For SYMBOL INSTRUCTIONS SUCH AS MOVAX AND VAL, THEY ARE RELATIVELY CONCISE AND EASY TO READ, BUT THE COMPUTER DOES NOT RECOGNIZE MNEMES, BUT CAN ONLY RECOGNIZE BINARY ENCODED MACHINE INSTRUCTIONS, SO IT NEEDS TO PASS

For MOV AX, symbolic instructions such as VAL are relatively concise and easy to read, but the computer does not recognize mnemonics, and can only recognize binary-encoded machine instructions, so it is necessary to translate the assembly language source program into a machine language program through a translation program before it can be submitted to the computer for execution. This translation program is called assembler, and this translation process of assembly language source programs is abbreviated as assembly. The advent of assembly language has greatly improved programming conditions and enabled more people to program.

Although programs written in assembly language are easier to understand than machine code, each assembly language instruction corresponds to a machine instruction, so it is not fundamentally different from the machine language, so assembly language is still a low-level machine-oriented language.
