Machine Language

Machine language or machine code is a low-level language made up of binary digits (ie ones and zeros). High-level languages, such as Swift and C ++ must be compiled in machine language before running that code in the computer.

Since computers are digital devices, they can easily identify binary data . Each program, video, image, and character of text are represented in binary. In this, binary data, or machine code, is processed by the CPU at the input level . The resulting output is then sent to the operating system or an application, which displays that data visually.

For example, Letter ” A ” is the ASCII value 01000001 in machine code, but data on “the Display A on Screen as”. At the same time, an image has millions of millions of binary values ​​which determines what the color of each pixel is.

By the way, machine code is made up of 1s and 0s, so different processor architectures use different machine code. For example, a PowerPC processor, which has a RISC architecture, requires a different type of code than an Intel x86 processor, which requires a CISC architecture. A compiler must compile high-level source code with the correct processor architecture so that a program can run correctly.

Machine Language vs Assembly Language

Machine language and assembly language are both low-level languages, but machine code is below assembly in the hierarchy of computer languages. Assembly language includes human-readable commands, such as mov, add, and sub, whereas machine language has no words or letters of any kind.

Some developers manually write assembly language so that they optimize a program, but they do not write machine code. Only developers who write code for software compilers have to worry about machine language.

Although the machine code is technically composed of binary data, it is represented in hexadecimal values. For example, the letter ” Z ,” which is 01011010 in binary, is displayed there as hexadecimal code as 5A.
