a.
Program Plan Intro
Instructions in Vole machine language:
Computer can understand only machine language, so the instruction must be given in vole machine language. It is an encoded language. The instructions are encoded by using total 16-bits that is also represented by hexadecimal digits. Instructions in vole machine consist of op-code and operation field of the register. First 4 bits are called the op-code and operation field has last 12 bits.
