If you are in windows environment and your database server is somewhere on the network, so the following things happen: SQL* plus transfers your sql query over the network on the database server. SQL* Plus waits for the reply from the database server. The database server execute the query and transmit result to the SQL * plus. Then SQL * Plus display the query result on computer screen. If you are not running in a networked windows environment, the same thing happens. The only difference might be that the database server and SQL * Plus is running on same physical machine.
