What are the two parts of many machine code and assembly instructions?

• Hexadecimal and Denary

• Opcode and Operand

• Input and Output

• Binary and Decimal

What does an opcode specify in a machine code instruction?

• A memory address

• Instructions that can be executed by a CPU

• A programming language

• A data value

What is an operand in the context of machine code instructions?

• A type of opcode

• A type of translator

• Data manipulated by the CPU according to the given opcode

• A programming method

Why is hexadecimal popular with programmers?

• It is easier to read and understand

• It is newer than binary

• It uses less memory

• It is faster to execute

What numerical systems are used to represent opcode and operand values?
