The correct answer is D. All of the mentioned.
Modeling, computing, and software are all essential components of the computing industry. Modeling is the process of creating a representation of something, such as a physical object or a system. Computing is the process of performing calculations and manipulating data. Software is a set of instructions that tells a computer what to do.
The dream of making computing as a utility is a long-standing one. The idea is that computing should be available to everyone, just like electricity or water. This dream has been driven by the increasing power and affordability of computers, as well as the development of new technologies, such as the internet.
Today, computing is more accessible than ever before. However, there are still many challenges to overcome before it can be truly considered a utility. One challenge is the digital divide, which refers to the gap between those who have access to computers and the internet and those who do not. Another challenge is the lack of digital literacy, which refers to the ability to use computers and the internet effectively.
Despite these challenges, the dream of making computing as a utility is still a powerful one. It has the potential to transform the way we live, work, and learn.
