Answer Posted / sayed waseem tutorails phd fro
Data abstraction is any device that allows you to treat data
as humans encounter it rather than as it is stored on machine.
At the lowest level, all primitive data types are
abstractions -- as programmers, we don't usually have to
deal with data at the bit level (which is how it is
ultimately stored) but as integers, floating point numbers,
characters, etc.
We then add layers onto that abstraction -- maybe two
integers represents a Point, or we and enumerations to
represent the months of the year, days of the week, etc.
