Isithelezi

Isithelezi (noma ihlelokusebenza elisithelezi ), luyinhleleliso yesicikizi esetshenziselwa ukutheleza, ukuhlonga, nokuhlanza uhlelo oluyingozi.

Uhlelo lwesithelezi ngokwendabuko yasungulwa ukuze ihlonge futhi ihlanze amagciwanyani esicikizi, ingakho kuthiwa isithelezi. Nokho, ngokwanda kolunye uhlelo oluyingozi, isithelezi saqala ukuvika ezinye izinsongo zesicikizi. Eminye imikhiqizo ihlanganisa nokulonda isicikizi kuma -URL ayingozi, ugaxekile kanye nokuyenga.

 Inkathi yowe-1971–1980 (eyandulela isithelezi) 
Igciwanyani lokuqala elaziwayo lesicikizi lavela ngowe-1971 futhi lalibizwa ngokuthi Creeper virus. Leli gciwanyani lalihlasela izicikizikhulu zohlobo le-DEC PDP-10 ezazigununda ihlelomgidingo TENEX.From the first email to the first YouTube video: a definitive internet history . Tom Meltzer and Sarah Phillips. The Guardian. October 23, 2009IEEE Annals of the History of Computing, Volumes 27–28. IEEE Computer Society, 2005. 74 : "[...]from one machine to another led to experimentation with the Creeper program, which became the world's first computer worm: a computation that used the network to recreate itself on another node, and spread from node to node."

Ngokuhamba kwesikhathi igciwanyani Creeper lasuswa inhleleliso ebizwa Reaper eyakhandwa nguRay Tomlinson. Abanye abantu bathatha leyonhleleliso njengohlelo lesithelezi lokuqala olwalotshwa -- noma kunjalo, Kodwa kumqoka ukuveza ukuthi leyonhleleliso ebizwa Reaper nayo kwakuyigciwanyani eliklanyelwe ukususa igciwanyani Creeper.

Igciwanyani Creeper lalandelwa amanye amagciwanyani amaningana. Elinye elaziwayo elavela lalibizwa Elk Cloner, ngonyaka we-1981, futhi lalihlasela izicikizi zohlobo lwe-Apple II.
