Ngubani owalithumele kwaye nini?
Iimbali zeengcamango kunye neengcamango zincinci njengoko zinomdla, kwaye kunzima ukukhomba kwindawo yokuqala. Nangona kunjalo, sikwazi ukuchonga i-imeyile yokuqala, kwaye siyazi ngokucacileyo malunga nokuba kwenzeka ntoni kwaye xa ithunyelwe.
Ukukhangela i-ARPANET
Ngowe-1971, i-ARPANET (i-Advanced Research Projects Agency Network) yayisanda kuqalisa ukuvela njengenethiwekhi yokuqala yokuqala yeekhomputha. Yayixhaswe kwaye yenziwe yiSebe lezoKhuseleko laseMelika kwaye iza kuqhuba ekuqhutyweni kwe-intanethi. Nangona kunjalo, ngowe-1971, i-ARPANET yayingekho iikhomputha ezincinci, kwaye abo babesazi malunga nayo bafuna ukusetyenziswa okukhoyo kwile mveliso.
URichard W. Watson wacinga ngendlela yokuhambisa imiyalezo kunye neefayile kubashicileli kwiindawo ezikude. Wafaka "iProtokholi yeposi yeProjekthi" njengowomgangatho osezantsi phantsi kwe-RFC 196, kodwa umgaqo-nkqubo awuzange usebenze. Ukujonga ingqalelo kwaye unike iingxaki zanamhlanje nge- imeyli engenamsebenzi kunye neifeksi ze-junk phambi koko, mhlawumbi akunjalo konke okubi.
Omnye umntu onomdla wokuthumela imiyalezo phakathi kweekhompyutheni nguRay Tomlinson. I-SNDMSG, inkqubo ekwazi ukuthumela imiyalezo komnye umntu kwikhompyutheni enye yayivele ibe malunga ne-10 iminyaka. Yanikezela le miyalezo ngokufaka kwifayili enomsebenzisi ofuna ukuyifumana. Ukufunda umyalezo, bamane bafunde ifayile.
I-SENDMSG & # 43; CPYNET & # 61; EMAIL
Ngokuqinisekileyo, uTomlinson wayesebenza kwiqela kwiBBN Technologies eyaphuhlisa inkqubo yokudlulisa iifayile eyi-CPYNET, engabhala nokufunda iifayile kwikhomputha ekude.
U-Tomlinson wenza iPCYNET ifake kwiifayile endaweni yokufaka endaweni yazo. Emva koko wadibanisa ukusebenza kwayo kunye ne-SENDMSG ukuze ikwazi ukuthumela imiyalezo kumashishini asele. Iprogram yokuqala ye-imeyile yazalwa.
I-imeyile yokuqala ye-imeyile yomyalezo
Emva kwemiyalezo embalwa yokuvavanya equkethe amagama angapheliyo "QUERTYIOP" kwaye mhlawumbi "ASDFGHJK," uRay Tomlinson unelisekile ngokwaneleyo ngokubonakalisa kwayo yonke into yeqela.
Ngethuba ekuhambiseni intetho kwindlela ifomu kunye nomxholo ongenakulinganiswa ngayo, uTomlinson wathumela i-imeyili yokuqala yangempela ngasekupheleni kuka-1971. I-imeyile yazisa ukuba khona kwayo, nangona amagama asemthethweni sele akhohliwe. Nangona kunjalo, kwaziwa ukuba yayiquka imiyalelo malunga nendlela yokusebenzisa i-@ impawu kumakheli e- imeyile .
