What is the difference between a VM and a compiler?
compiler transfer one language to another, like javac transfer java code to jvm bytecode. vm execute languages and changes states.
It's true, they both have to convert one form of code into another, but this doesn't neccessarily make a VM a compiler in a strict sense..
What is virtual machine in compiler?
Virtual machines are programs that compile an intermediate language down to machine code.
They are the result of an intelligent two-step compiler design.
VMs allows multiple languages to be compiled down to machine code without needing separate hardware-specific compilers for each individual language..
What is VM in compiler?
In computing, a virtual machine (VM) is the virtualization or emulation of a computer system.
Virtual machines are based on computer architectures and provide the functionality of a physical computer.
Their implementations may involve specialized hardware, software, or a combination of the two..
What programming language uses a virtual machine?
Besides Java, other languages can run on the Java Virtual Machine like Scala, Kotlin, Groovy, Clojure.
In the following sections, we'll take a high-level look at the most popular JVM languages..
- The difference is that instead of compiling the source code into a machine language, it is output into byte code for the runtime environment's "virtual machine".
This virtual machine intercepts the byte code instructions and translates them into computer-specific commands. - This type of VM has become popular with the Java programming language, which is implemented using the Java virtual machine.
Other examples include the Parrot virtual machine and the .
NET Framework, which runs on a VM called the Common Language Runtime. - Virtual machines resemble real processors, but are implemented in software.
They accept as input a program composed of a sequence of instructions.
Virtual machines often provide more than the simple interpretation of programs: they also abstract the underlying system by managing memory, threads, and sometimes I/O.
