Types of Computer Programming Languages

There are basically two types of computer programming languages given below:

1. 
   Low level language
   
2. 
   High level language
   

Low Level Languages

The programming languages that are very close to machine code (0s and 1s) are called low-level programming languages.
The program instructions written in these languages are in binary form.
The examples of low-level languages are:

• 
  machine language
  
• 
  assembly language
  

Machine Language

The instructions in binary form, which can be directly understood by the computer (CPU) without translating them, is called a machine language or machine code.
Machine language is also known as first generation of programming language. Machine language is the fundamental language of the computer and the program instructions in this language is in the binary form (that is 0's and 1's).
This language is different for different computers.
It is not easy to learn the machine language.

Advantage of Machine Language

The only advantage of machine language is that the program of machine language runs very fast because no translation program is required for the CPU.

Disadvantage of Machine Language

Here are some of the main disadvantages of machine languages:

• 
  Machine Dependent - the internal design of every computer is different from every other type of computer, machine language also differs from one computer to another. Hence, after becoming proficient in the machine language of one type of computer, if a company decides to change to another type, then its programmer will have to learn a new machine language and would have to rewrite all existing program.
  
• 
  Difficult to Modify - it is difficult to correct or modify this language. Checking machine instructions to locate errors is very difficult and time consuming.
