Java Virtual Machine

Java Virtual Machine (JVM) - A program that runs under an operating system and interprets Java programs. The Java Virtual Machine ideally will not allow any harm to come to the computer because it has no control of the operating system and acts as if it is a separate computer. Thus, if a malicious Java program were to crash the Java Virtual Machine the operating system would remain stable. Another advantage of this mechanism is that different OSes can have their own Java Virtual Machines that should act identically. Thus Java should be able to be run across different platforms easily with no code changes. In the real world, however, this is not always the case.

The Java virtual machine (JVM) is the cornerstone of the Java and Java 2 platforms. It is the component of the technology responsible for its hardware- and operating system- independence, the small size of its compiled code, and its ability to protect users from malicious programs. The Java virtual machine is an abstract computing machine. Like a real computing machine, it has an instruction set and manipulates various memory areas at run time. It is reasonably common to implement a programming language using a virtual machine; the best-known virtual machine may be the P-Code machine of
