Difference between High Level Language and Low Level Language

There are differences between the low level and high level languages but they both are very important for the computer system and application software to function. The machine level language was introduced in the first generation of the computer which can only receive input in ones and zeros then the assembly level language came which can interact with the hardware with the help of mnemonic for the binary codes which made programming much easier than being a tiresome and repetitive task. After the assembly language the high language came such as BASIC and Pascal which were used to create application programs and utility drivers for the computer system from thereon the assembly language handled the hardware aspect and high level language handled software aspect of computer systems.

Difference between High Level Language and Low Level Language

High Level Language Low Level Language
High level language are user friendly language Low level language are machine friendly language
The syntax of high level language include mathematical symbol and natural language  The syntax of low level language include binary codes and mnemonics
The high level language does not requires to know the architecture of CPU The low level language requires to know the architecture of CPU
These languages are highly portable across any computer system These languages are not portable as each system has unique configuration
High level language are commonly used in developing of computer applications and software Low level language are commonly used for interacting with the hardware to perform series of instruction
They are easy to debug as there are various tools to help in writing code and finding error They are not easy to debug and the lack of resources make it harder to handle error
There is no requirements of knowledge about computer hardware is needed  Their is great requirement of knowledge about computer hardware which is needed to write the program
The high level language are not dependent on the hardware to execute their instructions The low level language are dependent on the hardware and its configuration to execute their instruments 
The high level language is slower than the low level language because they use natural language and characters that cannot interact with the CPU and register directly therefore they require interpreters and compiler.  The low level languages are faster than the high level languages as they interact directly with the CPU and register for execution. Also, it does not use classes and libraries as the high level language does which makes it faster.
The high level language are less memory efficient that the low level language because they most of the times execute on run time environment which runs various process concurrently to get optimal result The low level language are more memory efficient because the programmer has to specify the registers to use for the program to run which is not the case in high level language
The high level language because if their natural language syntax makes it more easier to learn The low level language requires good amount of specialization and more time to learn
The high level language exists greater level of abstraction as they are more user oriented  The low level language had lower level of abstraction because of their direct interaction with the hardware
Their are greater resources such as libraries and classes to help program in high level language Their are less resources as they tend to be more hardware specific which makes it more stand alone 
The compiler and interpreter act as the translator in the high level language The assembler act as the translator for the low level language
A single statement can execute many lines of instruction A single statement can execute one instruction at a time
The examples of the high level language includes Java, C, Python, Ruby, PHP, etc The example of the low level language are assembly language(mnemonic codes) and machine level language (binary codes)
