Definitions
- Referring to a code that represents an operation in computer programming. - Talking about a binary code that is used to execute instructions in a computer's central processing unit (CPU). - Describing a low-level code that is specific to a particular computer architecture or processor.
- Referring to a command or set of commands that tells a computer what to do. - Talking about a statement in a computer program that performs a specific task. - Describing a high-level code that is written in a programming language and can be executed by a computer.
List of Similarities
- 1Both are related to computer programming.
- 2Both involve executing tasks on a computer.
- 3Both are essential components of a computer program.
- 4Both are used to control the behavior of a computer.
- 5Both are necessary for a computer to perform operations.
What is the difference?
- 1Level: Opcode is a low-level code that is specific to a particular computer architecture or processor, while instruction is a higher-level code that is written in a programming language.
- 2Function: Opcode represents a specific operation that a computer can perform, while instruction is a set of commands that tell a computer what to do.
- 3Representation: Opcode is represented in binary code, while instruction is written in a programming language.
- 4Usage: Opcode is typically used by computer hardware, while instruction is used by software.
- 5Complexity: Opcode is more complex and difficult to understand than instruction, which is written in a more human-readable format.
Remember this!
Opcode and instruction are both related to computer programming and are essential components of a computer program. However, the difference between them lies in their level, function, representation, usage, and complexity. Opcode is a low-level binary code that represents a specific operation that a computer can perform, while instruction is a higher-level set of commands that tell a computer what to do and is written in a programming language.
