A lack of computer skills could be damaging the career chances of young people, a charity has warned.
More than one in 10 young people do not think their computer skills are good enough to use in the job they want, the Prince's Trust said.
The research follows a £500,000 donation by hip hop star will.i.am to the Trust last year.
His donation will be used on projects to improve STEM (science, technology, engineering and mathematics) skills.
"I was intimidated by science and advanced maths," said the music star, who donated his fee for appearing on BBC talent show The Voice.
"When I say, 'Hey kids, you guys should want to be scientists, technicians, engineers and mathematicians...' I say that because I too am going to school to learn computer science.
"I'm taking a computer science course, because I'm passionate about where the world's going, curious about it and I want to contribute," he told the BBC.
Valerie Thompson from the E-Learning Foundation, which aims to provide learning technologies to children both at home and at school, said that while will.i.am's donation was "fantastic", there remained "a very significant challenge".
"That [donation] would buy 2,000 children an iPad, and we've got 750,000 children who can't get online at home," she told the BBC.
"This wouldn't be so bad if they had great access at school, but there remains a postcode lottery, with some schools providing barely more than an hour a week of computer access. No wonder they lack the skills to prepare a good CV!"
She added that there is money in the system which could be used to improve computer access at schools, pointing to the pupil premium, external, which is paid to schools to support disadvantaged pupils, rising to £1.875bn in 2013-14, or £900 per disadvantaged child.
"So the solution is there if schools are prepared to use the new discretionary powers they now have over what to spend their budgets on," she said.
