.0 zitshiphu kakhulu kunezixhobo ze-USB 3.0. Oku kungenxa yeempawu eziphambili ezibonelela ngazo USB 3.0 , kwaye ulahlekile USB 2.0.
Nangona kunjalo, Izixhobo ze-USB 3.0 zibonelela ngexabiso lemali.
Iintlobo ze-USB
- I-USB 1.0: Ixhasa ukuya kuthi ga kwi-127 peripherals Ukudluliselwa kwedatha ukuya kuthi ga kwi-12 Mbps.
- I-USB 2.0: Yaziswa okokuqala ngonyaka ka-2000 kwaye yaziwa njenge Hi-Speed USB. Ixhasa izixhobo kunye neentambo USB 1.
