The machine-independent phase in a compiler refers to the stages of compilation that do not depend on the target machine's architecture. This phase includes syntax analysis, semantic analysis, and intermediate code generation, where the compiler converts high-level source code into an intermediate representation (IR). The purpose is to optimize the code and perform various analyses without considering the specifics of the hardware, allowing for greater portability across different platforms. Once this phase is complete, the compiler moves on to machine-dependent phases that generate the final machine code.
The size of an integer is compiler-dependant. The compiler itself is machine-dependant so it could be argued they are in fact machine-dependent, however we don't write code to suit the machine, we write code to suit the compiler, even when the code is machine-dependent.
Quite simply, a 16-bit compiler is a compiler for a 16-bit machine.
FORTRAN (FORmula TRANslator) is the best-known earliest example of machine independent language. This is where the language is not dependent on the characteristics of the computer. COBAL (COmmon Business-Orientated Language) is the other type of programming language that is machine independent. COBAL was developed by the US Navy for business applications.
A load and go compiler generates machine code and then immediately executes it.
No. (Of course you should specify what compiler you are talking about.)

The compiler translates source code into machine code. As opposed to java, this is a machine specific operation.
Yes, it's. The only exception I can think of is Itanium. But even that case compiler can be configured in a way that you do need to worry about that.

compiler used to convert high level language coad into machine level language
A compiler or interpreter converts high-level programming languages into machine code that can be understood and executed by the computer's hardware.
No. (Of course you should specify what compiler you are talking about.)
Assembler/compiler converts programs into machine language.
