YeziKronikeCISCO

Kuyathakazelisa kakhulu ukuphanda indlela kunye nexa i-CISCO yavela njani ukuba yinto enamandla kakhulu kwi-intanethi. Ibuyela emuva kwi-1980 xa uLen Bosack noSandy Bosack, bobabini basebenza kwiiofisi ze-PC eziqhelekileyo kwiYunivesithi yaseStanford benza umncedisi apho ii-PC zabo zikwazi ukuthetha omnye nomnye usebenzisa i-intlanganiso ye-IP. Kwi-1984 baqulunqa "iinkqubo zeCisco" kwaye kamva kwi-1992 igama latshintshelwe "kwiCISCO Systems, Inc.". Ngelo xesha benza ambalwa "AbaSebenzi bePortal" namhlanje ebizwa ngokuthi "i-Old Alphabet Soup Products" njenge - AGS; MGS; CGS; IGS kunye ne-AGS +. Ngaphakathi konyaka i-CISCO ibonise ukutshintsha kwe-4000, 7000, 2000, kunye ne-3000 yokutshintsha. Ngaphambi kokuba i-CISCO ingakaphenduli ibe yintlangano enomdla kakhulu kwaye ifuna inzululwazi yezobuchwepheshe kwiinkampani zokunxibelelana. Oko kwavelisa olunye uhlobo lokuvavanya kubo, zeziphi iindlela zokubakhokela kuzo kumanqanaba athile kunye neendawo. Ukuba nezixhobo ezinzima kunye namalungiselelo afuna abasebenzi abanolwazi ukuzisa, ukujongana nokuphanda. Impendulo efanelekileyo yafika - i-Cisco Certified Workwork Expert (CCIE) program. Injongo yayisisiseko - inani elongezelelweyo lezixhobo eziza kuqaliswa zifunyaniswe iingcali ezinolwazi ezinokuthi zenze okufanayo ngaphandle kokunyamekela nokuphanda xa zifunwa. Le nkqubo ilungiselele iingcali eziza kuthatha zonke ezi zinto kwaye ziyenze njengoko zifunwa. Inkqubo yaqinisekisa abantu kumanqanaba ahlukeneyo okukwazi ukulawula, ukucwangciswa kwezicwangciso zokunxibelelana kunye nokukhuthaza ngokulandela iindlela zokuvula kubo bonke, okwakunyanzelekile ukuba kubekho isibini. "I-CCNA isitifiketi" yinyathelo lokuqala okanye ungabiza ngokuthi "ilitye lokungena" kweli lungiselelo.
