Machine language (or machine code) is entirely dependent upon the architecture. Even within the same family of architectures, there can be significant differences between the machine code. For instance, 32-bit and 64-bit systems based upon the Intel x386 family of processors need to address memory in different ways, such that 64-bit code cannot execute on a 32-bit system. Even on systems with similar addressing models, there can be significant differences; some use little-endian binary representations while others use big-endian. And while many core operations are reasonably common to all modern processors (MOV, JMP, ADD and so on), the actual operation codes can differ significantly while certain operations supported by a given architecture may not be supported by the previous generation of that same architecture.

Why assembly level language is called machine dependent language?
Machine languages are composed of instructions intended to be read directly by the microprocessor (the computer's CPU). The manufacturer of the CPU determines it's "INSTRUCTION SET" ASSEMBLY LANGUAGE on the other hand IS NOT machine dependent. The same commands ADD, Divide, Move, etc are universal. HOWEVER the ASSEMBLY LANGUAGE has to have an INTERPRETER for EACH CPU, and that will translate the Universal ASSEMBLY language to the MACHINE SPECIFIC code required to program the CPU.
Why does micro processor work in assembly language?
Microprocessors work in microcode, not assembly language. Microcode processes machine instructions, which are often assembled from assembler languages; higher level languages often convert each line of code into multiple lines of assembler language before their ultimate compilation into an executable. The assembler language contains mnomonics that are used to translate each line of source code into a machine instruction. When those machine instructions are loaded in memory, the CPU will use microcode to interpret and execute those instructions. Barring some experimental CPUs that use non-traditional machine code (such as Sun's Java CPU), all production-class CPUs use machine instructions as their basis for software execution.
How does a high level language relate to the microprocessor's instruction set?
Generally speaking, it doesn't relate at all. If it did, it wouldn't be high-level, it would be machine-dependent. The relationship between the high-level code and the machine-code is ultimately determined by the language translator (compiler and/or interpreter) but, unlike assembly language which maps 1:1 with the microprocessor instruction set, compilers and interpreters are code generators and there is seldom a 1:1 relationship between the high-level source code and the machine code.
Why Java is called high level language?
Low level computer languages require the programmer to know the machine code or assembler language for the computer CPU targeted including low-level functions like memory allocation and memory deallocation.A high-level programming language is a programming language with strong abstraction from the details of the computer.The Java programming language is not only a high-level language, but is also machine and platform independent in that the same compiled byte-code can run on different platform and CPUs without recompiling.
Short note on high level language?
Generally languages are used for communication, In the case of computers languages are used to communicate with the Hardware. Language consist of set of rules and syntaxes to frame the valid instructions to work with the Machines.
What is meant by machine language?
A language at the level of the machine it runs on. AKA Machine code, it's the underlying language that computer CPU's speak.

The language that the CPU understands consisting of a sequence of bits is called?

What are the the languages called?
Low level computer languages require the programmer to know the the assembler language for the computer CPU targeted. They are assembled directly into machine code for that CPU type and no other.High level computer languages are closer to human language (or mathematical notation) and the code written in them is 'generic', it will work on any CPU type. This is possible because the high level language is first compiled before specific machine code is generated. All CPU types therefore need their own high level language compiler but once this is developed any code written in the high level language can be used on that CPU type.Examples of high level languages are:FORTRANCOBOLAlgolPascalPearlPythonC, C++etc.
How do you speak CPU language?
The computer language to directly communicate with the CPU is known as Machine language, or Binary. Its closest relative language would be Assembler which is more programmer-friendly. In general, any programming language speaks to the CPU, but is converted into its lowest form through an interpreter.
Why machine language program written from one computer will not run on another computer with different CPU?
I'm assuming it has to do with the architecture of the CPU.
What are advantages of a machine language?
Advantage? That is not the right question. there is really NO ANSWER.Machine language is the BASE LANGUAGE that a Machine work in.Example: Go Left, Go Right is what we first think of as Machine language. But actually the commands: "Move memory location 1024 to CPU register location 2", Then "shift That register 1 BITE left", then "store back in location 1024"The above are examples of machine language.The first is that of mechanical systems that have HARDWARE to define 'Go' .. be it left or right. The second is an example of 3 steps of Machine instructions in a computer's CPU. One step in a CPU can take 1 billionth of a second.So Assuming that you mean COMPUTER Machine language?IT is easier to program in non-machine language. BUT ALL languages will convert or TRANSLATE the code you type into machine CODE. It is VERY hard to program in Machine code (The hardness determined by the CPU and what it controls).COMPUTERS DO NOT RUN ON ANY OTHER LANGUAGE BUT 'MACHINE CODE'. That is all they understand. So It MAY be an advantage to instruct in machine code if there is an advantage otherwise there is not. Confusing? ENTIRE VOLUMES OF BOOKS have been written on this topic.But when it comes down to the basics? There is nothing more basic than Machine Code.ce
What is called the collection of commands that a specific CPU executes?

What is the purpose of the CPU in computer?
CPU stands for central processing unit. As the name implies, the CPU processes everything the computer does and handles everything that goes on in a computer. The CPU is often referred to as the brain of the computer since everything goes through the CPU first. The purpose of the CPU is to read machine language and do what it is told by it. The machine code are the directions on what the CPU should do, but the CPU is needed in order to read this code.
How assembly language communicate with the CPU of any computer devices?
Assembly language code is the lowest-level form of programming before Machine code (binary), and each command in Assembler code directly references binary commands which tell the CPU what to do.
