From the dawn of human society to the point in time that we are in, we have developed a lot. And our technology has developed with us.
We are in a multilinguistic world with different languages, but unfortunately, our computer is not. But still, we can talk to them thanks to the assembly language.
In this article, we will see the advantages of assembly languages and how, because of it, smartphones have become an integrated part of our lives.
Programming Language:-
A professional language used in computing made up of a bunch of instructions executed to have different outcomes is called Programming language, which is a part of computer programming.
The programming language based on abstraction is divided into two levels: High and Low, and is carried out by the CPU(Central Processing Unit).
The low-level programming language is more machine-oriented than High-level language and is less abstract and not so easy compared to High-level programming language.
There are two types of low-level programming language: Assembly language and Machine code. Although Assembly language and Machine code are both Low-level languages, they have different tasks. Along with these two, a user can opt for high-level programming in computing.
There are many modern programming languages that a user can use and learn, including C, C++, COBOL, Java, Python, Fortran, Ada, Ruby/Ruby on Rails, HTML(HyperText Markup Language), and Pascal.
Machine language:-
Native code is one of the names used for Machine code, a computer programming written in Machine language that is usually the binary language.
It is the lowest level in the hierarchy. Like Assembly language, other programming codes are converted into Machine code so the computer can understand and work on it.
The machine code works on the instruction, which informs the computer of what operation to perform. Every instruction is made from an operation code called opcode and operands, which are memory data and addresses. An instruction list is a set of opcodes available on the computers.
A computer does not need any compiler or interpreters to execute Machine language as it is already in binary form.
Compiler:-
A compiler is a program builder that converts one programming language to another, like decoding the first programming language and then encoding it into other programming languages. A compiler is usually used in converting Assembly language into Machine code.
Assembly Language:-
Assembly language is one such low-level programming language that is sometimes called Symbolic Machine Code.
Assembly language is called Assembler language, and ASM in short form and functions on the computer architecture. It can calculate expressions that take many users’ time in machine code.
Users can ask the computer to work on any task using Assembly language and act differently on different CPUs. Assembly language is very easy to use as it is a language that does not use binary or in simple words, numbers but use English words that we use in daily life.
It is easy to use Assembly language because it uses Mnemonics( M is silent), which is a short word used for each low-level instruction, such as Mov indicating moving data from a place to another, Adds, which means adding data, for identifying each architectural register which is the location address given to a computer’s processor that can be easily accessed.
In the assembly language, the user is not needed to remember all the number’s digits, making it easier to read than Machine code.
As we know, computers can not understand anything other than their original official language, which is the binary language i.e. 0 and 1. Still, it is pretty easy to convert the assembly language into Machine code by turning the words in the language into numbers.
We use an assembler program to convert the Assembly language into binary and make it understandable for the computer.
Assembler:-
The process of converting Assembly code into Machine code through an assembler is called assembly.
Assembler is a program that is used to convert Assembly low-level codes into machine code to make the computer understand the language, and many Assemblers can provide a system to enhance the development of the program, control the assembly process, and also provide treatment against debugging that are the procedures to find any bug in the system, software or programs.
Why use Assembly language and not Machine code?
Assembly language and Machine code are low-level programming languages but are entirely different in their function.
Assembly language is a low-level programming language that uses instruction in the language we use daily, that is, English. In contrast, Machine code uses a binary form of language that can be understood by the computer.
The computer can not understand any language other than Binary, so Assembly code is converted into Machine code by a program called Assembler, and a user, instead of Assembler, can also use Compiler, which is also a program used to convert high-level programming language into Machine code.
Assembly language is a middle layer between the high level, whereas Machine language is the lowest level out of the three, it is easy to understand a language you already know rather than experimenting with 0 and 1s, and the user does not have to undergo a long calculation to achieve the data.
Uses of Assembly language:-
Assembly language is preferred more than Machine language and is used widely as it reduces the most time-consuming first-generation computer programming vulnerable to errors. It saves a user time.
As technology is updating day by day, many things are not used as much as it was used before due to the development of new technology, such as high-level programming levels such as pythons, C, and C++, but still, Assembly language is used for direct hardware manipulation, access to specialized processor instructions, and to tackle any serious performance issues and is mostly used in low level embedded system, device driver and realtime system.
Advantages of Assembly language
Everything has pros and cons, and Assembly language is nonetheless the same. Here are some of the well-known advantages of assembly language.
A programmer, if using Assembly language, can have complete control over their device’s system and its function, which Machine language cannot provide to its users. Learning simple syntax is easier than learning numbers, code, and calculation addresses.
Assembly language uses less time, which helps in speed enhancement, leading to heightened efficiency and performance, and it helps the programmers understand each instruction and process. A programmer should know what she/he is doing.
Assembly Language does not require detecting the operand’s machine address, and the syntax can be represented with a symbol, making it easy to understand the procedures visually.
Even though Assembly language has a fewer number of instructions and operations is still the best programming a person can ask for if they want to learn the algorithm and controlling of it.
Assembly language overall makes the coding simpler and does not make it complicated. As well as provides aid for debugging, meaning searching for any bugs in the system or software and then working against them.
Overall, Assembly language lets the work done more simply rather than complicating it; it needs less memory space proving it is more business-like and is more likely to take less time to execute the task due to faster speed and, for the most part, is hardware-oriented.
In assembly language, programmers can complete the operation quickly to get the output as it requires few instructions.
Nowadays, it is used in very critical jobs and is used in low embedded systems, and keeping tabs on memory location is not needed in it.
A user can create its code and have complete copyright on it, but it is rarely seen that a user creates its code.
Disadvantages of Assembly language
Nothing is perfect in this world, and assembly language is no exception. In the former section, we have discussed the advantages of Assembly language; in this section, we will see the disadvantages of Assembly languages.
Assembly language though is above Machine language it, will still take time to type codes per code to function in an operation and is quite an easy target for bugs, and due to its architecture, it would be hard to detect bugs.
If a beginner is typing the code, it is most likely error-prone, creating a code that can be difficult for the first time.
In the future, it won’t work as a user will not get any output due to its architecture. A user can also learn High-level programming languages as they are machine-independent, and assembly language depends on the machine.
Note: Even a small change in the algorithmic design can completely negate all the existing assembly code, so a user should only take such a risk if they are ready to rewrite all the codes.
