differences between high level and low level language

we explain that high level language is easy for humans to read, write and modify. while low level language is difficult for humans to read, write and modify. the basic difference between high level language and low level language is that high level language is a programmer-friendly language and is simple to maintain. on the other hand, low level language is a machine-friendly language and it is complex to main comparatively.

Key differences between high level and low level language in tabular form:

High level Language Low level language
These languages are easy to learn. These languages are difficult to learn.
These languages are near to human languages. These languages are far from human languages.
It needs a translator. It does not require any translator.
Programs in high level languages are slow in execution. Programs in low level language are fast in execution.
Programs in high level language are easy to modify. Programs in low level languages are difficult to modify.
It does not provide many facilities at the hardware level. Low level languages provide the facility to write programs at the hardware level.
Deep knowledge of hardware is not required to write programs. Deep knowledge of hardware is required to write programs.
These languages are normally used to write application programs. These languages are normally used to write hardware programs.

What is High Level Language? (Explained)

This is a type of programming language that is close to human languages is called high-level language. These languages are very easy to understand. Instructions of these languages are written in English like words such as keyboard, monitor, mouse, LCD’s, etc. That program written in a high language is easier to write and modify. A high-level language is divided into 3 categories:

Procedural language
Object-oriented language
Nonprocedural language

What is low level language? (Explained)

It is a type of programming language which are near to computer hardware and far from human languages. A computer can understand these languages very easily. Writing programs in a low language require a deep knowledge of the internal structure of computer hardware.

Types of low level languages:

  • Machine language
  • Assembly language

what is Machine language:

The main type of language in which instructions are written in binary form is known as machine language. Machine language is the only language that is directly understood by the computer. Machine language is the most fundamental language of the computer.

machine language example:

The programs written in the machine language can be executed very fast by the computer. Those programs written in machine language are machine-dependent. Every computer has its machine language system. Machine language is difficult to understand. Writing and modifying programs in machine language takes a lot of time. This language is also famous as first-generation language.

what is Assembly language?

This language is a low level language. It is one step higher than machine language. Symbols are used instead of binary codes in the assembly language. Those symbols are called mnemonics. For example, sub instruction is used to subtract two numbers.

assembly language example?

It is also famous as a symbolic language. The programs written in assembly language are easier to write and easily modify than machine language. This language is mostly used in writing system software. Assembly language is also famous as second generation language.
