Hand-held computers and mobile phones that
support Java also need a Java interpreter to run the
applications. Since the Java Virtual Machine (JVM)
was not the optimal interpreter for devices with
small memory capacity and slower processors,
Sun developed K Virtual Machine (KVM). A KVM
requires only 40-80 KB of memory and can run on
processors with low clock frequency. KVM is only
used for J2ME CLDC. PersonalJava relies on the
Java Virtual Machine (JVM).
