• Machine Language 
• Assembly Language 
• High-Level Language

1. Machine Language:

• A computer programming language consisting of binary instructions which a computer can respond to directly. 
• The machine language of the computer is normally written as strings of binary 1s and 0s. 
• A machine language instruction normally has a two-part format.

• The first part of an instruction is the operation code, which tells the computer what function to perform. 
• The second part is the operand, which tells the computer where to find or store the data of other instructions, which are to be manipulated.

Advantages:

• A computer can easily understand the Machine language. 
• Machine language instructions are executed directly without any translation. 
• Machine language instructions require very less time for their execution.

Disadvantages:

• Machine language instructions are very difficult to use and understand. 
• Machine language instructions are machine dependent, that means a program written for a particular machine does not execute on another machine. 
• In Machine language, there is more chance for errors and it is very difficult to find errors, debug and modify. 

2. Assembly Language:

• Using alphanumeric mnemonic codes, instead of numeric codes for the instructions in the instruction set. 
• E.g. using ADD instead of numeric 1110 or SUB instead of 1111(binary).

• Using storage locations to be represented in the form of alphanumeric addresses, instead of numeric addresses.
• E.g. the memory location 1000,1001,and 1002 may be represented as FRST,SCND and ANSR.
• Instructions written in assembly language is translated by a language translator called Assembler.

Advantages:

• Writing instructions in assembly language is easier than writing instructions in machine language. 
• Assembly language is more readable compared to Machine language. 
• Easy to understand, find errors and modify. 

Disadvantages:

• Assembly language is specific to a particular machine architecture, that means it is machine dependent. 
• Assembly language needs to be translated into machine language. 
• Assembly level language executes slower compared to machine language. 

High-Level Language:

• The High-level language is simple and easy to understand and it is similar to the English language. 
• High-level languages have enabled the use of computers to solve problems even by non-expert users. This has allowed many users, without any background in computer science and engineering, to become a computer programmer.

Advantages:

• Writing instructions in the high-level language is much easier. 
• High-level language is more readable and understandable. 
• The programs created using high-level language runs on different machines with little change or no change. 
• Easy to understand, create programs, find errors and modify. 

Disadvantages:

• High-level language needs to be translated to machine language. 
• High-level language executes slower compared to assembly and machine languages.
