C code maps efficiently to machine instructions because of its low level.

Abstract Data Types (ADT)

An abstract data type (ADT) is a data type whose representation is hidden from the client.

When coding an ADT we focus in data and the operations we perform with it, without focusing in its internal implementation.

ADT is a way to provide encapsulation to our program design.
