Market research firm IHS Technology released the latest report shows that as of the end of 2015, the global networking equipment has reached 8.1 billion. These networked devices consist of smartphones, tablets, PCs, TVs and their ancillary devices such as Apple TV and Chromecast, and video devices. Globally, each household has 4 networked devices on average. Equally disturbing is the failure of connected devices. Smartphones undoubtedly dominate the networked devices, with a ratio of 1.8: 1 to the number of PCs and a ratio of 4.6: 1 to tablets.
