📺 This is a 6 video series on x86 Assembly Crash Course and in this video (part 1/6 of x86 Assembly Crash series), you'll learn:
What is a register and why it matters in x86
Integer registers in the IA-32 architecture
Differences between memory and registers
Assembly data types (byte, word, double-word, etc.)
The three basic types of assembly instructions
Operand combinations with mov instruction
Differences between AT&T and Intel syntax
Control flow and memory addressing in assembly
Whether you're new to systems programming or preparing for reverse engineering, this tutorial provides hands-on insights into the x86 Instruction Set Architecture (ISA) and the GNU assembler (GAS).
Understanding syntax differences between Intel (commonly used in Windows) and AT&T (used in Linux, UNIX) helps eliminate confusion and gives you flexibility across platforms.
