• “Is an umbrella term used to describe
technologies that enable people to
access network services
anyplace, anytime, and anywhere. ”
Other definitions :
• Mobile computing is the use of
computers in a non-static
environment.

7. • Today, technological advances are
shaping a new computing
environment where the user is free
from the need to work at a specific
location, and is even enabled to
work while on the move.
Briefly
• Mobile Computing=Mobile (Moving)
+ Computing (using computer)
