What is Low-Level Language?

Hello friends, today we are going to know what is the low level language in computer?

If you are learning computer programming, then this question must have come many times in the mind of many of you that what is this Low-level language?

In the post below, you will learn about Low-level language with examples. Along with this, we will also learn about the advantages and disadvantages of Low-level language.

What is low-level language in computer?

Low-level language is such a programming language in which all the basic instructions are written to run the computer. Low-level language can be easily understood by a computer.

Low-level language is the exact opposite of high-level language. Because high level language is used by programmers to create different types of software. Whereas Low-level languages are coded and cannot be read or understood by humans.

The computer's processor understands only binary code, ie '0' and '1' and this language is made by mixing all these things so that the computer can understand it easily. A program made from low-level language executes very fast and provides output very quickly.

It is used first in making drivers of any kind of device and in programs of machine learning because it has the ability to directly control computer hardware. Low-level language is considered a very difficult language as compared to high level language.

Low-Level Language Examples (Examples of Low Level Language): –

1. machine language

2. assembly language

1. Machine language

The name of machine language itself suggests that this language is directly understood and supported by machines. The computer cannot take instructions in the language of us humans, so machine language was created to instruct and communicate with the computer.

Basically, 0 and 1 are used in machine language, which our computer understands very easily. This clearly means that machine language is also written in binary code.

In common language, 0 means OFF and 1 means ON. Machine language is written only in the language of 0 and 1, so it is also considered a very difficult language. Since all the programming is done in 0's and 1's, it is very difficult to find faults in it.

Writing code in machine language is also a big challenge for programmers because writing code in it is not an easy task. To write code in Machine Language, it is also very important to have knowledge of the basic architecture of the computer.

2. Assembly language

We all have read about machine language, how difficult it is, so to overcome this problem, computer scientists created assembly language so that programs written in machine language can also be written easily.

With the help of assembly language, any program can be easily written, read and understood. Programs are written in assembly language with the help of letters, numbers and symbols, so it is very easy to understand and write them.

Assembly language is a language between machine language and high level programming language. Its codes are such that even a common man can easily read and understand such as ADD, SUB, TRAN (Translation), JMP (Jump), etc.

Assembler is a type of software that converts assembly language code into machine language code. Assembler basically works like a translator which translates the code written in one language into the code of another language.

The code which is written in assembly language is called Mnemonic code. Assembler is already provided with the system software in a computer.

Features of Low Level Language

• Programs written in low-level language depend on the machine. So the same code will give different output on different devices.
• There is no need of any kind of Compiler or Interpreter to convert the program written in it into Machine level language. However, assembler software is required to convert the program written in assembly language into machine language.
• To execute a low-level language, much less memory and time is required than a high-level language. However, understanding the programs written in it and finding fault in them is a very complicated task.
• This programming language is mainly used to write programs for devices, Drivers, Operating system, Database, etc., which can directly control the hardware of the computer.

Advantages and Disadvantages of Low-Level Language

Following are the major advantages and disadvantages of low-level language: –

Advantages

• A program written in a low-level language requires much less time and memory than a program written in a high-level language.
• If a computer engineer has to make better use of processor and memory, he can easily do so with the help of this language.
• The code written in this does not require any compiler and interpreter, so it takes much less time to run those codes than the codes written in high level language.
• With the help of this programming language, we can directly manipulate the storage and memory registers of our computer. Along with this, with the help of this programming language, we can also directly access all the hardware of the computer.

Disadvantages

• Programs written in low-level language are machine dependent, so a program written on one machine may give different result or output on another machine.
• In general, this language is very difficult, so writing code in it, finding fault, understanding and maintaining it is a very complicated task.
• Because of all these things, the possibility of error in low-level language programs increases considerably.
• To write code in Low-level Language, a programmer should also have a good knowledge about the computer architecture of that machine, otherwise he will not be able to write a Low-level language program for that computer.

In short – Conclusion

Contrary to its name, low-level language is a very difficult language in which programming is very difficult. However, if someone has to access the computer's memory and hardware, then it is possible only through programs written in low-level language.

If attractive softwares are made through high level language, then low-level language is very important for the basic activities of the computer.

Machine learning is very much discussed in today's world. Even for learning machine learning, it is very important for programmers to have knowledge of this programming language because only through this we can access any hardware of the computer.

To run the computer, very important programs such as Operating System and Device Drivers etc. are made in this programming language. So we can finally say that Low-Level Languages are very important for a computer.
