Mobile Devices Are Becoming Major Computing Platform!

21

Relevance of Java Technology• Before Java technology:

> Software development and deployment was painful (Using proprietary technologies)

> New software installation was close to impossible (Users have to buy new phones)

• With Java technology:> Most of the mobile devices already have Java platform

pre-installed> Java is the most popular programming language for

writing mobility applications> You can download many Java applications just in time

• Automobiles are by nature mobile

NetworkingNetworkingEverywhere byEverywhere byEverything &Everything &EverybodyEverybody
