Basically, an instruction is a combination of Flag Bit, Opcode, and Data. Flag Bit can be categorized into whether sign, or un-sign. Opcode is control. Opcode is also known as mnemonic. Opcode can be categorized into ALU oriented, General purpose oriented, Streaming Data oriented, and ... ; Data can be either being inside of Data bits of the instruction, or sometime can be a whole word of bits as Data.

Flag Bit Opcode Data
Sign bit ADD bits
Un-sign bit COPY

Depending on hardware specifications, computing architecture varies. i.e. super computer specification uses not only instruction diagram, but also vector diagram. In addition to instruction diagram and vector diagram, Quantum computer specification uses particle diagram, and etc.
