Assembly Language
Assembly language is a low-level programming language, one step away from machine language (binary code that computers understand). Each assembly language is specific to a particular computer architecture, unlike high-level languages like Python or Java which are generally portable across multiple systems.
Programming in Assembly is a bit like doing maths in Roman numerals. It's possible, but not as easy as using a high-level language. So, why do we still talk about it? Why is it important? Here are a few reasons:
1️⃣ Efficiency and Speed: Assembly provides control over the system's resources, allowing the creation of fast and memory-efficient applications. For tasks where every clock cycle counts, Assembly is a great choice.
2️⃣ Hardware Manipulation: Assembly allows direct manipulation of the hardware, making it perfect for system-level programming like creating device drivers.
3️⃣ Understanding Underlying Mechanics: Assembly offers insights into how the CPU works, an understanding that can help even when programming in high-level languages.
Writing in Assembly involves defining CPU instructions, such as MOV (move), ADD, SUB, MUL (multiply), DIV (divide), and JMP (jump), just to name a few. These instructions perform basic operations in the CPU and are combined to create complex programs.
