URobert Metcalfe waba namuphi umthelela emphakathini?
Context:Ngenkathi ephishekela iziqu zakhe zobudokotela kwezesayensi yamakhompyutha, uMetcalfe wathatha umsebenzi ngeProject MAC ye-MIT ngemuva kokuthi iHarvard yenqabe imvume yokuthi axhume inyuvesi kwi-ARPAnet entsha ngaleso sikhathi. E-MAC, uMetcalfe wayephethe ukwakha ezinye zezinto ezaziyoxhuma ama-minicomputer e-MIT ne-ARPAnet. UMetcalfe wenza i-ARPAnet yaba isihloko somsebenzi wakhe wokuphothula iziqu, kodwa ekuqaleni iHarvard yawenqaba. UMetcalfe wanquma indlela yokuthuthukisa iziqu zakhe ngesikhathi esebenza e-Xerox PARC, lapho afunda khona iphepha mayelana nenethiwekhi ye-ALOHA eNyuvesi yaseHawaii. Wakhomba futhi walungisa amanye amaphutha kumodeli ye-AlohaNet, wabe esenezela lowo msebenzi esifundweni sakhe esibukeziwe. Yabe isamukelwa yiHarvard, eyamnika iziqu zobudokotela.  UMetcalfe wayesebenza e-PARC ngo-1973 lapho yena noDavid Boggs basungula i-Ethernet, ekuqaleni njengezinga lokuxhuma amakhompyutha emabangeni amafushane. Kamuva wakhumbula ukuthi i-Ethernet yazalwa ngoMeyi 22, 1973, usuku asakaza ngalo imemo enesihloko esithi "Alto Ethernet" eyayiqukethe i-schematic enzima yokuthi izosebenza kanjani. "Yileso isikhathi sokuqala i-Ethernet ivela njengegama, njengoba kwenza umqondo wokusebenzisa i-coax njenge-ether, lapho iziteshi ezihlanganyelayo, njenge-AlohaNet noma i-ARPAnet, zizofaka amaphakethe wazo wedatha, zizohamba nge-megabits ngomzuzwana, kuzoba nokushayisana, nokudluliswa kabusha, nokubuyela emuva", kuchaza uMetcalfe. UBoggs wagomela ngokuthi olunye usuku kwakuwukuzalwa kwe-Ethernet: ngoNovemba 11, 1973, usuku lokuqala uhlelo lwasebenza ngempela.  Ngo-1979, uMetcalfe washiya i-PARC futhi wasungula i-3Com, umkhiqizi wemishini yokuxhumana ngamakhompyutha, efulethini lakhe ePalo Alto. I-3Com yaba umhlinzeki oholayo wezixazululo zenethiwekhi, kanti i-Ethernet yaba yiyona ndlela yokuxhumana eyinhloko yamanethiwekhi endawo (ama-LAN). Ngo-1980 wathola i-ACM Grace Hopper Award ngeminikelo yakhe ekuthuthukiseni amanethiwekhi endawo, ikakhulukazi i-Ethernet. Ngo-1990, ibhodi yabaqondisi be-3Com yamisa u-Éric Benhamou njengo-CEO esikhundleni sikaMetcalfe, owashiya inkampani. Wachitha iminyaka eyishumi njengomshicileli nomhlaziyi, ebhala ikholomu ye-Internet ye-InfoWorld. Ngo-1996, wasungula iPop!Tech, ingqungquthela yezobuchwepheshe ephezulu. Waba ngumtshali-zimali we-venture ngo-2001 futhi kamuva waba ngumlingani jikelele ePolaris Venture Partners.  Kusukela ngo-2011 kuya ku-2021 wayenguprofesa e-University of Texas e-Austin's Cockrell School of Engineering, egxile ezinhlelweni zokuqamba izinto ezintsha. UMetcalfe wayeyisikhulumi esivelele kwi-2016 Congress of Future Science and Technology Leaders kwathi ngo-2019 wethula iBernard Price Memorial Lecture eNingizimu Afrika. NgoJuni 2022, uMetcalfe wabuyela eMIT ngokujoyina iComputer Science and Artificial Intelligence Laboratory njengenhlangano yocwaningo kanye nonjiniyela wokubala, esebenza ne-MIT Julia Lab.
URobert Metcalfe wayengusomabhizinisi ophumelelayo, owayesungule izinkampani ezinjenge-3Com nePop!Tech. Wayephinde abe uprofesa e-University of Texas nomcwaningi eMassachusetts Institute of Technology. Nokho, umnikelo wakhe omkhulu kunayo yonke kwaba ukusungulwa kwe-Ethernet ngo-1973. Lokhu kwaba indinganiso yokuxhumeka kwe-Internet ngentambo, okusasetshenziswa eminyakeni engu-50 kamuva.
