Thaum kaj ntug ntawm lub thev naus laus zis thev naus laus zis, ib qho teeb meem tseem ceeb ntawm tus neeg siv yog qhov tsis zoo ntawm cov khoom siv - ntau qhov chaw nres nkoj tau ua lub luag haujlwm sib txuas rau cov khoom siv, feem ntau cov khoom siv loj thiab tsis ntseeg siab. Txoj kev daws teeb meem yog "npav tos neeg caij npav" lossis, hais luv, USB. Thawj thawj zaug, qhov chaw nres nkoj tshiab tau nthuav tawm rau cov pej xeem sawv daws rov qab rau xyoo 1996. Hauv xyoo 2001, cov motherboards thiab cov cuab yeej sab nraud USB 2.0 tau los ua cov neeg siv khoom, thiab xyoo 2010 USB 3.0 tau tshwm sim. Yog li dab tsi yog qhov sib txawv ntawm cov thev naus laus zis thiab vim li cas ob leeg tseem nyob hauv kev thov?
Qhov sib txawv ntawm USB 2.0 thiab 3.0
Ua ntej tshaj plaws, nws tsim nyog sau cia tias txhua lub chaw nres nkoj USB yog sib haum nrog txhua tus. Qhov no txhais tau tias kev sib txuas cov khoom siv qeeb mus rau qhov chaw nres nkoj nrawm thiab hloov chaw dua yog ua tau, tab sis cov ntaub ntawv txauv cov ntaub ntawv yuav tsawg heev.
Koj tuaj yeem "txheeb xyuas" tus qauv ntawm cov txuas sib txuas ua kom pom - nrog USB 2.0 sab hauv sab hauv yog pleev xim dawb, thiab nrog USB 3.0 - xiav.

Ib qho ntxiv, cov xaim xov tshiab tsis suav nrog plaub, tab sis ntawm yim tus xov hlau, uas ua rau lawv ua cov tuab tuab dua thiab tsis ua haujlwm. Ntawm ib sab tes, qhov no nce qhov kev ua haujlwm ntawm lub cuab yeej, txhim kho cov ntaub ntawv hloov chaw, thiab ntawm qhov txuas ntxiv, nws nce tus nqi ntawm cov cable. Raws li txoj cai, USB 2.0 cable yog 1.5-2 zaug ntev dua lawv cov neeg txheeb ze "ceev". Muaj qhov sib txawv ntawm qhov loj me thiab kev teeb tsa ntawm cov qauv sib xws ntawm cov txuas. Yog li, USB 2.0 tau muab faib ua:
- hom A (li qub) - 4 × 12 hli;
- hom B (li qub) - 7 × 8 hli;
- hom A (Mini) - 3 × 7 hli, trapezoidal nrog cov fab sib npaug;
- hom B (Mini) - 3 × 7 hli, trapezoidal nrog cov ces kaum txoj cai;
- hom A (Micro) - 2 × 7 hli, duab plaub;
- hom B (Micro) - 2 × 7 hli, plaub nrog duab sib npaug.
Hauv cov khoom siv khoos phis tawm, USB hom A li ib txwm siv feem ntau, hauv cov khoom siv txawb - Hom B Mini thiab Micro. Kev faib tawm ntawm USB 3.0 kuj tseem nyuaj:
- hom A (li qub) - 4 × 12 hli;
- hom B (li qub) - 7 × 10 hli, cov duab puab;
- hom B (Mini) - 3 × 7 hli, trapezoidal nrog cov ces kaum txoj cai;
- hom B (Micro) - 2 × 12 mm, duab plaub nrog cov ceg kaum sib npaug thiab rov ua haujlwm;
- hom C - 2.5 × 8 mm, duab plaub nrog sib npaug.
Hom A tseem nyob hauv cov khoos phis tawj, tab sis Hom C tau txais ntau dua thiab nrov dua txhua hnub. Qhov hloov kho rau cov qauv no tau qhia hauv daim duab.

Nws yog ntxov dhau los sau tawm USB 2.0 los ntawm cov nyiaj - tus qauv no yog siv dav siv los txuas cov keyboards, nas, tshuab luam ntawv, ntawv ntsuas, thiab lwm yam khoom siv sab nraud, thiab siv tau hauv cov khoom siv mobile. Tab sis rau flash drive thiab sab nraud drives, thaum nyeem thiab sau ceev yog thawj, USB 3.0 yog qhov zoo dua. Nws tseem tso cai rau koj txuas ntau cov cuab yeej rau ib lub hub thiab them cov roj teeb sai dua vim tias lub zog tam sim no ntau dua.
