Intaa ka dib, marka loo eego shuruudaha la cayimay, mishiinka buufinta jaakad la'aanta ee cadaadiska sare leh ayaa loo isticmaalaa in lagu buufiyo isla nooca iyo tirada jaakad hoose (primer) sida uu ansixiyay injineerka kormeeraya. Ka dib marka jaakada hoose ee si buuxda loo qalajiyo, calaamadaynta waxaa lagu sameeyaa mashiinka calaamadaynta kuleylka kuleylka leh ee iskiis u socda ama mashiinka calaamadaynta kuleylka kuleylka ah ee gadaal ka socda.
