Mobile ComputingMobile Computing

• “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.

6

• 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)7

• The Benefits of Mobile Computing– It is very important nowadays in business

and commerce …. Etc.

It has 3 benefits :1) Improved decision making

2) Increased productivity and reduced costs

3) Improved customer relations: 

25

Improved decision making :

– The ability to collect, access and evaluate critical business information quickly and accurately means better decision making

that can have a far-reaching effect on your company's ability to compete successfully 

26

Increased productivity and reduced costs

– increased sales per sales person, more service calls per repair person, less time spent by professionals on administrative

work .

27

Improved customer relations

– The success of a business can often be measured by its ability to satisfy customers.

– Cost Effectiveness Paybacks for mobile computing investments can often be measured in months.
