1. Hordhac
Qalabka korontada ku shaqeeya waa nooc ka mid ah qalabka korontada.Khadadka dibadda ee golaha beddelka ayaa marka hore galaya koontaroolka ugu weyn ee golaha, ka dibna geli furaha kontoroolka hoose.Laan kasta waxaa loo dejiyaa hadba sida ay u baahan tahay.Tusaale ahaan, aaladaha, kontoroolka otomaatiga ah, furayaasha birlabeedka, kala duwanaanta AC, iwm. Qaar ayaa sidoo kale lagu qalabeeyay qol korantada sare leh iyo armaajooyinka qolka korantada yar, basaska tamarta sare leh, sida warshadaha korontada, iwm, iyo qaar. sidoo kale waxaa lagu qalabeeyay culeys yar oo wareeg ah oo loogu talagalay qalabka muhiimka ah.
Golaha beddelashadu waxa uu leeyahay hawlo ay ka mid yihiin khadadka soo galaya iyo kuwa baxaya, fiilooyinka soo galaya iyo kuwa baxaya, isku xirka baska, iwm iyo shirkadaha macdanta, guryaha la dego, daaraha dhaadheer, iwm.
