Qhov tseem ceeb tshaj plaws yog ua kom tau raws li cov kev xav tau ntawm cov neeg siv khoom los txhim kho kev tsim khoom thiab ua kom muaj txiaj ntsig zoo. Txhawm rau kom cov neeg siv khoom paub ntau ntxiv txog lub tshuab no nrog kev tsim khoom siab thiab kev muag khoom, tab sis kuj tseem txhawb nqa cov txiaj ntsig ntawm lub tshuab thiab cov khoom siv no, kom ntau tus neeg siv tau, peb yuav qhia cov yam ntxwv ntawm lub tshuab thiab cov khoom siv no.

Thawj qhov tshwj xeeb ntawm tsis siv neeg hollow cib tshuab tsis muaj suab nrov heev. Vim tias lub tshuab no thiab cov khoom siv tau txais cov kev ua haujlwm tsis siv neeg, txhua qhov kev sib koom ua ke yog sib koom ua ke thiab txhawb nqa ib leeg kom ua tiav txhua txoj haujlwm. Thiab nyob rau hauv kev tsim ntawm cov khoom no, nws tus tsim qauv, coj mus rau hauv tus account nws qhov chaw ua haujlwm, txhob txwm tshaj tawm qhov nruj ntawm txhua yam khoom zoo heev. Thaum cov khoom siv khiav, yuav tsis muaj kev sib txhuam ntau dhau, yog li yuav tsis muaj suab nrov heev. Qhov thib ob, nws tsim ib qho chaw ua haujlwm zoo heev, nyob ntsiag to.

Qhov thib ob yam ntxwv ntawm lub tshuab tsis siv neeg hollow cib yog tias nws xav tau cov neeg tsawg dua thiab tsis xav tau tus neeg tshwj xeeb kom xa cov khoom siv raw. Nws yog qhov tseeb vim tias qhov tsim ntawm lub tshuab no thiab cov cuab yeej siv tau zoo heev, thiab nws cov kev ua haujlwm tau zoo heev, yog li kev siv lub zog me me, lub tshuab tsuas xav tau ob peb tus neeg ua haujlwm kom ua tiav tag nrho cov txheej txheem tsim khoom, kom cov neeg tsim khoom tuaj yeem txuag tau ntau cov nqi tsim khoom thiab cov nyiaj ua haujlwm. Ntxiv mus, lub tshuab tsis tas yuav ua kom tiav manually ntawm cov khoom siv raw xa los ntawm nws. Hloov chaw, cov txheej txheem ntau lawm yog tswj los ntawm lub computer, yog li cov khoom tsim tawm tsis muaj qhov tsis xws luag ntawm phau ntawv ntau lawm.
