Maskinspråksinstrukser

Maskinspråksinstrukser, often referred to as machine code instructions, form the most basic level of programming language understood directly by a computer's central processing unit (CPU). These instructions are sequences of binary digits (0s and 1s) that the CPU can execute without any translation or interpretation. Each instruction corresponds to a specific operation, such as adding two numbers, moving data between memory locations, or controlling the flow of program execution.

The set of all possible machine code instructions that a particular CPU can perform is called its instruction set architecture (ISA). Different CPU architectures, like x86, ARM, or RISC-V, have their own distinct ISAs. This means that machine code written for one architecture will not run on another without modification or emulation.

Writing directly in machine code is extremely complex and time-consuming for humans. Therefore, programmers typically use higher-level programming languages such as C, Python, or Java. These languages are then translated into machine code by compilers or interpreters. Assembler is a low-level programming language that uses mnemonics to represent machine code instructions, making it slightly more human-readable than raw binary. An assembler then converts these mnemonics into their corresponding machine code. Understanding machine code is fundamental to comprehending how computers operate at their most primitive level and is crucial for fields like computer architecture, operating systems development, and embedded systems programming.
