If you're not at some level knowledgeable about computer software, and better yet computer hardware and software, then you may not find this book interesting. Or perhaps even understandable. If on the other hand you have some understanding of computer hardware and software you will not only find this book informative, you'll also come away impressed with Grace Hopper's role in the evolution of computing.
World War II presented a variety of complex mathematical problems the solutions to which would provide the military with a competitive edge. So early computer hardware was designed to function as "super calculators" that could more quickly solve those problems than could a team of humans, typically women, working with mechanical desktop calculators.
That hardware's clumsy methods for getting a problem into the machine required a sophisticated knowledge of math and the computing machinery. Enter Grace Hopper who possessed not only the requisite mathematical knowledge, but also the interpersonal, organizational, and communications skills that enabled her to make major contributions to computing, especially computer software, during and after World War II.
The magnitude of those contributions are too many to enumerate in this comment. Suffice it to say that if one has a general interest in the subject matter, this informative book tells a good story...
