USB 2.0 vs. USB 3.0 vs. USB 3.1 Type-C: chii chakasiyana? 3l4p13

6w40b

Um kudzidza yakagadzirwa na Multimedia Research Group inoratidza kuti, ne2016, kutengesa kwemidziyo USB 3.0 kusvika 2,4 bhiriyoni mayuniti, kukura kwe540% zvichienzaniswa ne2012. Asi vanhu vazhinji vachiri kutenga pamhepo, vasingazivi musiyano chaiwo pakati pehunyanzvi hwekare (USB 2.0) ndiyo itsva USB 3.0. Tinotsanangura pasi apa:

Kutanga, mavambo: 4x3a29

Inyanzvi USB yakaonekwa muna 1994 uye, kubvira ipapo, yakadzokororwa kakawanda. Iyo inonyanya kufarirwa ndeye shanduro 1.1 e 2.0, iyo yekupedzisira ichiri kushandiswa zvakafara. Yekutanga inokwanisa kuwana, kunyanya, mitengo yekutapurirana kwe 12 Mb / s (megabits pasekondi), nepo iyo vhezheni 2.0 anogona kupa kusvika 480 Mb / s (iyo inoenderana ne60 megabytes pasekondi).

Asi nhamba ye-high-speed internet connections yakakura nekufamba kwenguva, zvichiita kuti vanhu vade kudya mavhidhiyo, mimhanzi, mapikicha nemitambo mukutsanangurwa kwepamusoro. Mune mamwe mazwi, mafaera ari kukura uye kukura, uye izvi zvinoda matekinoroji matsva ekukurumidza kutamisa data.

Nekutsanangurwa kwayo kwekupedzisira kwakaziviswa munaNovember 2008, iyo USB 3.0 yakabuda kuti isangane nechikumbiro ichi.

USB3.0: 3r25e

Zvakare kunzi Super Speed ​​​​USkana USB 3.0 inyanzvi yekufambisa data kusvika ku60 nguva nekukurumidza kupfuura chizvarwa chakapfuura, nekumhanya kwekuverenga kunosvika kusvika 4,8 Gb / s (5 Gb/s, rounding off), iyo inoenderana ne600 megabytes pasekondi (zvichienzaniswa ne 480 Mb / s  kana 60 megabytes pasekondi ye USB 2.0).

Iyi tekinoroji zvakare inomira pachena pakunyanya kushanda kwayo kwesimba: iyo USB 2.0 inoshanda neazvino kusvika 500 miriyoni uye kunetsana kwe 5 volts, nepo shanduro itsva inogona kutsigira 900 miriyoni e 5 volts. Mune mamwe mazwi, inogona kugonesa zvishandiso zvinopedza simba rakawanda, kudzivirira kuwedzera nekunze magetsi masosi (zvigadziko).

Nezve kuendesa data pachako, iyo USB 3.0 Inoita basa iri bidirectionally, ndiko kuti, pakati pemidziyo yakabatana, zvinokwanisika kutumira uye kugamuchira data panguva imwe chete. Pa USB 2.0, rudzi rumwe bedzi rwebasa rinobvira panguva.

Zvakanakira zvechizvarwa chekare, izvo zvichiri kuenderana USB 3.0, zvakare chikamu chepasuru: rutsigiro Dzvanya & Tamba (plug uye tamba, hapana chikonzero chekuisa madhiraivha), kushandiswa kweanopfuura mudziyo mumwe pane imwechete USB port; uye Kupisa Kunopisa (kukwanisa kubatanidza uye kubvisa zvishandiso pasina kudzima kutanga).

Mhando dzeConnector: 3j5c6o

Zvakanaka, pano zvinhu zvinowedzera kuoma. Zvichienderana nebasa kana midziyo inoshandiswa, USB connector inogona kuva nehukuru hwakasiyana uye maumbirwo.

Imwe yemigumo inogara iine iyo rectangular kutaridzika, yakajairwa ye USB, ine maitiro maviri chete akasiyana kubva kune imwe. USB 2.0: pachinzvimbo chedema, chibatanidza USB 3.0 Iblue, ine logo"SS” (inobva ku “Super Speed”, kana kumhanya kukuru, mushanduro yemahara). Inonzi connector USB 3.0A.

Kana iri imwe magumo, iyi inogona kunge iri yemhando USB 3.0A, B (ine chitarisiko che square, chinoshandiswa mumaprinta kana scanner), Micro ou Mini USB (iine mamwe macompact maficha, anoshandiswa mune akawanda ma-smartphones uye mahwendefa). The standard "B” inogadzirwa zvakare mu "usb powered”, iyo inopa kusvika 1000 miriyoni yesimba kumidziyo yakabatana.

Pane muganhu here pakukura kweCable? 1z6j4g

Kana iri saizi yetambo, hapana muganhu wakatsanangurwa. Nekudaro, bvunzo dzinoitwa neakasarudzika masangano anokurudzira huwandu hunosvika 3 metres kuti ishandiswe zvizere tekinoroji. Mushure meichi chiyero, kune kurasikirwa kukuru muyero yekufambiswa kwedata uye nekumhanyisa kunochajwa majeti akabatana.

Uye Ramangwana? (USB 3.1 uye USB-C Connector): 3r4oi

Muna August 2013, the USB.org yakazivisa zvakatemwa zvekupedzisira zve USB 3.1 (inozivikanwawo se SuperSpeed ​​​​USB 10Gbps) Inovavarira kupa mareti ekufambisa data kusvika 10 Gb / s (yakaenzana ne1,2 gigabytes pasekondi).

Pano, hapana kuchinja kwakakosha mune chiyero 3.0. "Chakavanzika", kunyanya, chinogara mukushandisa nzira yakanyanyisa yekodhi yekodhi iyo, panguva imwechete, haiiti kuti teknolojia iwedzere kudhura. Uye, nekuda kwekutsanangurwa kunodanwa USB Simba Kuendesa, Single USB 3.1 chiteshi inogona kupa kusvika ku100 watts (ikozvino inosvika ku5 amps uye voltage inosvika makumi maviri volts).

Chimwe chinhu chitsva chave chiripo kubva Nyamavhuvhu 2014, asi chave kutanga kuoneka pamagajeti nemidziyo, USB Type-C connector (USB Type-C, muchirungu).

Chiyero chinonyanya kukwezva kutorwa kwechibatanidza reversible: chibatanidza USB-C Unogona kuva yakaiswa kune chero rutivi pamusuwo USB.

Nekugadzirira kushanda ne USB 3.1, chibatanidza USB-C inogonawo kubata kusvika 100 watts - magetsi anosvika 3 amps pane yakajairwa tambo uye 5 amps pane yekubatanidza pachayo. Saka, tambo imwe chete inogona kushandiswa zvese kune data traffic uye kune magetsi ekupa kune mamwe maturusi.

Chimwe chinonakidza chimiro che USB-C ndiyo Alternate Mode (mushanduro yemahara, Alternative Mode). Nechinhu ichi, vagadziri vanogona kugadzira mamwe mashandiro etambo uye mapimendi muyero.

Muenzaniso inobva kuVESA (Vhidhiyo Electronics Standards Association) Sangano rakaita kuti shanduro dzichangoburwa dzetekinoroji dzienderane DisplayPort ne USB-C. Saka, mudziyo (wakaita selaptop) une chinopinza chinosanganisa ese zviyero (USB neDisplayPort) uchakwanisa kufambisa mavhidhiyo kuTV kana kutarisa mu4K resolution kana kupfuura.

Unoda kuziva zvakawanda? Shanyira webhusaiti USB.org (muChirungu) uye Wikipedia. Uyewo tarisa kunze kwe mameseji kubva pawebhusaiti Infowester, yakashandiswa senongedzero yebhuku rino.
