Final answer:
Computer instructions that can be executed are known as object code, which is processor-specific binary code generated from source or assembly code through a compilation process.
Step-by-step explanation:
Instructions that can be read and acted on by a computer are called object code. Object code is generated after a high-level source code or assembly code written by a programmer is compiled. It consists of a series of instructions that the computer's processor understands and can execute directly. These instructions are typically in binary form and are specific to the architecture of the processor in the computer.
