binäärikäskyt

Binary commands, or binäärikäskyt in Finnish, refer to the fundamental instructions that a computer's central processing unit (CPU) can directly understand and execute. These commands are represented in binary code, a series of 0s and 1s, which is the native language of all digital systems.

Each binary command corresponds to a specific, simple operation. These operations can include arithmetic calculations like addition or subtraction, logical operations such as AND or OR, data movement between memory and registers, or control flow instructions like branching to a different part of the program. The exact set of binary commands a CPU can process is defined by its instruction set architecture (ISA).

When a program is written in a high-level programming language like Python or Java, it must be translated into machine code, which consists of these binary commands. This translation is performed by compilers or interpreters. The CPU then fetches these binary commands from memory, decodes them to determine the intended operation, and executes the corresponding action. Understanding binary commands is crucial for comprehending how computers operate at their lowest level.
