Yog tias qhov kev ua haujlwm ntawm lub qhov (socket) vuam siv tshuab yuav tsum tau lav, raws li cov chaw tsim khoom, ua ntej txhua yam, nws yog qhov tsim nyog los xyuas kom meej tias nws tus kheej cov khoom lag luam tsim khoom siv ua khoom ua haujlwm. Cov khoom siv ua tiav raw khoom yuav los ntawm cov tsim khoom lag luam tuaj yeem ua tau zoo thiab ua tau zoo, yog li ntawd. Nws yog qhov ua tau rau cov cuab yeej siv tshuab vuam siv los ua kom muaj kev ua haujlwm zoo. Qhov no yog vim hais tias qhov kawg ua tiav ntawm cov khoom siv txuas nrog qhov ua tau zoo thiab ua tiav ntawm cov ntaub ntawv nyoos, thiab tsuas yog cov khoom siv zoo siab tuaj yeem tsim cov khoom siv hluav taws xob zoo ntawm cov vuam siv.
Lub qhov (socket) vuam tshuab ua tshuab, yog tias lawv xav tsim cov cuab yeej siv nrog kev ua haujlwm zoo, tsis tas yuav tsum ua haujlwm zoo hauv kev ua kom tiav cov khoom siv raw, tab sis kuj tseem xav tau ua haujlwm zoo hauv lav lawv cov cuab yeej tsim khoom. Qhov ntau tshaj thiab kev txawj siv tshuab thev naus laus zis tau txais los ntawm tus tsim khoom, kev ua tau zoo dua ntawm cov khoom siv raw tuaj yeem kis mus rau cov khoom siv vuam tsim hauv qhov kawg nkaus.
