Assembly language: A machine-oriented symbolic programming language, so it is also called symbolic language. Unlike machine languages, assembly language uses intuitive, easy-to-remember and understand English words or abbreviation symbols to represent instructions and data variables, for example, MOV AX, VAL is a transmission instruction, where MOV is the instruction opcode, AX is a register in the CPU, VAL is a symbolic representation of a variable, and the instruction represents the transmission of the value of the variable VAL to AX. So assembly instructions are also called symbolic instructions, and these symbols are called mnemonics. The assembly instruction set and the directive set and the rules for their use are collectively referred to as assembly language. Assembly language is known as a second-generation language.
