Machine language is the actual bits used to control the processor in the computer, usually viewed as a sequence of hexadecimal numbers (typically bytes). The processor reads these bits in from program memory, and the bits represent "instructions" as to what to do next.
Thus machine language provides a way of entering instructions into a computer (whether through switches, punched tape, or a binary file).
Assembly language is a more human readable view of machine language. Instead of representing the machine language as numbers, the instructions and registers are given names (typically abbreviated words, or mnemonics, eg ld means "load"). Unlike a high level language, assembler is very close to the machine language. The main abstractions (apart from the mnemonics) are the use of labels instead of fixed memory addresses, and comments.
An assembly language program (ie a text file) is translated to machine language by an assembler. A disassemblerperforms the reverse function (although the comments and the names of labels will have been discarded in the assembler process).

Unix was rewritten in the C programming language and not in assembly language. The migration from assembly language to the higher-level language C resulted in much more portable software, requiring only a relatively small amount of machine-dependent code to be replaced when porting Unix to other computing platforms. Unix manages the hardware and the executing processes by the kernel. The kernel is a collection of programs written in C which directly communicate with the hardware. applications communicate to system using kernal. Hence kernal need to be changed for different hardware but user interface remains same.
Modifies and Programmed for general computing purposses.

No. Sorry, you're out of luck there. Operating Systems are complex pieces of software that interact directly with the computers hardware. To interact with a computers hardware through a program, you must use a very low level programming language. What is a low level language? When a computer reads code, it must break it down until it is readable by the machine. The broken down code (aka, low level language or machine code) is a series of ones and zeros. There are a number of low level languages: ASM (Asembly), Machine Code, and C. Why do operating systems need low level languages? In order to communicate with the machine (CPU), the OS needs to be programmed in a low level language. If it was done in a high level language, it wouldn't be able to communicate and another OS would need to break it down for the machine. What about HTML? Where does it fit in? HTML is pretty much the highest-level language there is available. Most OSs can't read HTML directly, and require an Internet browser to read it (ex. Google Chrome, Firefox, or Safari). If you are looking into making an OS, just know a few things: 1. It will take years to build it 2. You must know a low level programming language very well 3. It might be best to start with someone else's OS instead of reinventing the wheel (ex. Linux open source)
Assembly language is a readable way of representing machine language. It consists of mnemonics that can be directly converted to machine language. Assembly language allows easier jump instructions with the usage of labels which gets converted to real addresses after assembling.
Assembly langue is translated into machine language by an assembler.
An Assembler converts assembly language instructions into machine 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
Assembly language is low-level because it has the least amount of abstraction between the source and the resultant machine code. That is, the translation from assembly language to machine code is 1:1. All high-level languages have much higher degrees of abstraction.

Assembly
No, they are not the same. Assembly language uses mnemonic words to REPRESENT machine language; to be able to actually run it, a special program - a so-called assembler - then needs to convert it into machine language.
assembly language uses abbreviation called menmonics.it is a bit easier to write computer programs in assembly language as compared to machine language but still requires skill and experienci.A program called assembler is used to convert an assembly language into machine language.
Machine language refers to pure code (object code) in basic machine format (zeros and ones). Assembler is one step above this type of code and requires compilation before it is of any use to the computer.
Both, compiler and assembler, are software tools which translate instructions written in a programming language into executable machine code. (Both will typically require additional tools, such as a linker, in the process.) An assembler recognizes a machine-specific assembly language. This is a low-level language with a one-to-one relationship between language (assembly) instructions and machine code instructions. A compiler recognizes a generally machine-independent language such as the C programming language. These are higher level languages compared to the assembly languages, generally offering a one-to-many relationship between language instructions and expressions, and the resulting machine code instructions.
