While most software today is written in high-level languages, understanding assembly provides powerful and unique insights into the fundamental workings of a computer. It bridges the gap between the software you write and the hardware that runs it.

• Deeper System Understanding Learning assembly reveals the inner mechanics of computing. You will gain awareness of how your programs interface with the Operating System (OS), processor, and BIOS, and see exactly how data is represented and stored in memory.
• Peak Performance and Control Assembly language code requires less memory and execution time than code written in high-level languages. This efficiency makes it the perfect choice for time-critical jobs where every microsecond and every byte of memory counts.
• Direct Hardware Interaction Assembly gives you unparalleled access to the hardware. It allows you to perform hardware-specific, complex jobs more easily, such as writing specialized programs called interrupt service routines that respond directly to hardware events.

Now that you understand why learning assembly is so valuable, let’s look at how an assembly program is structured.
