Explain Assembly Language
This is a family of low-level language for programming computers, microprocessors, microcontrollers etc. They implement a symbolic sign of the numeric machine codes and other constants required to program a specific CPU architecture. This representation is generally defined by the hardware manufacturer, and is relies on abbreviations (called mnemonic) that assist the programmer remember individual instruction, register and so on. Assembly language programming is writing machine instructions in mnemonic form by using an assembler to transform these mnemonics into actual processor instructions and related data.
