50
Q

the use of information and communication technology for health services and information by both healthcare professionals and the public.

A

eHealth

51
Q

three key synergistic advanced hardware elements enabling mobile health (mHealth)

A

(1) physical device size,
(2) wireless network access, and
(3) battery life. mHealth is accelerating due to the convergence of the infrastructure of adequate processing power and storage available on mobile devices (e.g., smartphones, advanced tablets, and
wearable/implantable/injectable devices); large capacity redundant storage typically available through cloud computing services; and long-life batteries.

52
Q

Advances in computer hardware continue two trends:

A

(1) more powerful processing in ever-smaller packages and
(2) more power distributed across many, many machines, most commonly seen in cloud services.

53
Q

powerful hand-held computer with an operating system and the ability to access the Internet.

A

smartphone

54
Q

ability of a mobile device to connect with networks in multiple ways is the foundation of mobile computing and
mHealth.

A

Wireless Communication

55
Q
