I-AppleTalk Yayiyisistimu Yenethiwekhi Yokuqala ye-Mac
Kusukela ekusungulweni kwe-Mac ngo-1984, i-Apple ihlanganise ukusekelwa kwenethiwekhi okuzakhelwe ngaphakathi. Namuhla, i- Ethernet port noma i- Wi-Fi eyakhiwe akulindeleke kuphela kodwa ibuye ibe yinto engavamile. Kodwa ngonyaka ka-1984, ukuba nekhompiyutha enezinhlelo zokuxhumana ezakhelwe ngaphakathi kwakuyinto eguquguqukayo.
I-Apple ekuqaleni yasebenzisa uhlelo lokuxhumana olubizwa nge-AppleTalk, oluvumela lawo ma-Macs akuqala ukuba axoxisane kuphela kodwa okubaluleke nakakhulu, ukwabelana ngaleso sikhathi, okwakukhona ngaleso sikhathi, izinhlelo zokuphrinta ze-laser ezibiza kakhulu. Lawa maphrinta ayingxenye yempikiswano yokushicilela ideskithophu ama-Macs asekuqaleni afakwe kuwo.
Ukuze uqonde ukubaluleka kwe-AppleTalk, futhi kamuva, i-EtherTalk, izinhlelo ezazisetshenziswa yi-Apple, kufanele uphinde ubuye ubone ukuthi yiluphi uhlobo lwamanethiwekhi atholakala ngo-1984.
I-Network Like It & # 39; s 1984
Ngo-1984, okungenani njengoba ngikhumbula, kwakunezinhlelo ezimbalwa zezinethiwekhi ezahlukene ezikhona. Cishe konke kwakunikezwa njengama-add-in amakhadi kuzilungiselelo zekhompyutha ngaleso sikhathi. Amakhulu amathathu ngaleso sikhathi ayeyi- Ethernet , i- Token Ring , ne-ARCNET. Ngisho nokuthi kunezinhlelo ezintathu zokuxhuma kwenethiwekhi empeleni iselulela iphuzu. Kwakukhona izinguqulo ezihlukahlukene zenethiwekhi ngayinye, ngezinhlayiyana ezahlukene zokuxhumana kanye nemidiya yokuxhumana ephathekayo esetshenzisiwe, futhi yiyo kuphela izinhlelo ezinkulu zenethiwekhi ezintathu; kwakukhona ezinye izinhlelo ezimbalwa ongakhetha kuzo.
Iphuzu lokuthi, ukukhetha inethiwekhi yezinhlelo zakho zekhompyutha kwakungeyona into encane, futhi uma ukhethe inethiwekhi, kwakukhona umsebenzi omningi ozokwenza ukusetha, ukulungisa, ukuhlola, ukuhambisa, nokuphatha uhlelo lwenethiwekhi.
I-AppleBus
Phakathi nokuthuthukiswa kokuqala kwe-Mac yokuqala, i-Apple yayifuna indlela yokuvumela i-Macintosh ne-Lisa amakhompiyutha ukuthi abelane ngephrinta ye-LaserWriter, yona eyedwa, ibiza ngokulingana ne-Macintosh ka-1984. Ngenxa yendleko ephezulu yalesi sakhiwo, kusobala ukuthi imithombo yokunyathelisa kwadingeka yabelwe.
Ngaleso sikhathi, i-IBM yayivele ibonise inethiwekhi yayo ye-Token Ring futhi yayilindele ukwenza ubuchwepheshe bube khona ekuqaleni kuka-1983. IBM yayiphuzile ekukhipheni inethiwekhi ye-Token Ring, iphoqa i-Apple ukuba ibuke kwisisombululo senethiwekhi yesikhashana.
I-Mac emuva ngaleso sikhathi yasebenzisa i-chip control controller ukuze inakekele amarekhodi ayo angama-serial. Lesi chiphu se-controller serial sinezakhiwo ezithile ezingavamile, kufaka phakathi isivinini esisheshayo, kufika ku-256 kilobits ngomzuzwana, futhi ikhono lokuba nesitoreji se-protocol yenethiwekhi esakhiwe ku-chip ngokwazo. Ngokwengeza ezinye zezifunda ezengeziwe, i-Apple yakwazi ukusunduza ijubane cishe ngamakhilogremu angu-500 ngomzuzwana.
Ngokusebenzisa le nsiza yesilawuli se-serial, i-Apple yakwazi ukwakha uhlelo lwenethiwekhi noma yimuphi umsebenzisi angasetha; akudingeki isizinda sobuchwepheshe. Kwakunezidingo zokuhlela zero; ungakwazi empeleni ukuxhuma ama-Macs kanye nezinsimbi, ngaphandle kwesidingo sokunikeza amakheli noma ukusetha isiphakeli.
I-Apple ibize le nethiwekhi entsha i-AppleBus, futhi yayihlanganisa ne-Lisa computer kanye no-1984 Macintosh, kanye ne-adapters ezingasetshenziswa kuma-computer we-Apple II ne-Apple III.
AppleTalk
Ezinyangeni zakuqala zika-1985, uhlelo lwe-IBM lwe-Token Ring aluzange luhanjiswe, futhi i-Apple yanquma ukuthi inethiwekhi ye-AppleBus ingahlangabezana nezidingo zabasebenzisi bayo ngenkathi inikeza uhlelo lokusetha kwenethiwekhi nenethiwekhi. Eqinisweni, noma ubani angakha inethiwekhi nama-macs ambalwa, i-LaserWriter, kanye nesistimu ye-AppleBus.
Ngokukhululwa kwe-Macintosh Plus ngo-1985, i-Apple iqamba kabusha i-AppleBus ku-AppleTalk futhi yanezela ukuthuthukiswa okumbalwa. Iba nesivinini esiphezulu samakhilogremu angaphansi kuka-500 ngomzuzwana, ibanga elingamamitha angu-1 000, nomkhawulo wamadivayisi angu-255 axhunywe kwinethiwekhi ye-AppleTalk.
Uhlelo lokuqala lwe-AppleTalk lokucubungula lwaluqeda futhi lusetshenziselwa ikhebula elilula le-conductor ezintathu. Okubaluleke nakakhulu, yilokho i-Apple eyashiya isendlalelo sangempela senethiwekhi futhi izinga lesofthiwe lihlukile . Lokhu kwavumela ukuba i-AppleTalk isetshenziswe phezu kwezinhlobo ezimbalwa zemidiya engokwemvelo, kuhlanganise nekhamera yase-AppleTalk yasekuqaleni etholakala ku-Apple, kodwa futhi ne-adapter ye-PhoneNet engabizi kakhulu, futhi elula kakhulu, eyasebenzisa i-cabling standard ye-conductor yocingo.
Ngo-1989, i-Apple yakhipha i-AppleTalk Phase II, eyasusa umkhawulo we-node yenethiwekhi engu-255 we-original version. I-Apple iphinde yengeze izinhlelo ze-EtherTalk neTokenTalk zenethiwekhi ezavumela i-Macs ukusebenzisa uhlelo olujwayelekile lwe-Ethernet manje, kanye namanethiwekhi we-IBM's Token Ring.
Ukuphela kwe-AppleTalk
I-AppleTalk isinde kakhulu esikhathini se- OS X sama-Macs . Lokhu kwakungenxa yesisekelo esikhulu esifakiwe sephrinta laser, namanethiwekhi amancane wendawo axhuma izingcosana zama-Macs ndawonye. Lapho i-Apple iqala i- OS X Snow Leopard ngonyaka ka-2009 , i-AppleTalk ishiyiwe ngokusemthethweni, futhi ayisekho emkhiqizo we-Apple.
I-AppleTalk & # 39; s Legacy
I-AppleTalk yayiyisistimu yenethiwekhi entsha yesikhathi sayo. Nakuba kwakungeyona eyasheshayo, ngokuqinisekile yayiyi-network elula yokufaka nokuphatha. Ngaphambi kokuba ezinye izinhlelo zenethiwekhi ziqale ukuthengisa umqondo we-adapter yenethiwekhi yokuhlela noma yokulawula izinhlelo zenethiwekhi, i-AppleTalk inesikhathi eside isifinyelele isimo esilula ukusebenzisa, esilungisa abanye abazama ukuyibeka manje.
