enkärnig

Enkärnig is a Swedish term that translates to "single-core" in English. It refers to a processor or a CPU that contains only one processing unit. In the context of computing, a single-core processor can execute only one task at a time. This means that if multiple applications are running, the single core must switch between them rapidly to give the illusion of multitasking. Early computers and simpler electronic devices often utilized single-core processors due to their lower manufacturing costs and reduced power consumption compared to multi-core designs. While advancements in technology have largely led to the widespread adoption of multi-core processors in modern computers, smartphones, and servers, single-core processors are still found in embedded systems, specialized hardware, and some low-power devices where performance demands are minimal. The limitations of a single-core processor become apparent when running demanding software or multitasking, as performance can significantly degrade.
