Difference Between High-Level Language and Low-Level Language

Programming languages are broadly classified into two types. i.e., low-level languages and high-level languages and there is a big difference between them.

Difference Between High-Level Language and Low-Level Language are:

High-Level LanguagesLow-Level Languages
High-Level Languages are easy to learn and understand.Low-Level Languages are challenging to learn and understand.
They are executed slower than lower level languages because they require a translator program.They execute with high speed.
They allow much more abstraction.They allow little or no abstraction.
They do not provide many facilities at the hardware level.They are very close to the hardware and help to write a program at the hardware level.
For writing programs, hardware knowledge is not required.For writing programs, hardware knowledge is a must.
The programs are easy to modify.Modifying programs is difficult.
A single statement may execute several instructions.The statements can be directly mapped to processor instructions.
BASIC, Perl, Pascal, COBOL, Ruby etc are examples of High-Level Languages.Machine language and Assembly language are Low-Level Languages.
