## Tarihi
Babban labarin: Tarihin Intanet

Intanet ta samo asali ne daga ARPANET, wanda gwamnatin Amurka ta ba da tallafi don tallafawa ayyuka a cikin gwamnati, a jami'o'i da dakunan gwaje-gwaje na bincike a Amurka, amma ya girma cikin lokaci har ya haɗa da yawancin manyan jami'o'i na duniya da kuma bincike na kamfanonin fasaha da yawa. Amfani da mafi yawan masu sauraro ya zo ne a cikin 1995 lokacin da aka ɗage hane-hane kan amfani da Intanet don ɗaukar zirga-zirgar kasuwanci.

A farkon zuwa tsakiyar 1980s, yawancin samun damar Intanet daga kwamfutoci na sirri ne da wuraren aiki kai tsaye da ke da alaƙa kai tsaye zuwa cibiyoyin sadarwar gida (LANs) ko kuma ta hanyar haɗin kai ta hanyar amfani da modem da layukan wayar analog. LANs yawanci ana sarrafa su a 10 Mbit/s yayin da adadin bayanan modem ya girma daga 1200 bit/s a farkon 1980s zuwa 56 kbit/s a ƙarshen 1990s. Da farko, an yi haɗin haɗin bugun kira daga tashoshi ko kwamfutocin da ke aiki da software na kwaikwayo zuwa ga sabar tasha akan LANs. Waɗannan haɗin bugun kira ba su goyi bayan amfani da ƙa'idodin Intanet na ƙarshe zuwa ƙarshe ba kuma sun ba da haɗin kai-zuwa-baki kawai. Gabatar da sabar hanyar sadarwa da ke tallafawa Serial Line Internet Protocol (SLIP) daga baya kuma ka'idar batu-zuwa-point (PPP) ta tsawaita ka'idojin Intanet kuma ya sanya cikakken kewayon sabis na Intanet don masu amfani da bugun kira; ko da yake a hankali, saboda ƙananan ƙimar bayanan da ake samu ta amfani da bugun kira.

Wani muhimmin abu a cikin saurin haɓakar saurin shiga Intanet shine ci gaba a fasahar MOSFET (MOS transistor). MOSFET da aka ƙirƙira a Bell Labs tsakanin 1955 da 1960 sakamakon binciken Frosch da Derick, shine tushen ginin hanyoyin sadarwar Intanet. Laser, asali da Charles H. Townes da Arthur Leonard Schawlow suka nuna a cikin 1960, an karbe shi don tsarin hasken haske na MOS a kusa da 1980, wanda ya haifar da haɓaka haɓakar bandwidth na Intanet. Ci gaba da sikelin MOSFET tun daga lokacin ya haifar da haɓaka bandwidth na kan layi a kowane watanni 18 (Dokar Edholm, wacce ke da alaƙa da dokar Moore), tare da bandwidth na hanyoyin sadarwar sadarwa suna tashi daga bits a sakan daya zuwa terabits a sakan daya.

Samun damar Intanet na Broadband, sau da yawa an rage shi zuwa kawai buɗaɗɗen, ana bayyana shi azaman "hanyar Intanet wanda koyaushe ke kunne, kuma yana sauri fiye da hanyar shigar da kiran waya na gargajiya" don haka yana rufe nau'ikan fasaha. Tushen waɗannan fasahohin Intanet na watsa shirye-shirye sune na haɗin MOS (CMOS) da'irori na dijital, ƙarfin saurin wanda aka haɓaka tare da sabbin dabarun ƙira. Ana yin haɗin haɗi ta hanyar sadarwa ta hanyar amfani da kwamfutar da aka gina a cikin damar sadarwar Ethernet, ko ta amfani da katin fadada NIC.
