Qhov tseem ceeb ntawm kev siv computer cables yog kev xa cov ntaub ntawv.

Kev lag luam tiam sis qhia tau hais tias cov khoom siv cable hloov tau hloov mus rau kev txawj ntse thiab eco-kev ua haujlwm zoo.

Thaum xaiv cov cables hloov tau yooj yim, cov neeg siv yuav tsum xav txog ntau yam tseem ceeb.

Los ntawm txoj kev pom, qhov tshwj xeeb ntawm kev hloov pauv ntawm cov cables hloov pauv feem ntau yog los ntawm lawv cov qauv tsim tshwj xeeb.
