When we talk about Conceptual Model , so we definitely mean the High Level of information. Unlike Physical Model, Conceptual model doesn't discuss the data, but it discuss the process. as we told its a high level approach to understand the logic/Process.

Conceptual modeling is the very first level of data modeling once gathering the Business requirements. It tells about only the Entity and attributes , not the relations(constraints) or physical tables and columns so that it will be helpful design for the users and architects while reverse engineering. It tells clearly about the what are all the possible entities (tables in physical model) and their attributes required for this software/application, so that later altering the design will be prevented.. Finally we can directly get the relational model using available tools.
