How and why are variable names used in programming to process data?
Variable names are used so the code is readable. When the code is compiled to machine languages, it no longer uses the variable names to understand it's operations...sometimes variable names are kept as metadata to help debug but the computer does not need them to execute the program...they are for us so we can easily understand what we are doing.
What is this native code and what is difference between native code and machine code?
They are the same thing. Every machine type has its own version of machine code, the native language of the machine (native machine code). All high-level code must be converted to native machine code before it can execute. Machine code is machine dependent but high-level code is generally machine-independent, thus the same source code can generally be converted to suit any type of machine using a suitable compiler or interpreter.
Is assembly language to machine language one to one?
Not quite but very close. If you disassemble a machine code program you do not get the original assembly. Aside from stripping out all comments and variable names, the "structure" of the original assembly is lost. However, if you compare the code side-by-side you will be able to see how similar they actually are and how easy it would be to reverse engineer the code to reproduce a facsimile of the original source code.
What is compiled code?
Compiled code is plain-text source code that is translated from an English-like, high-level language into either machine code or byte code by a program known as a compiler. Machine code is the native language of the machine, consisting of binary patterns that represent a sequence of machine instructions and their operands. Byte code is the native language of a virtual machine; a machine that only exists within a computer's memory. The virtual machine is simply a program that interprets the byte code in order to produce the actual machine code. Unlike machine code which must be compiled separately for each platform, byte code will run on any platform that has a corresponding virtual machine implementation.
What are the five examples computer language?
Machine code, assembly language, COBOL, FORTRAN and C. Machine code is the only language that is native to the machine. All others must be converted to machine code.

Is the machine language machine dependent?
Machine code is machine-dependant because every machine architecture has its own version of machine code. The code is non-portable because only the machine for which the code was intended will be able to understand it.

What is the code required to convert an integer variable to a string variable in Java?
There are several different methods to convert an integer variable to a string variable in Java. For example, one can use the following code to convert an integer variable to a string variable: Integer.toString(number)
What is BYTE Code in java?
Java byte code is the code that is output by the Java compiler. Byte code is not machine code, it must be interpreted to create the machine code. This is handled by the Java virtual machine. Pretty much every platform produced today has a Java virtual machine implementation, so the same byte code can be executed upon any machine. Byte code can be regarded as being the native language of the virtual machine, as opposed to machine code which is the native language of the physical machine.
What is byte code and native code?
native code is machine code each machine has its won set of istruction one machine's native code won't run on another While bytecode is what java produces and it can run on any machine. when we run bytecode it first get to compile to machine code and then get to run.

Bytecode is machine dependent or independent?
Because machine code only understsnd by computer in form of 0,1 and byte code not machine code and store in .class of java library it is at the 2nd stage of conversion and the machine code at the final stage and end stage so byte code under stand by any machine by the java library not convert into machine code i.e understand by machine kuldeep singh ssimt
