Njengoko iinkqubo zokunxibelelana kwekhompyutha zephuhliso lwezobuchwepheshe, ezinye iicandelo kunye neenkokheli zezemfundo zazifunda imigaqo yazo kwaye zicebisa iingcamango ezahlukeneyo malunga nendlela abasebenza ngayo. Zininzi zale ngcamango zimi vavanyo lwangethuba (ezinye zide kakhulu kunabanye) kwaye zaguqukela "kwimithetho" esemthethweni abaphandi abathandekayo abayifumene emsebenzini wabo. Imigaqo engezantsi iye yavela njengeyona nto ifanelekileyo kwintsimi ye-intanethi.
Umthetho weSarnoff
UDavid Sarnoff wathuthela eUnited States ngowe-1900 waza waba ngumbutho ovelele waseMerika kwirediyo kunye nomabonwakude. UMthetho we-Sarnoff uthi ubuncwane bemali yomnatha wobhengezo bunxulumene ngqo nombolo yabantu abasebenzisayo. Le ngcamango yayiyiveli eminyakeni eyi-100 eyadlulayo xa iilgragraphi kunye namayeza okuqala asetyenziswa ukuthumela imiyalezo evela komnye umntu ukuya kwenye. Nangona lo mthetho ungasetyenziswa ngokubanzi kumanethiwekhi ekhompyutheni yanamhlanje, kwakungenye yezinto zokuqala ezisisiseko zokucinga ukuba ezinye iintuthuko zakhiwe.
Umthetho waseShannon
UClaude Shannon wayengumatemati oye wagqiba umsebenzi wokuqhaqhaqhafaza kwintsimi ye-cryptography kwaye wasungula intsimi yenkcazelo yenkcazelo apho ubuninzi beetheknoloji yonxibelelwano yedijithali esekelwe. Ukuphuhliswa kwiminyaka ye-1940, uMthetho we-Shannon ngumgaqo wemathematika uchaza ubudlelwane phakathi (a) nomlinganiselo wesantya-ntlawulo esingekho mpazamo yoqhagamshelwano, (b) nomda wokuhamba kunye kunye (c) nomlinganiselo we-SNR (isilinganiso somsindo-ngxolo):
= = b * log2 (1 + c)
UMthetho kaMetcalfe
URobert Metcalfe wayengumqambi we- Ethernet . UMthetho weMetcalfe uthi "ukubaluleka kwenethiwekhi kunyuka ngokuthe ngqo ngeenombolo." Okokuqala wakhulelwa malunga no-1980 kwimeko yokuphuhliswa kwexesha le-Ethernet, uMthetho kaMetcalfe waziwa ngokubanzi kwaye wasetyenzwa ngexesha le-intanethi ye-1990.
Lo mthetho uvame ukugqithisa ukubaluleka kwoshishini elikhulu okanye inethiwekhi yomntu (ikakhulukazi i-intanethi) kuba ayithathi ingqalelo imodeli yokusetyenziswa yabantu abaninzi. Kwiinkonzo ezinkulu, abasebenzisi abancinci kunye neendawo zivame ukuvelisa ininzi yesithuthi (kunye nexabiso elihambelanayo). Abaninzi baye bathetha ukuguqulwa koMthetho kaMetcalfe ukukunceda ukuhlawula le mpawu yemvelo.
Umthetho weGilder
Umbhali uGeorge Gilder wapapasha incwadi yakhe yeTelecosm: Yeka indlela i-Infinite Bandwidth eya kuguqula ngayo ihlabathi lethu ngonyaka ka-2000 . Kule ncwadi, i-Gilder's Law ithi "i-bandwidth ikhula ubuncinane kathathu ngokukhawuleza kunamandla ekhompyutheni." UGilder ubizwa ngokuba ngumntu ogama lomthetho kaMetcalfe ngo-1993 kwaye wancedisa ukwandisa ukusebenzisa kwawo.
UMthetho weReed
UDavid P. Reed ngumfundi wekhompyutheni ophumelele ekuphuhlisweni kweTCP / IP kunye ne- UDP . Ishicilelwe ngo-2001, uMthetho weReded uthi ukusetyenziswa kwezixhobo ezininzi kunokwenziwa ngokukhawuleza ngobukhulu benethiwekhi. I-Reed ithi apha ukuba umthetho kaMetcalfe uhlawula ixabiso lentengiso njengoko likhula.
UMthetho kaBikekstrom
U-Rod Beckstrom ngumlingisi wobugcisa. Umthetho we-Beckstrom waboniswa kwiinkomfa zengqungquthela zokhuseleko lwenethiwekhi ngo-2009. Uthi "ixabiso lentengiso lilingana nexabiso lentengo elongezelelweyo kumsebenzi ngamnye womsebenzisi oqhutyelwa ngolu hlobo lwenethiwekhi, oluxabiswa kumbono ngamnye womsebenzisi, kwaye lushwankathele bonke." Lo mthetho uzama ukuphucula amanxibelelwano enzentlalo apho uluncedo aluxhomeki kuphela kubukhulu njengomthetho kaMetcalfe kodwa kunye nokusetyenziswa kwexesha elichithwe ngokusebenzisa inethwekhi.
UMthetho kaNacchio
UJoseph Nacchio nguye owayengumlawuli wezoshishino zangaphambili. Umthetho ka-Nacchio uthi "inani lamagalelo kunye nexabiso ngalinye kwisango le-IP liphucula ngeendlela ezimbini zokuba zikhulu zonke iinyanga ezili-18."
