Types of Programming languages - Low level languages - Machine language - Assembly language

Low level languages

Low level languages

• These languages are near to computer hardware and far from human languages. 
• Writing a program in low level languages requires a deep knowledge of internal structure of computer hardware. 

Two types of low level languages. 

1. Machine language. 
2. Assembly language.

Machine language: 

• Instructions written in binary form. 
• Only language directly understood by computer. 
• Also known as first generation language.

Assembly language:

• One step higher than machine language. 
• Uses symbols instead of binary codes. 
• Also called symbolic language. 
• It is second generation language.
