What is a symbolic machine language?
Assembly language is a symbolic machine language.
Assembly language is any low-level language used for electronic computers, microprocessors, microcontrollers or other programmable devices, also known as symbolic language. In assembly language, mnemonics are used to replace the opcodes of machine instructions, and address symbols or labels are used to replace the addresses of instructions or operands.
In different devices, assembly language corresponds to different machine language instruction sets, which are converted into machine instructions through the assembly process. There is a one-to-one correspondence between a specific assembly language and a specific machine language instruction set, and they are not directly portable between different platforms.
Extended information:
The characteristic of assembly language is that it is easy to be recognized and executed by the computer. Using it for programming can reduce the space occupied, increase the running speed, and Can directly control the hardware.
It plays an irreplaceable and important position when real-time control is required, but assembly language is more complicated and difficult to program and understand, especially when performing data processing or logical operations, its disadvantages are highlighted. .
High-level language is a user-oriented language that can be more accurately understood by programmers. It has strong expressive ability, many functions, high programming efficiency, fast learning speed, and high degree of automation, so it is more popular. .
