As will become obvious, the focus of this textbook is on writing system code, the interaction of that code with the ISA of the target machine, and on understanding the functioning of the target machine at a very deep level. Course Objectives Learning Outcomes One of the better ways to explain this textbook is to state the learning objectives for the course for which this text has been written.
Why is learning assembly language still important? An assembly languagealso known as an assembler language, is a low-level programming language.
Therefore, different machines have different assembly languages. This type of language makes use of symbols to represent an operation or instruction.
Hence, it is also often known as symbolic machine code. These days, assembly language makes it possible to manipulate hardware directly, address critical issues concerning performance and also provide access to special instructions for processors.
Uses of assembly language include coding device drivers, real-time systems, low-level embedded systems, boot codes, reverse engineering and more. The following are some of the reasons why learning assembly language is still important and relevant.
Here, you can write code to access the registers and even deal with memory addresses directly for retrieving values and pointers.
So, if you are writing a program that has a great algorithmyou are going to benefit greatly. This is mainly because assembly language is the gateway to optimization in speed, thereby offering great efficiency and performance. So, in this case the best option is to write some code in assembly language and see how the processor and the memory work.
However, one thing to keep in mind is that assembly language is symbolic, so it may appear cryptic. Furthermore, the source code in assembly language is always larger than that of a high-level language.
However, putting in time and effort to master it can benefit one greatly in terms of understanding. However, since every section of binary caters to a certain meaning, it can be somewhat easy to comprehend. Assembly language is transparent When compared to high-level languages, which are mostly in the form of abstract data types, assembly language is bare and transparent.
This is largely since it has a small number of operations. So, this is very helpful for algorithm analysis, consisting of semantics and flow of control. It also makes it easier for debuggingas it is less complex. Overall, there is less overhead as compared to high-level languages.Chapter 1 – Why Study Assembly Language?
This is a textbook for a course in assembly language. More specifically it is a course that covers an older variant (IBM System/ Assembler Language) of the assembly language of the IBM mainframe series of computers from the System/ of the ’s to the Z–Series of the present day.

As assembly is at the root (well, close to the root) of all languages, I for one say that it is worthwhile to learn assembly. Then again, it's worthwhile to learn a functional programming language, logic programming, scripting languages, math-based languages.
Assembly is far from dead. One other reason for learning assembly language is to understand how a buffer overflow vulnerability works. It is still one of the most common bugs in the operating system or library code according to OSWAP and SANS.
Made in Wisconsin. Maybe it's time to rethink your relationship with assembly partners overseas. Fuel cost, language barriers and rising labor costs all contribute to profit erosion, but there is another option.
Why Study Assembly language? There is good news and bad news about studying assembly language programming. The bad news is that it takes too much effort to write applications in assembly language.
