What computer language is closest to machine instructions?

The computer language closest to machine instructions is assembly language.

Assembly language is a low-level language used for electronic computers, microprocessors, microcontrollers or other programmable devices. It is also called a 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.

Assembly language needs to be translated into machine language by an assembler before it can be recognized by the computer.
