Sonke sizwile ngesoftware yamahhala noma umthombo ovulekile (umthombo ovulekile), kepha abantu abaningi abazi ukubaluleka kokuqonda umehluko phakathi kwale migomo. Ezindaweni okungezona ezekhompuyutha, le mibono ayizwakali kaningi kepha ikhona osukwini lwabo lwanamuhla ngoba ithinta izinhlelo zanoma iyiphi idivayisi ye-elekthronikhi, njengekhompyutha, ithebhulethi noma i-Smartphone.
Isofthiwe yobunini ivikela kuphela izintshisekelo zenkampani eyimakethayo futhi ayikwazi ukuguqulwa ngabantu bangaphandle ukuze ihlangabezane nezidingo ezithile . Ngokuphambene nalokho, isofthiwe yamahhala noma yomthombo ovulekile iyatholakala kuwo wonke umuntu futhi ingashintshwa ukuze ihlangabezane nezidingo zomuntu ngamunye.
Uhlelo lungabhekwa njengesoftware yamahhala uma ihlonipha inkululeko emine ebalulekile:
- Inkululeko 0: ikuvumela ukuthi usebenzise uhlelo noma ngabe ufuna kanjani.
- Inkululeko 1: ungafunda ikhodi yomthombo yalolu hlelo futhi ukhululekile ukuyiguqula, ngomqondo wokuthi ingenza noma yiziphi izinyathelo ezidingekayo.
- Inkululeko 2: ikuvumela ukuthi wenze futhi usakaze amakhophi alolo hlelo noma kunini lapho ufuna khona futhi ngaleyo ndlela usize abanye.
- Inkululeko 3: unganikela emphakathini, kalula ngokwenza noma ukusabalalisa amakhophi ngezinguqulo zakho eziguquliwe zohlelo.
Ngokusho kukaRichard Stallman, umsunguli we-Free Software Movement, “ lezi nkululeko zibaluleke kakhulu, hhayi nje kuphela ngenxa yenzuzo yomsebenzisi kodwa nangomphakathi wonke, njengoba zikhuthaza ubumbano . Ukubaluleka kwazo kuyanda njengoba isiko lethu nemisebenzi yansuku zonke ihlanganiswa kakhulu nomhlaba wedijithali.”
Ezikoleni, ukuba nesofthiwe yamahhala kuyinzuzo engenakuqhathaniswa ngoba kuzivumela ukuthi zonge imali ngokungakhokhi amalayisense okusebenzisa isofthiwe eyimfihlo. Ukulula kokukwazi ukufunda izinhlelo kubalulekile kulabo abafuna ukufunda ukuhlela, njengoba ukufunda ikhodi yabanye abantu kungasetshenziswa ekufundeni noma ekuxazululeni izinkinga.
Igama elithi "umthombo ovulekile " lavela ukuze kugwenywe ukungaqondi kahle okungenzeka ngomqondo " wesofthiwe yamahhala ." NgesiNgisi, leli gama lihunyushwa ngokuthi "mahhala," kodwa kulokhu, empeleni libhekisela enkululekweni yohlelo, hhayi entengo yalo.
Zonke isofthiwe yamahhala ziwumthombo ovulekile, kodwa akuzona zonke isofthiwe yomthombo ovulekile eziyisofthiwe yamahhala . Umehluko usezilayisensini ezingasetshenziswa kulolu hlelo: ezinye azinazo izimvume eziningi kunezinye futhi azibonisi inhlonipho enkulu ngenkululeko okukhulunywe ngayo ngenhla.
