What are High-Level Languages?
Before knowing about the difference between high-level and low-level languages, let us explore high-level language. A high-level language is easy to read, write, and maintain by the human or programmer. These High-level languages are less memory efficient and these languages are simple to debug. The High-level programming language (HLL) is used for developing user-friendly software programs and websites. A high-level language is further divided into three parts first one is Procedural Oriented Programming (POP) language, the second one is Object-Oriented Programming (OOP) language and the third one is Natural language or human language.
Examples of High-level programming languages are Java, JavaScript, Python, PHP, C#, Objective C, C++, Cobol, Pascal, Perl, FORTRAN, LISP, and Swift programming language.
What are Low-Level Languages?
Low-Level Languages are machine-friendly languages that are quite difficult to understand by human beings but very easy to interpret by machines. The Low-level language is a machine-dependent programming language. The processor runs the low-level programs directly without the compiler or interpreter which is why the programs written in low-level language can be run very fastly. This language is difficult to write, understand and debug due to this person moving toward high-level language. It is a series of bits of 0s and 1s or it performs short instructions like ADD, MOV, etc.
A low-level language is further divided into two parts, the first one is Machine Language and the second one is Assembly language (ASM). Let us now see the difference between high-level and low-level languages in the coming section.
What is the Difference Between High-Level and Low-Level Languages?
As we have seen a brief introduction to high-level and low-level languages. We will now explore the difference between high-level and low-level languages. The major differences between these two languages are explained in the table provided below:
Difference Between High-Level and Low-Level Languages | |
High-Level Languages | Low-Level Languages |
High-Level Languages are human-friendly language that is easy to learn and understand. | Low-Level Languages are quite challenging for humans to learn and understand. |
They are executed at a slower speed as they require a translator program. | This language can execute at high speed. |
These languages allow much more abstraction. | These languages have negligible abstraction. |
These languages have a very low memory efficiency and consume more memory | These languages have a very high memory efficiency and consume less energy. |
These languages are unable to provide many facilities at the hardware level. | These languages are machine friendly and very close to the hardware so it helps to write a program at the hardware level. |
No need for hardware knowledge for writing programs. | Hardware knowledge is necessary for writing programs. |
In these languages, modification of programs is easy for humans. | In this language, modification of programs is quite difficult for humans. |
A single statement in this language may execute several instructions. | The statements in these languages can be directly redirected to processor instructions. |
Programming, these languages are very common and widely used nowadays | For programming, these languages are not very common nowadays. |
Java, JavaScript, Python, PHP, C#, Objective C, C++, Cobol, Pascal, Perl, FORTRAN, LISP, and Swift programming language.are examples of High-Level Languages. | Machine language and Assembly language are the Low-Level Languages. |
