MACHINE CODES Meaning and
Definition
-
Machine codes, also known as machine language or machine instructions, refer to the lowest level of instructions that can be executed directly by the central processing unit (CPU) of a computer. These codes are represented as binary numbers, typically comprised of ones and zeros, which can only be understood and executed by the machine hardware.
Machine code instructions are specific to the computer architecture and vary from one computer system to another. Each individual instruction corresponds to a particular operation that the CPU can perform, such as arithmetic calculations, data movement, branching, and logical operations. These instructions are executed sequentially to carry out complex tasks.
As machine codes are written in binary, they are not easily readable or understandable by humans. However, they serve as the direct interface between the hardware and the software running on a computer. Programmers utilize assembly languages, which provide a more human-readable representation of machine codes, to write programs at a lower level than high-level programming languages.
Machine codes offer a high level of control over the computer hardware, enabling programmers to optimize performance and efficiency. While they require expertise in computer architecture and specific instruction sets, they allow for direct manipulation of the hardware resources.
Overall, machine codes are fundamental to the execution of programs on a computer, as they are the most basic level of instructions that the CPU can directly process.

Etymology of MACHINE CODES
The word "machine code" has its etymology derived from the combination of "machine" and "code".
1. Machine: The term "machine" comes from the Latin word "machina", which referred to a device or contrivance. It later evolved to mean mechanical systems or devices. In the context of computing, a machine typically refers to a computer or an electronic device capable of performing various operations.
2. Code: The term "code" comes from the Latin word "codex", which originally referred to a block of wood, a book, or a tablet. In computing, "code" refers to a set of instructions or rules that are programmed to execute specific tasks. It is a fundamental concept in programming and computer science.
Combining these two terms, "machine code" refers to a specific set of instructions or rules written in numerical form that a computer can directly understand and execute.
