How is memory address used to access an abstract data type that is larger than 1 byte?

In computer memory, each abstract data type (ADT) larger than 1 byte is stored starting at a specific memory address, which acts as a reference point. Accessing the elements of the ADT involves using the base address along with an offset that corresponds to the specific element or field within the ADT. For example, if the ADT is an array or a structure, the memory address of the first element is used, and subsequent elements can be accessed by adding the appropriate offsets based on the size of each element. This allows for efficient retrieval and manipulation of complex data types in memory.
