Assembly language is used to write programs using the instruction set for a particular processor/controller.(example : 8051 or 8086 or MIPS).

  • It is confined to a particular machine, it involves symbolic representation of the binary machine codes and other constants needed to program a given CPU architecture.

Assembly Language require an ASSEMBLER to convert the assembly code to machine level code(HEX CODE)

High Level Language require a Compiler to convert into ASSEMBLY THEN machine level code.(Now-a-days compilers are smart enough to generate the machine code directly)

To write assembly code it is necessary to know the architecture of the processor or controller.

To write an High Level Program it is not neccessay to know the architecture completly.

Assembly language is not protable.

High Level Language is Portable.

Answer--Assembly language :-

A programming language that is once removed from a computer's machine language. Machine languages consist entirely of numbers and are almost impossible for humans to read and write. Assembly languages have the same structure and set of commands as machine languages, but they enable a programmer to use names instead of numbers.

Each type of CPU has its own machine language and assembly language, so an assembly language program written for one type of CPU won't run on another. In the early days of programming, all programs were written in assembly language. Now, most programs are written in a high-level language such as FORTRAN or C. Programmers still use assembly language when speed is essential or when they need to perform an operation that isn't possible in a high-level language.

High-level language:-

  • A high level language hides the micro abstractions such as set of command required to be performed by the processors such as CPU. Java and C++ are all high level languages.
  • Java, C++ : all easy to write non-binary languages
  • Example : (i=10, i<10,i++)
  • It is not confined to particular machine.

-JP Morgan

A programming language such as C, FORTRAN, or Pascal that enables a programmer to write programs that are more or less independent of a particular type of computer. Such languages are considered high-level because they are closer to human languages and further from machine languages. In contrast, assembly languages are considered low-level because they are very close to machine languages.

The main advantage of high-level languages over low-level languages is that they are easier to read, write, and maintain. Ultimately, programs written in a high-level language must be translated into machine language by a compiler or interpreter.

The first high-level programming languages were designed in the 1950s. Now there are dozens of different languages, including Ada, Algol, BASIC, COBOL, C, C++, FORTRAN, LISP, Pascal, and Prolog.

An assembly language is where each statement corresponds to one machine instruction. A high level language is where each statement corresponds to more than one, sometimes many, machine instructions.

Difference between HTML and assembly language?

HTML : Hypertext Markup Language is a scripting language used to write websites. Assembly language is a programming language (aka ASM). It uses memory registers like EAX, ECX to hold values and commands like JMP, ADD, MOV to alter those values. Assembly language is very close to machine language and very abstract to the untrained eye. In short, they are nothing a like, and share no similarities.


What is compiler and assembler?

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.


What are the differences between assembly and high-level language c plus plus?

Assembly language is a procedural language with a low-level of abstraction between the source code and the resulting binary code. Assembly language is entirely machine specific, and the onus is therefore upon the programmer to code specifically for that machine. The code cannot be transferred and assembled on a different architecture -- it must be re-written in its entirety. High-level languages such as C++ have a high level of abstraction between the source code and the resulting binary code, with a high degree of separation between the source and the machine. This abstraction renders the source code far more portable than low-level languages as the onus is now upon the compiler to produce the machine specific code, not the programmer. C++ utilises a combination of structured and object-oriented programming to achieve this abstraction, allowing the programmer to create highly robust code that is not only easier to read, but easier to maintain, regardless of its complexity.

Why do you need assembly language?

Assembly language is more human-readable than machine language. Generally, statements in assembly language are written using short codes for the instruction and arguments, such as "MOV $12 SP", as opposed to machine language, where everything is written as numbers. Assembly language can have comments and macros as well, to ease programming and understanding. Generally, programs called "assemblers" transform assembly language to machine language. This is a relatively straightforward process, there being a clear 1-to-1 transformation between assembly and machine language. This is as opposed to compilers, which do a complicated transformation between high-level language and assembly. -------------------------------------------------------------------- ASSEMBLY is the key word to define the difference between Machine Language and Assembly. . Assembly language assembles steps of MACHINE CODE into SUB-ROUTINES defined by simple text words: Such as: the assembly command 'ADD' may represents 20-30 machine commands.

What are the key differences between assembly language and programming language?

Assembly language is a low-level programming language that uses mnemonic codes to represent machine instructions directly. It is specific to a particular computer architecture and is closer to the hardware. On the other hand, a programming language is a high-level language that uses English-like syntax and is more abstract, making it easier for programmers to write and understand code. Programming languages are not tied to a specific computer architecture and are typically more portable and easier to maintain than assembly language.

Why is assembly language reffered to as low level language?

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.
