Assembly Language in 3 minutes

I. Introduction to Assembly Language
- Definition of assembly language as a low-level programming language.
- Purpose: Communication between the programmer and hardware.
II. Historical Perspective
- Initial programming: Directly using zeros, ones, or hexadecimal numbers.
- The cumbersome nature of programming using machine code.
- Introduction of assembly in the 1950s for a more human-readable representation.
- Representation of machine code with codes like `Add`, `Move`, and ‘Jump’.
III. Comparison with High-Level Languages
- Difficulty of assembly in comparison to other programming languages.
- Advent of FORTRAN and COBOL as human-friendly high-level languages.
- Reduced necessity for programmers to learn assembly.
IV. Importance of Learning Assembly
- Value for those focused on performance-critical code.
- Insight into the interaction between software and hardware.
- Instructional importance in computer architecture, OS, and compiler design courses.
- Use in reverse engineering and developing software exploits.
V. Diversity of Assembly Languages
- Specificity of assembly languages to computer chip designs.
- Variation in assembly language based on processor architecture.
- Highlighted assembly languages:
- x86 Assembly for Intel and AMD processors.
- ARM Assembly for ARM processors, prevalent in mobile devices, Macintosh, and embedded systems.
- MIPS Assembly for MIPS processors in embedded systems and past workstations.
VI. Basic Assembly Language Programming
- Illustration of a "Hello, World!" program in x86 Assembly:
- Setup, movement of values, and system calls for text output and program exit.
- Demonstration of a basic addition program:
- Loading, addition, and program termination at a foundational level.
VII. Perspective on Assembly Usage
- Rarity of full-program development in assembly.
- Benefits of learning assembly for comprehensive understanding of computer operations.

What do you need to learn to get a job? Is there a specific language that carries value in the market place. I have a lot of experience working with sap but it's mostly from a user instead of a programmer. I have created configuration for wm but I would enter a ticket to get the programming completed. I would test any changes before they were moved into the live environment. Is it worth learning ABAP? Is there something else that would be more valuable in the market? Thanks

I would suggest you find out what programming languages are used by your company and focus on those. Apart from that choose something that is in the tiobe top 10. Java, C#, Javascript are popular web development languages. C, C++, Go are useful for engineering and embedded software development. Python, R and Matlab for stats and data modeling. Kotlin, Dart and Swift for mobile apps.

@shadsluiter thank you. My company relocated to China. They run sap. I wasn't sure which would be most valuable in the marketplace since I now looking for another job. Thank you for responding.

[@shadsluiter]

The two together make a full processor?
