Why generic data type is not used to store data on some specific object in Salesforce?

Sobject is a generic data type. But if we insert some value in the account object through apex, by using Sobject as data type in place of account data type, we get an error message. why we cannot use sObject in place of any object name?

eg.

sObject add= new Account (name=’ram’);  //it shows error

Account add=new Account (name=’ram’); // this line  executed.
