What is machine dependent and independent language?

What is machine dependent and independent language?

Webopedia Staff. Refers to a software application that runs only on a particular type of computer. Programs that run on a variety of different types of computers are called machine independent.

Which is machine independent in Java?

Java is platform-independent. Any machine to execute the byte code needs the Java Virtual Machine.

Why Java is machine independent language?

And the answer would be, it’s because of the JVM. The byte code generated by source code compilation would run in any operating system, but the JVM present in a machine differs for each operating system. And this is how java is considered a platform-independent programming language.

Why Java is platform independent and JVM platform dependent?

JVM is platform dependent because it takes java byte code and generates byte code for the current operating system. So Java software is platform dependent but Java language is platform independent because different operating system have different JVMs.

What is machine dependent loader features?

(i) Absolute Loader – Simple and efficient. (ii) Disadvantage is – programmer has to specify the starting address. (iii) One program to run – no problem – not for several. (iv) Difficult to use subroutine libraries efficiently.

What is machine dependent compiler?

Machine-dependent optimization is done after the target code has been generated and when the code is transformed according to the target machine architecture. It involves CPU registers and may have absolute memory references rather than relative references.

What is called machine independent?

machine-independent A term applied to software that is not dependent on the properties of a particular machine, and can therefore be used on any machine. Such software is also described as portable. A Dictionary of Computing. “machine-independent .”

Is java operating system independent?

Java is OS independent language because SAME source code will work in any OS. The issue you’re facing is about the Virtual Machine, which translates java bytecode to each OS, so, Chrome OS still does not support Java because JVM for Chrome has not been developed (yet).

Is JVM machine dependent?

4 Answers. Yes, generally a JVM is platform dependent in the sense that it is implemented for the specific platform. The advantage of using a JVM is that, at least in theory, it makes code written in Java platform agnostic and so the same code could run on any platform without modification to the code.

Is JDK machine dependent?

JDK is platform dependent i.e there is separate installers for Windows, Mac, and Unix systems. JDK includes both JVM and JRE and is entirely responsible for code execution.

What are the features of loader?

2. Loader & its Functions  A loader is a system program, which takes the object code of a program as input and prepares it for execution.  Loader Function : The loader performs the following functions :  Allocation – The loader determines and allocates the required memory space for the program to execute properly.

What is the difference between machine dependent and machine independent?

Summary – Machine Dependent vs Machine Independent Code Optimization. The difference between machine dependent and machine independent code optimization is that the machine dependent optimization is applied to object code whereas, the machine independent code optimization is applied to intermediate code.

Is Java machine independent or machine dependent?

Java is a machine independent language – that is to say any code written and compiled in one machine can be executed on another machine. But, to run this compile code (executables – class files) you would need a machine dependent Java Runtime Environment which has respective Java Virtual Machine. Now, how would you consider Java?

What is machine dependent code optimization?

The output of the code optimizer is given to the code generator, and finally, the target code is built. In machine dependent code optimization, optimization is applied to the source code. Allocating sufficient amount of resources can improve the execution of the program in this optimization.

How does the compiler modify the intermediate code?

After generating intermediate code, the compiler can modify the intermediate code by address calculations and improving loops. While producing the target machine code, the compiler can make use of memory hierarchy and CPU registers.

What is the result of the Java compiler?

The result of the JAVA compiler is the.class file or the bytecode and not the machine native code (unlike C compiler). The bytecode generated is a non-executable code and needs an interpreter to execute on a machine. This interpreter is the JVM and thus the Bytecode is executed by the JVM. And finally program runs to give the desired output.
