IT spending worldwide is projected to touch $3.6 trillion this year, much higher than in 2010, according to global research group Gartner.
The higher spending is expected to be bolstered by media tablets such as iPad.
"Worldwide IT spending is forecast to total $3.6 trillion in 2011, a 5.6% increase from $3.4 trillion in 2010," Gartner said.
The outlook has been revised higher from earlier growth projection of 5.1%.
The inclusion of expenses on media tablets has increased this year's computing hardware growth outlook to 9.5% from 7.5%.
"Worldwide media tablet spending is projected to reach $29.4 billion in 2011, up from $9.6 billion in 2010," Gartner said.
Globally, spending on media tablets is expected to rise at an annual average rate of 52% through 2015.
