Zeziphi ezi ntlobo zimbini zeefayile zesixhobo?
Kukho iindidi ezimbini ngokubanzi zeefayile zesixhobo kwiinkqubo zokusebenza ezifana ne-Unix, ezaziwa ngokuba ziifayile ezikhethekileyo zomlinganiswa kunye nokuthintela iifayile ezikhethekileyo. Umahluko phakathi kwabo ulele ekubeni ingakanani idatha efundwayo kwaye ibhalwe yinkqubo yokusebenza kunye ne-hardware.
Zeziphi iimpawu eziphambili ze-Unix?
Inkqubo yokusebenza yeUNIX ixhasa ezi mpawu zilandelayo kunye nezakhono:
- Ukwenza izinto ezininzi kunye nabasebenzisi abaninzi.
- Ujongano lwenkqubo.
- Ukusetyenziswa kweefayile njengezithintelo zezixhobo kunye nezinye izinto.
- Uthungelwano olwakhelwe ngaphakathi (i-TCP/IP isemgangathweni)
- Iinkqubo eziqhubekayo zenkonzo yenkqubo ebizwa ngokuba yi-“daemons” kwaye ilawulwa yi-init okanye inet.
Uthini umahluko phakathi kwebhloko kunye nokugcinwa kwefayile?
