By 2020, experts cited in the Connected Factory Partner Accelerator System Engineer Training believe that how many devices will be plugged into the Internet?

Question

Options

• A800 million
• B10 billion
• C50 billion
• D100 billion

• A
  10% (2)
• B
  5% (1)
• C
  85% (17)

Explanation

Option C (50 billion) is correct because major industry analyses - including those cited in Cisco's Connected Factory training materials - projected that approximately 50 billion devices would be connected to the Internet by 2020, a figure widely associated with the rise of the Internet of Things (IoT). Options A (800 million) and B (10 billion) significantly underestimate the scale of IoT growth projected during that era, while Option D (100 billion) overshoots the consensus estimate by double. The 50 billion figure became a landmark projection in IoT discourse, frequently cited by Cisco and similar technology companies to illustrate the explosive expansion of connected devices in industrial and consumer contexts.

Memory tip: Think "5-0 billion for IoT to go" - 50 is the middle ground between the too-low tens and the too-high hundreds, making it the "Goldilocks" figure that industry experts landed on.
