Let's face it: Computer science has a diversity problem. Tech giants like Apple, Microsoft, Facebook, and Twitter — just to name a few — are still predominantly staffed by white males.

One of the main reasons is that those in Black and Hispanic communities aren't getting much exposure to computer science and careers in technology, and those who are interested in the field often lack the resources to learn more, according to Facebook's Global Director of Diversity, Maxine Williams.

The social network wants to change that, so it has launched a new site where underrepresented groups can learn more about computer science and find resources to help them get started. Dubbed TechPrep, the hub was designed for English and Spanish speakers and includes "hundreds of resources," organized by age range, skill level, and the kind of information needed.

That includes games, books, information about upcoming community events, and in-person opportunities. Learners can also get inspired by reading profiles of real people pursuing careers in computer science while parents and guardians can find resources to help guide their kids.

Recent research from consultancy McKinsey revealed that 50 percent of Blacks and 42 percent of Hispanics say they would be good at working with computers, compared to 35 percent of Whites and 35 percent of Asians, according to Williams. However, 77 percent of parents said they don't know how to help their child pursue computer science.

"Being encouraged to pursue computer science by a parent or guardian is a primary motivator for women, Blacks and Hispanics," Williams wrote. "By exposing people to computer science and programming and guiding them to the resources they need to get started, we hope to reduce some of the barriers that block potential from meeting opportunity."

Several companies has committed millions this year to boost diversity, from Apple's $50 million to Intel's $300 million.
