What Is an Machine Language?
Machine language, or machine code, is a low-level language comprised of binarydigits (ones and zeros). High- level language, such as Swift must be complied into machine language before the code is run on a computer.
Since computers are digital devices, they only recognize binary data. Every program, video, image, and character text is represented in binary. This binary data, or machine code, is processed as input by the CPU. The resulting output sent to the operating system an Application, which displays the data visually. For example, the ASCII value for the letter "A" is 01000001 in machine code, but this data is displayed as "A" on the screen. An image may have thousands or even millions of binary values that determine the color of each pixel.
While machine code is comprised of 1s and 0s, different PROCESSOR ARCHITECTURE different machine code. For example, a PowerPC processor, which has a RISC architecture, requires different code than an Intel X86 processor, which has a CISC architecture. A Compiler must compile high-level source code the correct processor architecture in order for a program to run correctly.
What Is an Assembly Language?
An assembly language is a type of low-level programming language that is intended to communicate directly with a computer’s hardware. Unlike machine language, which consists of binary and hexadecimal characters, assembly languages are designed to be readable by humans.
Low-level programming languages such as assembly language are a necessary bridge between the underlying hardware of a computer and the higher-level programming languages—such as Python or JavaScript—in which modern software programs are written.
