Tafole ea likateng

Litekanyetso tsa Universal Serial Bus (USB) li fetotse tsela eo re hokahanyang lisebelisoa tsa rona ka eona. Lekhalo pakeng tsa USB 2.0 le USB 3.2 joale le bohlokoa ho feta. Sengoliloeng sena se sheba matla le mefokolo ea e 'ngoe le e' ngoe, le hore na e ama basebelisi joang.

Lintlha tsa bohlokoa

USB 2.0 le USB 3.2 ke mahlale a fapaneng a USB, a nang le lintlafatso tse kholo lebelong le ts'ebetsong.

Ho tseba liphapang tse kholo, joalo ka litefiso tsa phetisetso ea data le phano ea matla, ho thusa ho ntlafatsa ts'ebetso ea sesebelisoa le ho lumellana.

Ho khetha maemo a nepahetseng a USB ho ipapisitse le litlhoko tsa hau le litlhoko tsa sesebelisoa bakeng sa boiphihlelo bo botle ka ho fetisisa.

Maemo a USB a fetohile ho tsamaisana le tlhoko ea phetiso ea data e potlakileng le lisebelisoa tse matla haholoanyane.

Ho tsamaisana le liapdeite tsa USB ho thusa basebelisi ho etsa khetho e betere le ho ikamahanya le theknoloji e ncha.

Ho utloisisa mefuta ea USB

Ho utloisisa phapang lipakeng tsa USB 2.0 le USB 3.2, re hloka ho sheba hore na theknoloji ea USB e holile joang. Ho tloha ho USB 2.0 e tloaelehileng ho ea ho USB 3.x e ncha, ntlafatso ka 'ngoe e entse liphetoho tse kholo. Liphetoho tsena li kenyelletsa phetiso ea data e potlakileng, matla a mangata, le ts'ebetso e ntle.

USB 2.0

USB 2.0 e tsoile ka 2000 mme kapele ea fetoha khetho e holimo bakeng sa ho tsamaisa data le lisebelisoa tsa ho hokahanya. E ka tsamaisa data ka sekhahla sa 480 Mbps, ho tlola ho hoholo ho tloha ho USB 1.1 ea khale. Kajeno, lisebelisoa tsa USB 2.0 li ntse li tumme bakeng sa lintho tse kang ho boloka lifaele le ho tjhaja mehala.

USB 3.0, 3.1, le 3.2

USB 3.0 e fihlile ka 2008 mme e bile mohato o moholo oa ho nyoloha. E ka tsamaisa data ho 5 Gbps, e hlahisa "SuperSpeed" USB. Sena se ne se bolela ho fetisoa ha data ka potlako le tšebeliso e ntle ea matla. Ho tloha ka nako eo, USB 3.x e 'nile ea ntlafala, ka USB 3.1 le 3.2 tse fanang ka lebelo le potlakileng le likarolo tse ling.

USB 3.1(e tsejoang hape e le SuperSpeed +) e tsoile ka 2013. E ile ea eketsa sekhahla sa data habeli ho 10 Gbps, e leng se etsang hore e be molemo bakeng sa mesebetsi e hlokang boitsebiso bo bongata.

USB 3.2, e lokollotsoeng ka 2017, e tlisitse likhetho tse potlakileng le ho feta. E kenyelletsa USB 3.2 Gen 1 (ho fihla ho 5 Gbps), USB 3.2 Gen 2 (ho fihla ho 10 Gbps), le USB 3.2 Gen 2x2 (ho fihla ho 20 Gbps). Mabelo ana a fihlela litlhoko tsa lisebelisoa tsa kajeno le lisebelisoa.

Lintlafatso tse ho USB 3.x li fetotse mokhoa oa ho fetisa data. Ba etsa hore ho arolelana lifaele ho be bonolo, ho boloka li-backups kapele, le ho shebella livideo hantle. Ho tseba ka mefuta e fapaneng ea USB ho thusa basebelisi ho khetha tse ntle bakeng sa lisebelisoa tsa bona le ho fumana molemo ka ho fetisisa ho tsona.

Phapang ea Bohlokoa lipakeng tsa USB 2.0 le USB 3.2

Ho utloisisa phapang pakeng tsa USB 2.0 le USB 3.2 ke senotlolo. Liphapang tsena li akaretsa lebelo la phetisetso ea data, likhokahano tsa 'mele le tšebelisano, phano ea matla, le khouto ea data le bokhoni.

Mabelo a Phetiso ea Lintlha

USB 3.2 e na le lebelo le leholo la phetisetso ea data ha e bapisoa le USB 2.0. USB 2.0 e holimo ho 480 Mbps, ha USB 3.2 e ka fihla ho 20 Gbps. Sena se bolela ho fetisoa ha lifaele ka potlako, ho phalla ha video ho bonolo, le ho boloka boitsebiso ka potlako.

Lihokahanyo tsa 'Mele le ho lumellana

USB 2.0 e sebelisa lihokelo tsa USB-A le USB-B. USB 3.2 e hlahisa USB-C, e ka khutlisetsoang morao hape e ts'ehetsa USB Power Delivery le DisplayPort. Sena se etsa hore lisebelisoa tse hokelang li be bonolo le ho feta.

Phano ea Matla

USB 3.2 e fana ka matla a betere ho feta USB 2.0. E ka fetisa matla a fihlang ho 100W, a lekaneng ho tjhaja lilaptop le lisebelisoa tse matla haholo ka khokahanyo ea USB.

Khouto ya Ditaba le Bokgoni

USB 3.2 e boetse e na le khouto ea data le katleho e ntle ho feta USB 2.0. E sebelisa sekema se tsoetseng pele sa khouto le theknoloji ea lipontšo bakeng sa phetiso ea data e potlakileng le tšebeliso e fokolang ea matla. Sena se bolela ts'ebetso e ntle le bophelo bo bolelele ba betri bakeng sa lisebelisoa tse hokahaneng ka USB 3.2.

Phapano lipakeng tsa USB 2.0 le USB 3.2 e bonts'a lintlafatso tse kholo lebelong la phetisetso ea data, khokahanyo ea 'mele, phano ea matla, le ts'ebetso ea data. Ka USB 3.2, basebelisi ba fumana boiphihlelo bo potlakileng, bo feto-fetohang ha ba hokahanya lisebelisoa.

Liphello Tse Sebetsang ho Basebelisi

Khetho pakeng tsa USB 2.0 le USB 3.2 e bohlokoa bakeng sa basebelisi ba lisebelisoa tsa USB le li-peripheral. Ho tseba phapang ho thusa ho etsa khetho e ntle. Sena se netefatsa ts'ebetso e ntle ka ho fetisisa le taolo ea matla ea usb ea li-usb hubs le li-adapter tsa usb.

Tšebelisano ea lisebelisoa

Ha u khetha pakeng tsa USB 2.0 le USB 3.2, nahana ka tšebelisano ea lisebelisoa. USB 3.2 e na le sebopeho se betere sa usb le likarolo tsa protocol tsa usb. Empa, etsa bonnete ba hore lisebelisoa tsa hau tsa usb le li-peripheral tsa usb li sebetsa le eona.

Lisebelisoa tsa khale li kanna tsa se tšehetse likarolo tse tsoetseng pele tsa USB 3.2. Sena se bolela hore o kanna oa hloka ho sebelisa USB 2.0 le USB 3.2 bakeng sa litlhoko tse fapaneng.

Mehopolo ea Ts'ebetso

Khetho pakeng tsa USB 2.0 le USB 3.2 e ama tsela eo lintho li sebetsang hantle ka eona. Bakeng sa mesebetsi e meholo joalo ka ho hlophisa video kapa li-backups tsa faele, lebelo le potlakileng la USB 3.2 ke tlatsetso e kholo. Empa, bakeng sa mesebetsi e bonolo, phapang e kanna ea se be kholo joalo.

Kahoo, basebelisi ba ka khetha USB 2.0 bakeng sa mesebetsi ea letsatsi le letsatsi, leha e sa potlake.

Melemo ea Phano ea Matla

Nahana ka phepelo ea matla ha u khetha pakeng tsa USB 2.0 le USB 3.2. USB 3.2 e na le taolo e betere ea matla a usb. Sena se bolela ho tjhaja kapele le matla a mangata bakeng sa lisebelisoa tse kang lilaptop le mehala.

Sena se nepahetse bakeng sa basebelisi ba hlokang matla a ka tšeptjoang le a sebetsang hantle a usb bakeng sa litlhoko tsa bona tsa letsatsi le letsatsi.

Qetello

Ho tloha ho USB 2.0 ho ea ho USB 3.2 ho tlisitse liphetoho tse kholo. Liphetoho tsena li kenyelletsa phetisetso ea data e potlakileng, matla a mangata, le ts'ebetso e ntle. Tšebeliso e ntseng e hola ea li-USB e khanna mehopolo e mecha le ho bopa bokamoso. Bakeng sa likhoebo le liindasteri tse hlokang lits'ebetso tsa khomphutha tse tšepahalang le tse ka senyehang,lik'homphieutha tsa rackmount tse matsutlafana ka ts'ebetso e tšoarellang le ts'ebetso e hlokahalang ho matlafatsa likhetho tsa khokahanyo tse tsoetseng pele joalo ka USB 3.2.

Mabelo a USB 3.2 a ho fihla ho 20Gbps a nepahetse bakeng sa mesebetsi e kang ho phallela livideo tsa 4K le ho tsamaisa lifaele tse kholo. E boetse e nolofalletsa lisebelisoa tsa ho hokahanya. Haeba kopo ea hau e hloka litsamaiso tse sebetsang hantle, tse sebetsang hantle, nahana ka aPC e kenyellelitsoeng indastering e se nang fan. Hape, USB 3.2 e fana ka likhetho tse betere tsa ho tjhaja, kahoo o ka boloka lisebelisoa tsa hau li lefisoa kae kapa kae. E le moetapelemoetsi oa lik'homphieutha tsa indasteri, SINSMART TECH e netefatsa hore litsamaiso tsa eona li hlomelloa ho sebetsana le likhatelopele tsena ka nepo.

USB 4.0 le ho phahama ha lihokelo tsa USB-C li hlophiselitsoe ho tlisa lintlafatso le ho feta. Bakeng sa liindasteri tse hlokang litlhophiso tse matla, aK'homphieutha ea 4U rackmountke khetho e nepahetseng bakeng sa ho tšehetsa bokhoni ba USB ba lebelo le holimo. Ho feta moo,Li-PC tse kentsoeng tsa Advantechli etselitsoe ho fihlela litlhoko tsa lits'ebetso tse tsoetseng pele tsa indasteri tse ruang molemo ho lintlafatso tsena tsa khokahano.

Ha li-USB li ntse li ntlafala, re ka lebella ts'ebetso e potlakileng, likhokahano tse ngata, le ho lumellana lilemong tse tlang. Bakeng sa ba batlang ho kenyelletsa theknoloji ea USB ea sejoale-joale litsamaisong tsa bona, ba sebelisana le ba nang le boiphihlelobaetsi ba PC ba kentsoenge netefatsa katleho ea nako e telele. Sena se tla re thusa ho tsamaisana le bophelo ba rona ba dijithale.
