Iyo nguva yekufambisa-kumhanya-mhanya iri kuuya - USB 4.0
Nhanganyaya
Muna 1994, Intel neMicrosoft vakatanga International Standardization Organisation, inonzi "USB-IF". Sangano rakagadzira nhevedzano yezvakatemerwa uye zvakatemwa zveuniversal serial bus. Pakati pavo, chiyero chakagadziridzwa chakatenderedza kukurumidza kuchaja ndiyo inozivikanwa USB PD protocol, iri parizvino imwe yeanonyanya kushandiswa veruzhinji kubhadharisa mapuroteni, uye tsvakiridzo yeindasitiri ecology yePD 3.1 yakaburitswa pamberi pemusoro wekuchaja. network yaburitsa chinyorwa chakareba, munhu anogona kunzwisisa iyo yese indasitiri chain yePD 3.1.
Pamusoro pezvo, USB-KANA yakagadzira chiyero chekufambisa data, uye yakananga zita rekuti USB #.0, mushure meshanduko yazvino vhezheni, yazvino kutsanangurwa kwe USB ndeye USB4, chinyorwa ichi chichanyura mu USB4 kubva pakuburitswa kwayo, mumusika. kuvaka indasitiri ye ecology.
Nezve USB4
USB's data transfer protocol yakaburitswa kare kupfuura USB PD, uye USB1.0 yakaunzwa muna 1996, gore rechitatu mushure mekunge USB-IF yatangwa. Chizvarwa chekutanga che USB chiyero, mwero wekutapurirana ingori 1.5Mbps, iwo ruzivo rwekuvandudzwa kwe USB nhoroondo vhezheni ndapota ona tafura inotevera:
MunaGunyana 2019, USB4 yakaburitswa zviri pamutemo nehupamhi hwekutapurirana hwe40Gbps, yakafanana neThunderbolt 3. USB4 ine zvirevo zviviri, zvichiteerana, USB4 40 ine bandwidth yakakura ye40Gbps, USB4 20 ine bandwidth yakakura ye20Gbps, uye vatengi vanoda. kuziva kuti USB4 40 izere ropa interface.
MunaGunyana 2022, iyo USB4 2.0 yakajairwa yakafumurwa pachine nguva, mwero wepamusoro wakawedzerwa kusvika 80Gbps, dhizaini nyowani yakagamuchirwa, uye USB PD yekukurumidza kuchaja standard, USB Type-C interface uye tambo standard yaizogadziridzwa zvakare synchronously.
Zvinogona kuonekwa kuti mukugadzirisa shanduro yekushandura, kuchinja kukuru ndiko kuvandudzwa kwehuwandu hwekutumira data, kubva pakatanga 1.5Mbps kusvika kune ikozvino kuratidzwa kwe USB4 2.0 yasvika 80Gbps, kuwedzera kwemakumi ezviuru zvenguva. Shanduko iyi inonyanya kukonzerwa nekukwidziridzwa kwechiteshi chekufambisa data, kubvira 2013, iyo USB3 yakatevedzana vhezheni, yakawedzera kusvika 4 mapeya ematanho akasiyana, uye akashongedzerwa nekuita zvirinani USB-C chiteshi, zvichiita kuti data kufambisa kuve nekuvandudzwa kwehunhu.
Parizvino, kune zvigadzirwa zvakawanda zvinoshandisa iyo yepamusoro-yekumhanyisa data data basa reiyo USB-C interface, kunyanya mamwe ekunze ekuchengetera midziyo (senge yakakwira-speed solid-state drives, high-speed transmission cables, uye mainterface anoshandiswa zvakananga mukati. mamwe mabhuku epamusoro-soro).
