JAVA in DAILY LIFE

13. ASET
Java is used in a variety of computing platforms from
embedded devices and mobile phones on the low
end, to enterprise servers and supercomputers on
the high end. Java is nearly everywhere in mobile
phones, Web servers and enterprise applications,
and while less common on desktop computers; Java
applets are often used to provide improved
functionality while browsing the World Wide Web.
