Isidingo se-Awa "Embonini Yezokuxhumana" - CISCO

Imbonini ye-IT ibe ukuma phakathi kwezinhlobo eziningi emva kwembonini ngenxa yezinhle zayo kuze kube sekubizweni, izinkokhelo, ukubheka kanye nokuphikiswa okunakho. Isidingo sezimo zokuhlala, ukuthuthukisa nokuthuthukiswa kwebhizinisi le-IT senze umqondo wokuthi "Ukuxhumana" nokuthuthukiswa okusheshayo, futhi ukuqhubeka "ku-Networking" kuye kwaveza "ochwepheshe" kule nkambu. Ngesithakazelo esikhulu salezi zinkampani futhi sithuthukisa ukufinyeleleka kwabo okulula nokukhuphuka, intshisekelo yokuba "AbaPhezulu Abalungisiwe" baye bahlakulela. Namuhla, ngisho nokufinyeleleka kwe-"Professional Professionals" akuyona yonke into enzima, futhi isidingo sokubaluleka okukhulu sishintshele ku "Abaqeqeshi Abaqinisekisile" abaqinisekisiwe kwezinye izingxenyekazi zekhompyutha, izinqubo, nokusebenza. Ukuvuma kwalaba "Abakwa-Affirmed Professionals" kungenxa yendlela abayilungisile ngayo noma abaqinisekisile ekunqumeni, ama-commonsense nezinhlelo zamuva zokuxhumana ezihlobene nemakethe. Ukuhlonishwa ngokujulile kwalaba "Abasebenzi Abaqinisekisiwe" yibo abaqinisekiswa ku-"CISCO" .. !!

Kungani isitifiketi se-CISCO sihle kakhulu "Sokuhlonipha"?

I-CISCO iyinkosi ye-"Networking Industry" futhi uma kungenzeka ukuthi uqinisekisiwe noma unikezwe ngumbusi ngokucacile uphenduka "Amadoda eNkosi". Zonke izinto ezicatshangwayo, lokhu kungesizathu esisodwa kodwa iqiniso ukuthi ochwepheshe abaqinisekisiwe be-CISCO banokuqonda okuphakeme kakhulu kunethiwekhi ye-intanethi, izinto, amanethiwekhi ahlukahlukene ahlangene ndawonye endaweni futhi ngendlela, iningi lezinto ezihlanganisa imboni, isimiso samanje sezinto eziphilayo emhlabeni wonke, sisuka ku-CISCO. Namuhla i-CISCO iyiphayona elimangalisayo, elingenakuphikiswa, eliphelele ebhizinisini lokuxhumana. Inikeza izimpendulo ngamaklayenti egajethi ahlanganisiwe kumanethiwekhi ahlukahlukene ukuze ahlangane ngokungenakuqhathaniswa, enza ukufinyeleleka kanye nokushintshaniswa kwedatha phakathi kwabantu abalula, kungakhathaliseki ukuthi yiziphi izinhlobo ngesikhathi, indawo nezigaba. I-CISCO idlulisela izinqumo zokuxhumana ezinqunyelwe ukuphela kokugcina, okwenza isakhiwo esivamile sinikeze ukulawulwa kwenethiwekhi okungabonakali. Ibuye inikeze nezinhlobonhlobo ezihlukahlukene zezinto zokusebenza ukuze kuqinisekiswe yi-Cisco Internetwork Operating System Software. Yingaleso sizathu ukuqhubela phambili kanye nokuhlangana kubandakanya isithakazelo sochwepheshe oqinisekiswa yi-CISCO okusho ukuthi "i-CCNA Certification". Ukuqeqeshwa kwe-"Cisco Certified Network Associate" kuyimpendulo yanamuhla yokunikeza ukuqhutshwa kwesimiso sakho sokuxhumana.

IziKronikeCISCO

Kuyathakazelisa kakhulu ukuphenya ukuthi kanjani futhi nini i-CISCO yaba namandla amakhulu kakhulu ebhizinisini lokuxhumana. Ibuyela emuva ku-1980 lapho uLen Bosack noSandy Bosack, bobabili basebenza emahhovisi e-PC e-Stanford University benza isiphakeli lapho ama-PC abo angakhulumisana khona esebenzisa umhlangano we-IP. Ku-1984 basungula "izinhlelo ze-cisco" futhi kamuva ku-1992 igama laguqulwa libe yi "CISCO Systems, Inc.". Ngaleso sikhathi benza ambalwa "Amaseva E-Portal" okwamanje okubizwa ngokuthi "i-Old Alphabet Soup Products" njenge - AGS; I-MGS; I-CGS; I-IGS ne-AGS +. Ngaphakathi konyaka i-CISCO idlulisele ukushintshwa kwe-4000 okumangalisayo, i-7000, i-2000, nokushintshwa kwe-3000. Kungakapheli iCISCO ende yaphenduka inhlangano eyayikuthanda kakhulu futhi edingekayo ekhethekile ebhizinisini lokuxhumana. Lokhu kwaveza olunye uhlobo lokuvivinya kubo, okuyindlela yokubheka kuzo emazingeni ahlukene nasezindaweni ezihlukahlukene. Ukuba nezinsimbi eziyinkimbinkimbi namalungiselelo afuna abasebenzi abanekhono ukuletha, ukuwahlola nokuwahlola. Impendulo efanelekile yafika njengohlelo lwe-Cisco Certified Internetwork Expert (CCIE). Inhloso yayiyisisekelo kakhulu - inani eliningi lemishini edingekayo edingekayo ochwepheshe abanolwazi abangenza okufanayo naphezu kokuqapha nokuphenya lapho kudingeka. Lolu hlelo lwalungisa ochwepheshe abangathatha kuzo zonke lezi futhi benze njengoba kudingeka. Lolu hlelo lwaluqinisekisa abantu emazingeni ahlukene okukwazi ukusebenza okukhethekile, ukulawulwa kwezinhlelo zokuxhumana kanye nokwenza izinyathelo ngenxa yokuvulwa kwabo bonke, okwakukade kuvinjelwe umbhangqwana. I "CCNA isitifiketi" yisinyathelo sokuqala noma ungayibiza ngokuthi "itshe lokungena" kulolu hlelo.

CCNA Certification noma CCNA Training

I-CCNA Certification yisitifiketi sokugunyazwa kunoma yimuphi umqeqeshi wezinethiwekhi odingeka ukuthi abe ngu-CISCO oqinisekisiwe. Zonke ezinye izitifiketi zithatha lesi saziso esiyisisekelo. Izinzuzo zokuba yi-CCNA Certified / Certification ziningi, ukubhala uhlu oluthile -
