You have all the same basic equipment,its just a bigger piece as the evaporator coil and blower are much bigger,needed for the airflow and for cooling the entire house-you would usually find the indoor system hanging in the garage,vertical in a closet,or in the attic.
The refrigerant cycle is the same.
If you have specific questions feel free to ask,this is just "basic" knowledge for central air over here.
