Ubuchwepheshe Bokuthunyelwa Kwabagibeli Nge-inthanethi Esheshayo
Esikhathini lapho ukuxhumana sekuyinto edingekayo nsuku zonke, imikhumbi yabagibeli ayiseyona nje indlela yokuhamba ethatha abantu besuka kwelinye ichweba beya kwelinye. Imikhumbi yesimanje isiphenduke izindawo zokuhlala zesikhashana: izindawo zokusebenza kude, ukujabulela ukuzijabulisa kwedijithali, ukwenza izingcingo zevidiyo nomndeni, ngisho nokuphatha izindaba zebhizinisi. Ngakho-ke, i-inthanethi esheshayo emikhunjini yabagibeli manje ibhekwa njengento ebalulekile, kanye nokuphepha, induduzo yegumbi, kanye nezinsizakalo zokudla nezokuzijabulisa. Umbuzo uwukuthi: imikhumbi ekude kangaka nomhlaba inganikeza kanjani i-inthanethi esheshayo nezinzile? Impendulo ilele ekuhlanganisweni kobuchwepheshe besathelayithi besizukulwane esilandelayo, amanethiwekhi emikhumbi yangaphakathi ayinkimbinkimbi, kanye nezinhlelo zokuphatha i-bandwidth ezihlakaniphile.
Kungani i-inthanethi esheshayo emikhunjini iyimfuneko?
Isidingo se-inthanethi emikhunjini yabagibeli siyakhula kanye nokushintsha kokuziphatha kwabasebenzisi. Abagibeli bafuna ukuhlala bexhumene nezinkundla zokuxhumana, basakaze umculo nama-movie, bafinyelele amamephu okuhamba, futhi benze imisebenzi esekelwe efwini. Kwabaqhubi bemikhumbi, ukuxhumana kusekela nemisebenzi ebalulekile yokusebenza: ukuqapha injini ngesikhathi sangempela, ukubika isimo sezulu, ukuxhumana ngechweba, izibuyekezo zemizila, izinhlelo zokuthengisa amathikithi, kanye nensizakalo yamakhasimende. I-inthanethi esheshayo ayiseyona nje into "engeziwe" ewusizo, kodwa iyingxenye yokuguqulwa kwedijithali kwemboni yezolwandle.
