Assembly

An assembly language is a low-level machine language that uses symbolic instructions rather than raw binary coding to communicate directly with a computer's hardware, making it easier for humans to read.

Unlike high-level programming languages that tend to restrict direct access to your system, an assembly language offers direct access to the system's architecture, allowing full control over the system, processor, memory and other hardware components inside the system.

Each assembly language is specific to an architecture, those include but are not limited to: x86, ARM or RISC-V.

The language uses something called "mnemonics", which are short textual codes that represent specific machine code instructions.

For example, instead of using 10110000, a programmer might write MOV AL, 0 to perform the same operation.

An assembly language is very fast, but won't get you anywhere due to it's complexity and lack of features. One might be more interested to look into something like C or C++ for that kind of fast, optimized language.
