Virtual Machine (JVM)

A Virtual Machine (VM), such as the Java Virtual Machine (JVM), is a software layer that runs programs in a controlled environment, independent of the underlying hardware or operating system. It interprets or compiles code into machine instructions suitable for any device, ensuring portability, security, and stability. Think of the JVM as a translator that allows Java programs to run seamlessly across different computers without needing changes. This abstraction enables developers to write code once and run it anywhere the JVM is installed, making software more flexible and reliable.
