https://simple.wikipedia.org/wiki/OpcodeAn opcode identifies which basic computer operation in the instruction set is to be performed. It is used when writing machine code. It tells the computer to do something. Each machine language instruction typically has both an opcode and operands. The opcode is like a verb in a sentence, and the operands are like the subject in a sentence.

Langage machine — Wikipédia
https://fr.wikipedia.org/wiki/Langage_machineOpcode. Chaque instruction commence par un nombre appelé opcode (ou code opération) qui détermine la nature de l'instruction. Par exemple, pour les ordinateurs d'architecture x86, l'opcode 0x6A (en binaire 01101010) correspond à l'instruction push (ajouter une valeur en haut de la pile).
