Ohjelmointikäskyset, often translated as programming instructions or commands, are the fundamental building blocks of computer programs. They represent the actions that a computer can perform and are written in a specific programming language. Each instruction tells the computer to do something specific, such as moving data, performing a calculation, or making a decision. The sequence in which these instructions are executed determines the overall behavior of the program.

There are many types of programming instructions, each serving a distinct purpose. Arithmetic instructions perform mathematical operations like addition, subtraction, multiplication, and division. Logic instructions enable the program to make decisions based on comparisons, such as checking if a value is greater than another. Data movement instructions are used to copy or transfer information between different memory locations or registers within the computer. Control flow instructions, like loops and conditional statements, dictate the order in which instructions are executed, allowing for repetitive tasks or branching based on specific conditions.

The specific syntax and set of available instructions vary significantly between different programming languages, from low-level assembly languages that closely map to the computer's hardware to high-level languages that offer more abstract and human-readable commands. Understanding these basic instructions is crucial for anyone learning to program, as they form the foundation upon which all software is built. Programmers combine these simple instructions in intricate ways to create complex applications that perform a vast array of tasks.
