Bájtkódra

Bájtkódra, often referred to as bytecode, is a form of computer code that is an intermediate representation between source code and machine code. It is not directly executable by the computer's central processing unit (CPU) in the way that native machine code is. Instead, bytecode is typically executed by a virtual machine (VM) or an interpreter. This separation allows programs written in a high-level language to be more portable, as the bytecode can be run on any system that has a compatible virtual machine installed, regardless of the underlying hardware architecture.

The process usually involves a compiler that translates source code, such as Java or Python, into bytecode. This bytecode is then processed by a virtual machine, which might interpret the instructions directly or further compile them into native machine code for the specific platform. This interpretation or compilation step adds a layer of abstraction and can sometimes result in slower execution compared to native code, but the benefits of portability and easier development often outweigh this drawback. Many popular programming languages, including Java, Python, and C#, utilize bytecode as a fundamental part of their execution model.
