Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its previous state. For example, an instruction may change the value stored in a particular storage location within the computer—an effect that’s not directly observable to the consumer. An instruction may invoke one of many enter or output operations, for example, displaying some textual content on a pc display screen, causing state adjustments that must be visible to the user. The processor executes the instructions in the order they are supplied, until it’s instructed to “bounce” to a unique instruction or is interrupted by the operating system.
