The research firm projects global IT spending to be about $3.7 trillion this year, representing a 4.2-percent increase from 2012.
Global IT spending was $3.6 trillion in 2012, according to the Gartner Worldwide IT Spending Forecast, which has revised the 2013 outlook for IT spending growth in U.S. dollars, upward from 3.8 percent in the Q3 2012 forecast.
"Uncertainties surrounding prospects for an upturn in global economic growth are the major retardants to IT growth," said Richard Gordon, managing vice president at Gartner. "However, much of this uncertainty is nearing resolution, and as it does, we look for accelerated spending growth in 2013 compared to 2012."
Most of the increase in IT spend has been attributed to the expected profits in the value of foreign currencies versus the dollar.
The latest Gartner Worldwide IT Spending Forecast also predicts the global devices spending to reach $666 billion in 2013.
Devices include PCs, tablets, mobile phones and printers. Global enterprise software spending is forecast to total $296 billion in 2013.
Markets aligned to big data and other information management initiatives, such as enterprise content management, will begin to see increased levels of investment in 2014.
Gartner predicts growth to be predominately flat over the next several years for the global telecom services market. Also, mobile data will represent 33 percent of the total telecom services market by 2016.
IT services firm NCR Corporation was recently named by Gartner as the global market share leader in the retail industry product support for 2011, based on product support revenue analyzed by the IT research firm.
