Cloud-computing enables mobile devices to provide users with access to a wide variety of applications and services. Which of the following is a disadvantage of mobile devices?

Question

Options

• AMobile devices cannot accommodate Web browsing.
• BMobile devices cannot easily be used for checking e-mail.
• CMobile devices cannot access software hosted on remote servers.
• DMobile devices cannot accommodate large database installations or applications.

• A
  4% (2)
• B
  2% (1)
• C
  5% (3)
• D
  89% (51)

Explanation

Mobile devices have limited processing power, storage, and RAM, making them fundamentally incapable of hosting large database installations or running resource-intensive enterprise applications locally - this is why D is correct, and it's precisely the gap that cloud computing helps bridge by offloading that work to remote servers.

Why the distractors are wrong:

• A is false - mobile devices have supported Web browsing since early smartphones (Safari, Chrome, etc.)
• B is false - email is one of the most common and native uses of mobile devices
• C is the opposite of true - accessing software on remote servers (i.e., cloud apps) is exactly what mobile devices do well

Memory tip: Think "big = bad on mobile." Databases are big, phones are small. Everything else (web, email, cloud access) is lightweight by design - mobile handles those just fine.
