Ubani othumele futhi nini?
Imininingwana yemibono nemibono yinkimbinkimbi njengoba iyancipha, futhi ngokuvamile kunzima ukukhomba umlando wokuqala. Kodwa-ke, sikwazi ukubona i-imeyili yokuqala, futhi siyazi kancane ukuthi kwenzeka kanjani futhi uma ithunyelwe.
Kusesha Ukusetshenziswa kwe-ARPANET
Ngo-1971, i-ARPANET (Advanced Research Projects Agency Network) yayisanda kuqalisa ukuvela njengenethiwekhi enkulu yokuqala yamakhompiyutha. Yayixhasiwe futhi yenziwa nguMnyango Wezokuvikela wase-United States futhi kamuva izoholela ekuthuthukiseni i-intanethi. Kodwa-ke, ngo-1971, i-ARPANET yayingekho amakhompiyutha axhunyiwe, futhi labo ababazi ngakho bafuna ukusetshenziswa okungenzeka kwalolu hlelo.
URichard W. Watson wacabanga ngendlela yokuhambisa imiyalezo namafayela kubashicileli kumasayithi akude. Ufake "I-Protocol Box Protocol" yakhe njengezinga elilinganiselwe ngaphansi kwe-RFC 196, kodwa le protocol ayizange isebenze. Ngokucabangela futhi kunikezwe izinkinga zanamuhla nge- imeyili engenamsebenzi kanye nefeksi engafani ngaphambi kwalokho, cishe akuyona yonke into embi.
Omunye umuntu onentshisekelo yokuthumela imiyalezo phakathi kwamakhompyutha kwakunguRay Tomlinson. I-SNDMSG, uhlelo olungahle lunikeze imilayezo komunye umuntu kumakhomphyutha afanayo luye lwaba cishe iminyaka eyishumi. Ihambise le milayezo ngokufaka ifayela efayili yomsebenzisi ofuna ukuyifinyelela. Ukuze ufunde umyalezo, bamane bafunde ifayela.
I-SENDMSG & # 43; I-CPYNET & # 61; EMAIL
Ngokusobala, uTomlinson wayesebenza eqenjini ku-BBN Technologies eyakha uhlelo lokuhlola ifayela oluhlolwayo olubizwa nge-CPYNET, elingabhala futhi lifunde amafayela kumakhompuyutha akude.
U-Tomlinson wenza i-CPYNET ijoyine kumafayela kunokufaka esikhundleni sayo. Wabe esehlanganisa ukusebenza kwayo nalokho kwe-SENDMSG ukuze ithumele imilayezo kumishini esilawuliwe. Uhlelo lokuqala lwe-imeyili lwazalwa.
Umlayezo we-imeyli we-First First Network
Ngemuva kwemiyalezo embalwa yokuhlola equkethe amagama angaphelelwa yisikhathi "QUERTYIOP" futhi mhlawumbe "ASDFGHJK," uRay Tomlinson wanelisekile ngokusungulwa kwakhe ukuze abonise kulo lonke iqembu.
Ngenkathi ehambisa isethulo ngendlela ifomu nokuqukethwe okungenakuhlukaniswa ngayo, uTomlinson wathumela i-imeyili yokuqala yangempela ngasekupheleni kuka-1971. I-imeyili yamemezela ukuba khona kwayo, nakuba amagama aqondile ekhohliwe. Kodwa-ke, kwaziwa ukuthi yayihlanganisa imiyalo yokuthi ungasebenzisa kanjani @ umlingiswa kumakheli e- imeyili .
