suoritinkäskyjä

Suoritinkäskyjä, also known as processor instructions or machine code instructions, are the fundamental commands that a central processing unit (CPU) can execute. They are the lowest-level instructions that a computer's hardware understands. Each instruction typically performs a very basic operation, such as adding two numbers, moving data between memory and the CPU, or comparing values.

These instructions are represented in binary form, making them unintelligible to humans directly. A sequence of these instructions forms a program. Compilers and assemblers translate human-readable source code written in programming languages into these machine-readable suoritinkäskyjä.

The set of all suoritinkäskyjä that a particular CPU can execute is known as its instruction set architecture (ISA). Different CPU architectures, like x86 (common in PCs) and ARM (common in mobile devices), have different ISAs, meaning they can execute different sets of instructions. Understanding suoritinkäskyjä is crucial for low-level programming, compiler design, and understanding how computer hardware functions.
