USB-xira. Iyo waxa aannu ku samayn lahaa isaga oo aan?

USB Bus Serial Universal (soo gaabiyay ee "Universal Serial Bus") waa waqti dheer marka la eego horumarinta technology computer - in January 1996. Dadaalka waxaa iska leh horumarinta heerka saarayaasha si fiican u yaqaan ee hardware computer (Compaq, DEC, IBM, Intel , NEC, waqooyiga Telecom). Ujeedada ugu weyn, ayay ag qotomiyeen ku dhiirigelinayaan in uu - si ay awood isticmaala in ay qalabka durugsan ee koronto & hab Play, ie shaqeeyaan marka ku xiran qalab isagoo USB-xira, waxaa si toos ah loo aqoonsaday by computer (u rakibi wadayaasha ku haboon). Sidoo kale la siiyaa qalab yar awood toos ah ku shaqeeya ka daali laftiisa.

Xaaladdan oo kale, xawaaraha baska waa in ay ahaataa oo ku filan muddo ku dhow kasta oo qalabka durugsan. Taasi waa marka motherboards ayaa lagu rakibay Xidhiidhiyayaasha USB 1.0. Ka dib markii la sii daayo 1998, version casriyayn 1.1, taas oo lagu saxo khaladaadka, oo hagaagay xasiloonida hawlgalka, USB-xira waxa uu noqday caadi ah muddo ku dhow kasta computer.

Tallaabada xigta - bixitaanka 2000, USB 2.0, ayaa Heerka this in maalmaha ugu badan. horumarinta A dheeraad ah waxaa si tartiib tartiib ah uu noqdo USB 3.0, isagoo bandwidth badan oo taageera hadda ka badan marka loo eego nuquladii hore (in la siiyo, tusaale ahaan, isticmaalka dibadda HDD), iyadoo la sii Xidhiidhiyayaasha waafaqsan.

Maanta, computer kasta waxay leedahay dekado USB badan (on laptops ay sida caadiga ah 3-4, taagan - 12). Tiradoodu waa la kordhin karaa by xira gaarka ah xarumaha (USB-xarun). Degan computer ah waa hal USB-xira, waxa uu siiyaa dekedaha badan.

Fikrad ahaan suurto gal ah in mar TAWASAL in ay kor u ah computer hal in 127 qalabka USB. Marka xira xarunta loo qaato sida qalab gaar ah (si fudud u gelin, haddii aad isku xiro hal xarun oo afar qalabka, USB-martigeliyaha for tirada qalabka xiran noqon doonaa siman ilaa shan). Iyadoo la tixgelinayo in inta ugu badan ee ku USB-cable, waa 5 mitir. Haddii aad u baahan tahay ka badan, iyada oo aan kordhin gaar ah aan halkan ku samayn kartaa, (waayo, mid kasta oo ka mid ah aagga shan mitir u baahan tahay nooc gaar ah ee Relay in uu leeyahay ah korontada madax bannaan).

The Xidhiidhiyayaasha iyo gelanayo waa laba nooc. isku xira nooca-USB "A" waxaa loo isticmaalaa marka xiran kombiyuutarada desktop iyo laptops USB-qalab kala duwan. Xidhiidhiyayaasha "B" waxay leeyihiin noocyo kala duwan oo xorroyad (tus, madbacadaha, scanners, MFPs). Waxaa jira laba kala duwanaansho ah Xidhiidhiyayaasha nooc labaad - xira mini-USB (loo isticmaalo in lagu xiro qalabka sida kamaradaha digital, PDAs ama taleefanka gacanta), oo isku xira micro-USB ah (xitaa more isafgaradka, sida caadiga ah loo isticmaalo in lagu xiro teleefoonada gacanta).

Isticmaalka caadiga ah USB ah kuu ogolaanayaa inaad isku xiro dhammaan xorroyad casri ah, oo suurto gal ah in ay "kulul" xiriir iyo jarida, sida dhismaha waxaa loogu talagalay la xidhiidha soo noqnoqda iyo jarida khashkhashin waxqabadka sida qalab, iyo sidoo kale computer laftiisa. All taas oo ka dhigaysa interface USB waa xog dhab ah u gaar ah waxay ka dhigan tahay, iyo, laga yaabee, ka duwan lama filayo, ugu yaraan mustaqbalka dhow.
