JVM stands for Java Virtual Machine, which is a software component that provides an environment for executing Java bytecode. Java bytecode is a machine-readable code that is generated when Java source code is compiled. The JVM interprets this bytecode and executes it on the computer.
The JVM is designed to be platform-independent, which means that Java programs can run on any platform that has a JVM installed, without the need for recompiling the code. The JVM provides a layer of abstraction between the Java code and the underlying hardware and operating system, which makes Java programs highly portable.
The JVM also provides other features such as memory management, garbage collection, and security, which are essential for running Java applications. The JVM manages the memory used by Java programs and automatically frees up memory that is no longer needed. The garbage collector is a component of the JVM that performs this memory management task.
The security features of the JVM include a sandbox environment, which isolates Java programs from the underlying system, and a strict security model that prevents Java programs from accessing sensitive resources without proper authorization.
In summary, JVM is a software component that provides an environment for executing Java bytecode. It interprets Java bytecode, manages memory, performs garbage collection, and provides security features that are essential for running Java applications. The JVM is designed to be platform-independent, which makes Java programs highly portable.
