As per IDC data, the commercial PC segment recorded 1.04 million unit shipments in the second quarter of 2015, registering a 4.5 per cent quarter-on-quarter growth against the preceding quarter.
"Various announcements and initiatives made by the government on boosting economic growth had positive impact on the sentiments of the business community," Kumar said.
In order to sustain this buoyancy, it is vital that implementation of reforms continues at a steady pace, he added.
However, the consumer PC market recorded shipment of 1.15 million units, a quarter-on-quarter drop of 1.3 per cent over January-March 2015 quarter.

As a result, inventories continue to build up and vendors are hoping for a seasonal turnaround in the July-September 2015 quarter, Yadav added.
