   Assembly language

The assembly language is also called 2GL. This language is not directly processed by microprocessor. A translator namely Assembler converts it into machine language.  That machine code is directly understood by microprocessor A translator namely are close to a one to one correspondence between symbolic instructor's instructions and machine code Writing program in assembly language is typical than writing program in high level language because program needs to have detail knowledge of the processor.  

 Main features of assembly languages are the following: 

• Allows symbolic designation of memory locations.
• Is very fast. The critical sections of programs written in higher level languages can be written in assembly to speed up sections.
• Changes should first be made in the source code of assembly language and then reassemble it to create a new object program.
• Gives direct access to key machine features, such as device drives and machine control.
