Yes - In every machine that has the Java Runtime Environment (JRE) installed, the JVM will be available.

What is purpose of JVM?
JVM stands for Java Virtual Machine The JVM is the system in which our Java programs are executed.
Is JVM a software or hardware?
JVM stands for Java Virtual Machine, it is software.
Is Jvm in the system?
The JVM (Java Virtual Machine) is a part of the JRE (Java Runtime Environment).The JRE is comprised of the JVM and the Class Library.The JVM takes the java language and compiles it into Bytecode which can then be interpreted as machine code by the platform(OS). The JVM will compile byte code specific to the OS it is being deployed upon. The JVM allows the Java language to be platform independent.
Why it is not possible to execute java program on machine which does not have JVM installed on it?
when a java program is compiled it is converted into a non executable code which is byte code, and this byte code can only be interpreted by JVM. so a java program can't be executed on a machine which doesn't have JVM installed on it.
Why is the JVM platform dependent?
That depends on how you look at it. The point of the JVM is to allow Java bytecode to be executed on any platform, regardless of what machine it was compiled on. The actual implementation of the JVM, however, must be platform-specific.
What is meant by JVM in applets?
Answer: JVM is nothing but java virtual machine,it is a software used to convert the bytecode(highly optimizes set of instructions) to machine code. so, now applet is a small java program run by a web browser.thus now we can understand for what JVM is used or mean in applets.Answer: In other words, JVM (Java virtual machine) is simply the component used to run software written in the Java language.
Is Java is platform dependent or independent?
Java is not machine dependent. High-level Java source code is compiled against the JVM which produces Java byte code, the lower-level native language of the JVM. At runtime, the JVM interprets the byte code to produce the required machine-dependent code. Every platform that supports Java has its own JVM, thus the same byte code can execute upon any supported platform. The translation from byte code to machine-dependent code is handled solely by the platform JVM.
How one jvm call another jvm?
As of Java 6 every JVM runs an MBeanServer which you can connect to via a JMX RMI connection and then invoke methods on services hosted in the remote JVM's Mbean server.
Why java is plateformindepedent?
Java enabled machines (PC, Mac, Smart Phones,etc.) all have their own version of whats called the JVM (or java virtual machine). The JVM takes source code written by programmers and converts into the corresponding machine code. For example a JVM running on a PC would convert the source into machine code corresponding to a PC and so on.
This training system requires use of the Java Virtual Machine JVM?
True
Is it possible to run java program without JVM?
No. Java programs run in the Java Virtual Machine (JVM) - without it your computer won't know how to handle Java bytecode.
Can you have more than one jvm?
Yes you can. PS: Each JRE version would have a different JVM. If you have multiple JRE versions in your machine then you would have multiple JVMs
