In computer programming , machine code , consisting of machine language instructions , is a low-level programming language used to directly control a computer's central processing unit CPU. Each instruction causes the CPU to perform a very specific task, such as a load, a store, a jump , or an arithmetic logic unit ALU operation on one or more units of data in the CPU's registers or memory. Machine code is a strictly numerical language which is intended to run as fast as possible, and it may be regarded as the lowest-level representation of a compiled or assembled computer program or as a primitive and hardware -dependent programming language.

Machine code

A programming language defines a set of instructions that are compiled together to perform a specific task by the CPU Central Processing Unit. Each programming language contains a unique set of keywords and syntax, which are used to create a set of instructions.

Thousands of programming languages have been developed till now, but each language has its specific purpose. These languages vary in the level of abstraction they provide from the hardware. Some programming languages provide less or no abstraction while some provide higher abstraction.

Based on the levels of abstraction, they can be classified into two categories:. The image which is given below describes the abstraction level from hardware. As we can observe from the below image that the machine language provides no abstraction, assembly language provides less abstraction whereas high-level language provides a higher level of abstraction.

The low-level language is a programming language that provides no abstraction from the hardware, and it is represented in 0 or 1 forms, which are the machine instructions. The languages that come under this category are the Machine level language and Assembly language. The machine-level language is a language that consists of a set of instructions that are in the binary form 0 or 1. As we know that computers can understand only machine instructions, which are in binary digits, i.

Creating a program in a machine-level language is a very difficult task as it is not easy for the programmers to write the program in machine instructions. It is error-prone as it is not easy to understand, and its maintenance is also very high. A machine-level language is not portable as each computer has its machine instructions, so if we write a program in one computer will no longer be valid in another computer.

The different processor architectures use different machine codes, for example, a PowerPC processor contains RISC architecture, which requires different code than intel x86 processor, which has a CISC architecture.

The assembly language contains some human-readable commands such as mov, add, sub, etc. The problems which we were facing in machine-level language are reduced to some extent by using an extended form of machine-level language known as assembly language. Since assembly language instructions are written in English words like mov, add, sub, so it is easier to write and understand. As we know that computers can only understand the machine-level instructions, so we require a translator that converts the assembly code into machine code.

The translator used for translating the code is known as an assembler. The assembly language code is not portable because the data is stored in computer registers, and the computer has to know the different sets of registers. The assembly code is not faster than machine code because the assembly language comes above the machine language in the hierarchy, so it means that assembly language has some abstraction from the hardware while machine language has zero abstraction.

The high-level language is a programming language that allows a programmer to write the programs which are independent of a particular type of computer. The high-level languages are considered as high-level because they are closer to human languages than machine-level languages. When writing a program in a high-level language, then the whole attention needs to be paid to the logic of the problem.

Differences between Machine-Level language and Assembly language The following are the differences between machine-level language and assembly language: Machine-level language Assembly language The machine-level language comes at the lowest level in the hierarchy, so it has zero abstraction level from the hardware. The assembly language comes above the machine language means that it has less abstraction level from the hardware. The assembly language is written in simple English language, so it is easily understandable by the users.

It is a machine-friendly language, i. It is a user-friendly language as this language is written in simple English words, which can be easily understood by humans.

Difference Between Machine Language and Assembly Language

A programming language defines a set of instructions that are compiled together to perform a specific task by the CPU Central Processing Unit. Each programming language contains a unique set of keywords and syntax, which are used to create a set of instructions. Thousands of programming languages have been developed till now, but each language has its specific purpose. These languages vary in the level of abstraction they provide from the hardware. Some programming languages provide less or no abstraction while some provide higher abstraction.


Assembly language is the more than low level and less than high-level language so it is intermediary language. Assembly languages use.


High-level programming language

Therefore, those programs should be converted to computer understandable machine language. Machine Language varies from platform. Assembly language follows a syntax similar to the English language.

Programming languages allow humans to create instructions for a computer to perform tasks. There are three categories of programming languages such as High-level programming languages, Assembly language, and Machine language. High-level programming languages are easier for humans to understand.

Assembly Language vs Machine Language

Difference between Machine Language and Assembly Language

Programming languages are used for creating instructions to make computers perform specific tasks. These languages can be categorized as machine language, high-level programming language, and assembly language. Through this article, we aim to make our readers gain more knowledge about the definitions of machine language and assembly language, the difference between assembly language and machine language, and their key features and functionality. The conversion of a high-level language to machine language takes place by using an interpreter or compiler. The assembly language definition states that it acts as the intermediate language between machine language and high-level programming languages.

The lowest-level programming language except for computers that utilize programmable microcode Machine languages are the only languages understood by computers. While easily understood by computers, machine languages are almost impossible for humans to use because they consist entirely of numbers. Programmers, therefore, use either a high-level programming language or an assembly language.

What is a programming language?

By Priya Pedamkar. In this article, we will discuss in detail about assembly language vs machine language. Machine language is a language that has a binary form. It can be directly executed by a computer. The programming language is a set of instructions, in order to make a computer understand to perform a specific task or create an algorithm.

The main difference between machine code and assembly language is that the machine code is a language that consists of binaries that can be directly executed by a computer while an assembly language is a low-level programming language that requires a software called an assembler to convert it into machine code. Programmers write computer programs using programming languages. A program is a set of instructions to perform a specific task.
