U-Michal Ždanský Njengoba bekulindelekile, ama-MacBooks amasha athole imbobo entsha enesivinini esikhulu iThunderbolt (LightPeak), namanye amakhompyutha akwa-Apple azolandela okufanayo. Kulesi sihloko, ngithanda ukubheka kabanzi i-Thunderbolt ehlonishwayo, kokubili ngokombono wezobuchwepheshe kanye nethiyori.
I-Thunderbolt ngaphansi kwengilazi yokusondeza
Nakuba i-LightPeak ikhulume ikakhulukazi ngokudluliswa kwe-fiber optical, i-Thunderbolt, evele ku-MacBook Pro, i-metallic, okungukuthi ukuhanjiswa kusekelwe kuma-electron, hhayi ama-photons. Lokhu kusho ukuthi singaphupha kuphela ngesivinini sethiyori esingu-100 Gb/s okwamanje, kanye nezintambo ezingaba ngu-100 m. Ngakolunye uhlangothi, ngenxa yama-electron, i-Thunderbolt ingaphinde ishaje amadivaysi angenayo kuze kufike ku-10 W, futhi intengo izoba ngaphansi kakhulu ngenxa yokungabikho kwama-optics. Ngicabanga ukuthi inguqulo yesikhathi esizayo ye-optical izoqukatha ingxenye yensimbi ukuze ishaje.
I-Thunderbolt isebenzisa i-PCI Express 2.0 interface exhumana ngayo. Inomphumela ofinyelela ku-16 Gb/s. I-PCI Express manje isisetshenziswa kakhulu amakhadi ezithombe. Ngakho-ke, i-Thunderbolt iba uhlobo lwe-PCI Express yangaphandle, futhi esikhathini esizayo singalindela namakhadi ezithombe zangaphandle axhunywe ngesixhumi esibonakalayo esisha se-Intel.
I-Thunderbolt, okungenani njengoba yethulwe yi-Apple, ihlanganiswe ne-DisplayPort encane ekubuyekezweni kwe-1.1 futhi ivumela ukuhambisana nayo emuva. Ngakho-ke uma uxhuma, ngokwesibonelo, i-Apple Cinema Display nge-Thunderbolt, izosebenza ngokujwayelekile, noma ngabe ukuqapha kwe-Apple kungakabi nayo i-Thunderbolt.
Okuthakazelisa kakhulu ukuthi isixhumi esibonakalayo esisha sineziteshi ezimbili futhi siqondiswa kabili. Ngakho-ke ukusakazwa kwedatha kungasebenza ngokuhambisana, okuholela ekudlulisweni kwedatha okuphelele kufika ku-40 Gb/s, kodwa ngeqiniso lokuthi isivinini esiphezulu sesiteshi esisodwa siseyi-10 Gb/s. Ngakho-ke ilungele ini? Isibonelo, ungashintshanisa idatha phakathi kwamadivaysi amabili ngesikhathi esisodwa ngesivinini esiphezulu ngangokunokwenzeka ngenkathi uthumela isithombe kumqaphi wangaphandle.
Ngaphezu kwalokho, i-Thunderbolt iyakwazi lokho okubizwa ngokuthi "i-daisy chaining", okuyindlela yokuhlanganisa amadivaysi. Ngale ndlela, ungakwazi ukuxhuma nge-serial kumadivayisi ayi-6 ngembobo ye-Thunderbolt ezosebenza njengamadivayisi wokufaka/okukhiphayo kanye neziqapha ezifika kwezi-2 ezine-DisplayPort ekugcineni kweketango (ngeziqaphi ezimbili kuzoba yimishini emi-5), eyenza akudingekile ukuba ne-Thunderbolt. Ngaphezu kwalokho, i-Thunderbolt inokubambezeleka okuncane (8 nanoseconds) kanye nokuvumelanisa okunembe kakhulu kokudlulisa, okubalulekile hhayi kuphela ku-daisy chaining.
Umbulali we-USB 3.0?
I-Thunderbolt isongela kakhulu i-USB 3.0, esakhula kancane kancane. I-USB entsha inikeza isivinini sokudlulisa esingafika ku-5 Gb/s, okusho ukuthi uhhafu womthamo we-Thunderbolt. Kodwa lokho i-USB engakunikezi yizinto ezifana nokuxhumana kweziteshi eziningi, i-daisy chaining, futhi angilindele nokusetshenziswa kokukhiphayo okuyinhlanganisela ye-A/V. Ngakho-ke i-USB 3.0 iyingane yakubo esheshayo yenguqulo ekabili yangaphambili.
I-USB 3.0 ingaxhunywa ngaphezu kwalokho ebhodini lomama nge-PCI-e, ngeshwa iThunderbolt ayikuvumeli lokhu. Idinga ukusetshenziswa ngokuqondile ebhodini lomama, ngakho-ke uma ubucabanga ukwengeza i-Thunderbolt ku-PC yakho, kufanele ngikudumaze. Kodwa-ke, singalindela i-Intel futhi ekugcineni nabanye abakhiqizi bebhodi lomama ukuthi baqale ukuyisebenzisa emikhiqizweni emisha.
I-Thunderbolt ngokungangabazeki iyimbangi eqondile ye-USB entsha, futhi kuzoba nempi eshubile phakathi kwakho kokubili. I-USB isivele ilwe impi efanayo ngesixhumi esibonakalayo esisha se-FireWire. Kuze kube namuhla, i-FireWire isiphenduke inkinga encane, kuyilapho i-USB ikhona yonke indawo. Nakuba i-Firewire inikeze isivinini sokudlulisela esiphezulu, yaphazanyiswa yilayisense ekhokhelwayo, kuyilapho ilayisense ye-USB yayimahhala (ngaphandle kwenguqulo ekhethekile ye-USB enesivinini esikhulu). Kodwa-ke, i-Thunderbolt ifundile kuleli phutha futhi ayidingi imali yelayisensi evela kubakhiqizi bezinkampani zangaphandle.
Ngakho-ke uma i-Thunderbolt iwina indawo yayo elangeni, umbuzo uzoba ukuthi i-USB 3.0 izodingeka nhlobo. Ukuhambisana ne-USB kusazokwaziwa nge-Thunderbolt ngokunciphisa, futhi i-USB 2.0 yamanje izokwanela ukudluliswa kwedatha okuvamile kwama-flash drive. Ngakho-ke i-USB entsha izoba nesikhathi esinzima, futhi phakathi neminyaka embalwa iThunderbolt ingase iyikhiphe ngokuphelele. Ngaphezu kwalokho, abadlali aba-2 abanamandla kakhulu bame ngemuva kweThunderbolt - Intel ne-Apple.
Kuyoba kuhle ngani?
Uma singakhuluma ngesikhathi samanje, khona-ke i-Thunderbolt ayisetshenziswa ekusebenzeni, ikakhulukazi ngenxa yokungabikho kwamadivayisi analesi sikhombimsebenzisi. Akumangazi, i-Apple yaba ngowokuqala ukwethula i-Thunderbolt ezincwadini zayo zokubhalela, ngaphezu kwalokho, ukuhluka kuqinisekiswa izinyanga eziningi, okungenani mayelana nokuhlanganiswa kumabhodi omama.
Kodwa-ke, abanye abakhiqizi baqala ukudlala ngothando nge-Thunderbolt. I-Western Digital, Promise a I-LaCie sebevele bamemezele ukukhiqizwa kokugcinwa kwedatha namanye amadivaysi ane-Intel interface entsha, futhi kungalindeleka ukuthi abanye abadlali abaqinile abanjengo. Seagate, Samsung, Idatha nokuningi kuzokwengezwa maduze, njengoba abambalwa bazofuna ukuphuthelwa yigagasi elisha abangagibela kulo ngokuduma. I-Apple isiwuhlobo lophawu lwesiqiniseko mayelana nokuqaliswa kobuchwepheshe obusha, futhi iningi lobuchwepheshe elibusebenzisile selicishe laba yinto evamile esikhathini esithile, liholwa yi-USB yasekuqaleni.
Singalindela ukuthi i-Apple izofuna ukusebenzisa i-Thunderbolt emikhiqizweni yayo eminingi. Ukubuyekezwa okusha kwe-Time Capsule cishe kuqinisekile ngo-100%, njengama-iMacs amasha namanye amakhompyutha we-Apple azokwethulwa maduze nje. Ukuthunyelwa kungalindelwa kumadivayisi e-iOS, lapho i-Thunderbolt izongena esikhundleni sesixhumi esikhona sedokhi. Ngeke kushiwo ngokuqinisekile ukuthi kuzoba kulo nyaka, kodwa bengizofaka isandla sami emlilweni ngenxa yokuthi i-iPad 3 ne-iPhone 6 ngeke zisawugwema.
Uma i-Thunderbolt iphumelela ngempela ukufohla phakathi kwamadivayisi e-I/O, singase silindele inqwaba yemikhiqizo enalesi sikhombimsebenzisi ekupheleni konyaka. I-Thunderbolt ishintshashintsha kakhulu kangangokuba ingakwazi ukuvala isikhala sazo zonke izixhumi zefa kanye nezixhumi zesimanje ezifana ne-HDMI, i-DVI ne-DisplayPort ngaphandle kokucwayiza iso. Ekugcineni, asikho isizathu sokuthi kungani ingakwazi ukumiselela i-LAN yakudala. Konke kuncike ekusekelweni kwabakhiqizi kanye nokuthembela kwabo ku-interface entsha futhi, okokugcina, ekuthembekeni kwamakhasimende.

Hawu. Hhayi-ke, ihlaya lelo :)
Akukho okunye esingakusho ngalokho, hhayi WOOOOW…!!! Ngibheke ngabomvu isikhathi lapho ngizoba ne-mini-pidi Mabook Air lapho izosebenza kahle emgwaqweni futhi lapho ngifika ekhaya ngiyixhume ku-Cinema entsha futhi izoba nezithombe ezinamandla kanye nesistimu yomsindo esetshenziswayo. kuyo futhi angazi ukuthi yini enye futhi ngokuzumayo izoba umshini onamandla wokusetshenziswa okungokoqobo noma yini. Kuyoba kuhle lokho mnumzane. Noma ithebhulethi kanye nesinema nakho kungaba kuhle :-)
