Kulesi sihloko, sizohlola izici namandla ezilimi zokuhlanganisa. Sizothola ukuthi ivumela kanjani abahleli bezinhlelo ukuthi baxhumane ngqo nehardware yekhompuyutha, ukufinyelela amarejista, imiyalelo, namakheli enkumbulo. Nakuba kungase kubonakale kusabisa noma kuphelelwe yisikhathi uma kuqhathaniswa nezilimi zanamuhla ezisezingeni eliphezulu, isihlanganisi sisasetshenziswa ezimweni ezithile lapho kudingeka khona ukulawula okuphelele kokusebenza kwesistimu nezinsiza.
Luyini ulimi lomhlangano?
Ulimi lokuhlanganisa luwulimi lokuhlela olusezingeni eliphansi olusetshenziselwa ukubhala izinhlelo ezisebenza ngqo ekwakhiweni kwekhompyutha. Ngokungafani nezilimi ezisezingeni eliphezulu njenge-C++ noma i-Java , ezisebenzisa imiyalelo engaqondakali nephathekayo, izilimi zokuhlanganisa zithembele emiyalweni ethile kumprosesa oqondiwe.
Iqhaza lolimi lokuhlanganisa ezinhlelweni
Ulimi lokuhlanganisa lubalulekile ekuthuthukisweni kwesoftware yezinga lesistimu nasekuthuthukiseni amakhodi. Abahleli bezinhlelo abasebenzisa izilimi zokuhlanganisa banokulawula okukhulu ku-hardware futhi bangasebenzisa ngokugcwele izinsiza zomshini.
Izinzuzo kanye nokubi kolimi lokuhlanganisa
Ukusebenzisa ulimi lokuhlanganisa kunezinzuzo kanye nokubi. Ezinye zezinzuzo zihlanganisa:
- Ukulawula okugcwele kwehadiwe: Abahleli bangafinyelela izici ezithile zehadiwe futhi bathuthukise ukusebenza kohlelo.
- Ukusebenza kahle: Ikhodi ebhalwe ngolimi lokuhlanganisa ingasebenza kahle kakhulu mayelana nokusetshenziswa kwezinsiza zekhompyutha.
- Ukuqonda okwengeziwe kokusebenza kwangaphakathi komshini: Abahleli abasebenzisa ulimi lokuhlanganisa banokuqonda kangcono ukusebenza kwangaphakathi komshini futhi bangasusa izinkinga ezingeni eliphansi.
Kodwa-ke, kukhona futhi ukungalungi kokusebenzisa ulimi lomhlangano:
- UbunzimaUlimi lokuhlanganisa kungaba nzima kakhulu ukulufunda nokusebenzisa uma luqhathaniswa nezilimi ezisezingeni eliphezulu.
- Ukuncika kwezingxenyekazi zekhompyutha: Ikhodi ebhalwe ngolimi lomhlangano iqondene nehadiwe futhi ayiphatheki phakathi kwezakhiwo ezahlukene zekhompyutha.
- Ingozi eyengeziwe yamaphutha: Njengoba umhleli enolawulo olukhulu ku-hardware, kuphinde kube nengozi enkulu yokwenza amaphutha okungaba nzima ukuwalungisa.
Umlando wolimi lokuhlanganisa
Ulimi lomhlangano lunomlando omude osukela ezinsukwini zokuqala zekhompyutha. Njengoba amakhompyutha etholakala kalula futhi kwathuthukiswa izilimi ezintsha zokuhlela, ulimi lokuhlanganisa lwaba ithuluzi elibalulekile kubahleli bezinhlelo ababedinga ukulawula nokusebenza kahle ezinhlelweni zabo.
Izilimi zomhlangano wokuqala
Izilimi zokuqala zomhlangano zathuthukiswa ngawo-1950, kanye namakhompyutha okuqala e-electronic. Lezi zilimi zomhlangano zakuqala zazixhunywe eduze nesakhiwo somshini futhi zazisekelwe emiyalweni yekhodi yomshini.
Ukuvela kolimi lokuhlanganisa
Njengoba ubuchwepheshe bama-computer buthuthuka, nolimi lokuhlanganisa lwakhula. Izici ezintsha zethulwa futhi ukufunda nokusebenziseka kwathuthukiswa. Esikhundleni sokuthembela kuphela emiyalweni yekhodi yomshini, izilimi zokuhlanganisa zaqala ukusebenzisa amagama akhumbulayo kanye nezimpawu okwakulula ukuthi abahleli bazikhumbule futhi baziqonde.
Izilimi zokuhlanganisa zesimanje
Njengamanje, kunezinhlobo ezahlukene zezilimi zokuhlanganisa zesimanje ezisetshenziswa kuzo zonke izakhiwo zamakhompyutha ezahlukene. Ezinye izibonelo ezidumile zifaka phakathi ulimi lokuhlanganisa lwe-x86 lwabaprosesa be -Intel ne-AMD , ulimi lokuhlanganisa lwe-ARM lwamadivayisi eselula, kanye nolimi lokuhlanganisa lwe-MIPS lwezinhlelo ezifakiwe.
Izibonelo eziyisisekelo ngolimi lokuhlanganisa
- Isibonelo: Phrinta okuthi "Sawubona Umhlaba" esikrinini
Ikhodi yokuhlanganisa elandelayo ibonisa ukuthi ungaphrinta kanjani umlayezo othi "Sawubona Umhlaba" esikrinini usebenzisa okokufaka okuyisisekelo nemisebenzi yokukhiphayo yesistimu yokusebenza. Sicela uqaphele ukuthi lesi sibonelo singahluka kuye ngohlelo oluthile lokusebenza kanye nezakhiwo osebenza kuzo.
