Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Muna 1977, Berkeley Software Distribution (BSD) yakagadzirwa neComputer Systems Research Group (CSRG) kubva kuUC Berkeley, yakavakirwa pa6th edition yeUnix kubva kuAT & T. Sezvo BSD yaive neUnix kodhi yaive yeAT & T, AT & T yakamhan'ara mhosva (USL v. BSDi) mukutanga kwema1990 vachipesana neYunivhesiti yeCalifornia. Ikoku kwakaganhurira zvakasimba kukura nokugamuchirwa kweBSD. Muna 1983, Richard Stallman akatanga chirongwa cheGNU nechinangwa chokusika hurongwa hwekushandisa husina rusununguko hwakafanana neUNIX. Sechikamu chebasa iri, akanyora GNU General Public License (GPL). Pakutanga kwema1990, kwakanga kwava nesoftware inenge yakakwana yokugadzira hurongwa hwekushandisa hwakakwana. Zvisinei, kernel yeGNU, yainzi Hurd, yakatadza kukwezva nhamburiko dzakakwana dzokuvandudza, ichisiya GNU isina kukwana. Muna 1985, Intel yakabudisa 80386, yekutanga x86 microprocessor ine 32-bit mirayiridzo yakagadzirirwa uye chikwata chekugadzirisa chiyeuchidzo nepeji. Muna 1986, Maurice J. Bach, weAT & T Bell Labs, akabudisa The Design of the UNIX Operating System. Tsananguro iyi yokupedzisira ainyanya akafukidza System V Release 2 tsinga, pamwe zvimwe zvitsva kubva Release 3 uye BSD.  Mubvunzo: Mapurogiramu epurogiramu akawanda sei akanga aripo pakuvamba kwema1990?
