Machine language is the computer instructions in memory--the actual bits used by the machine hardware or microcode interpreter. To "look" at it, it has to be converted to a human-readable form. Often, it is printed as a sequence of hexadecimal numbers, usually tagged with the memory address. Sometimes it is processed by a disassembler program, which tries to translate the code into assembly language instructions and data. This is not always successful since in machine architectures that mix data and instructions, it can be difficult to determine which program areas are data and which are instructions.

Examples of machine language?
Machine code is the ONLY example of machine language. However, every machine architecture has its own version of machine code; it is the native language of the machine. If you want to examine machine code upon your own machine, use a hex editor. This will show you every byte of the code in hexadecimal form.
What is difference between machine code and assembly language?
Machine language is the actual instructions in computer memory that are fetched into the processor and executed. It is directly executable and consists of what look to most human beings like a bunch of hexadecimal numbers, though a few geeks such as myself can tell it is code instead of numbers. For example, the instructions executing interrupt 21, service 10, are: B410 CD21 Assembly language is a human readable as mnemonics, it translates on a one for one basis into machine language. The computer cannot execute assembly language directly, but human beings who are trained can understand it. The assembly language equivalent of the above instructions is: MOV AH,10 ; prepare for service 10 by putting 10 into AH INT 21 ; vectors into code established in the interrupt table
Why is assembly language efficient?
Assembly uses commands you can begin to understand, like JSR (Jump to subroutine which changes points in a code) machine code on the other hand is the code that the machine reads. This would only look like numbers to you, probably in hex code. Basically the higher level a language is the easier to understand because of the level of abstraction. It goes, machine code, assembly language, then things like C then java or visual basic. In VB you can write commands almost the same as you would construct an English sentence, the compiler then converts this down to machine code which the processor can understand and execute. Got it?
Compare the assembly language with machine language?
Assembly language is 1 step above machine language. In assembly language you can use mnemonics to represent what you want to do. For example, to compare two numbers together I could represent the sequence as:L R1, Value1 load the first valueC R1, Value2 compare against the second valueJG First first value greater than secondAs you can see, there is some symbology here that allows me to determine what the program logic is doing. Note that the above code is not understandable to a computer circuit; it has to be translated to machine code. And that is what assembly code is; a symbolic human representation of what the machine is supposed to do.Machine code on the other hand, is usually the targeted result of translating assembly code to the machine equivalent. The machine circuit only understands a sequence of zeros and ones, and is not immediately understandable to a human. The result of the program sequence above in machine code might look something like:111001101101100000111100011000101010Which makes sense to a machine, but not a human.

it is a brown wooden box with a typing machine inside, this would break the enigma code, the Germans used this machine in WW2

The answer is a code. Take the pictures on the machine and look at your fish. The pictures on the machine tell you the code.

What is done during compilation?
The code of source file stored on the disk must be translated in to machine language. this is the job of the compiler. The c compiler is actually two separate programs :"PREPROCESSOR",TRANSLATOR.The preprocessor reads the source code and prepares it for translator.while preparing the code , it scans for specials instructions known as preprocessor commands. These commands tell the preprocessor to look for special code libraries, make substitutions in the code, and in other ways prepare the code for translation in to machine language .the result of possessing is called translation unit .after the preprocessor has prepared the code for compilation, the translator does the actual work converting the program in to machine language . the translator reads the translation unit and writes the resulting "object module".an object module is the code in machine language. even though the output of the compiler is machine code, it is not yet ready to run : that is not yet executable because it does not have the required c and other functions included

What does machine code look like and how is it different from high-level programming languages?
Machine code is a low-level programming language that consists of binary code that can be directly executed by a computer's central processing unit (CPU). It is made up of sequences of 0s and 1s that represent specific instructions for the CPU to carry out. Machine code is specific to the hardware architecture of a computer and is difficult for humans to read and write. On the other hand, high-level programming languages are designed to be easier for humans to understand and write. They use more human-readable syntax and are closer to natural language. High-level languages need to be translated into machine code before they can be executed by a computer, usually through the use of a compiler or interpreter. This translation process allows high-level languages to be more portable across different hardware platforms compared to machine code.
What are the differences between computer program language and human language?
MOTHER TONGUE OF A COMPUTER:Everyone of us knows at least one or two human languages such as English ,Urdu ,Chinese .One of there is our tongue , the language which we learned from childhood . Similarly , computer have their own "mother tongue ". The mother tongue of a computer is machine language.Machine language instructions are in binary form.computer language(1) A programming language or machine language.(2) Everyday computer language, which includes computer technologies and concepts as well as hardware and software products .MACHINE LANGUAGE ADVANTAGES :Machine language program is written is machine code.This is the only language that the computer can understand directly . The main advantages of machine languages are:Machine code is carried out faster as it is the "native language" of the computer.It occupies less momory space.DISADVANTAGES :However , it has the following disadvantages:Each type of computer has its own set of instruction codes so each machine work ononly one type of computer.Its very laborious to write programs in machine codes. Programs in machine codeare also difficult to decode and modify.There was a time when programmers had to write programs in machine language.Now programmers can use programmiong language.We will look into programming languages next.TYPES OF PROGRAMMING LANGUAGE:We can write a program in a programing language and then translate it into a machine language look at the simple program written in a programming language called BASIC .This program tells the computer to find the area of a square and display the answer on the screen10 Rem Calculate The area of square20 Let side = 1230 AREA =Side * Side40 Print AREAAs you can see .the program statemnet are easier to read , unlike the machine code .A program written in any one of the programming languages is called the source code,The source code has to be translate to machine code before it can be executed. We need a computer translator for this purpose.The machine code is save as an executable file.The executable program file is called the object code.A COMPUTER TRANSLATOR:A computer translator is yet another program. Its function is like that of a human tanslator.Ahuman translator orinterpreter who knows both English and Urdu can help a Pakistani and an Englishman to converse.TYPES OF COMPUTER TRANSLATORS:There are two types of computer translators :InterpretersCompilersINTERPRETERS:An interpreter is a program that translates and executes each source code statment before translating and executing the next statment.COMPILERSCompiler is a program that translate all the source code statment before it executes the program.
