They are easier and more efficient for programmers because they are closer to natural languages than machine languages. Ada Lovelace in the 19th century, for the planned Analytical Engine.
Both fields study software and its creation. However, prior to 1946, software was not yet the programs stored in the memory of stored-program digital computers, as we now understand it.

There are many different types of application software, because the range of tasks that can be performed with a modern computer is so large—see list of software.
