Vinnsluminni

Vinnsluminni is an Icelandic term that can refer to two related but distinct concepts. In computing, it denotes the computer’s volatile memory used by the central processing unit to store data and instructions that are actively being used. In cognitive psychology, vinnsluminni denotes the system of temporary storage and manipulation that enables reasoning, learning, and comprehension.

In computing, vinnsluminni is typically implemented as RAM (random access memory). It is fast but loses its contents when power is removed. Main memory usually consists of DRAM modules, while smaller, faster caches (such as L1 and L2, sometimes L3) use SRAM. The size and speed of vinnsluminni affect multitasking performance, data throughput, and the ability to work with large datasets. It is distinct from non-volatile storage such as SSDs or hard drives, which retain data without power. Memory bandwidth and latency influence system responsiveness, and upgrading memory can reduce paging and improve overall performance.

In psychology, vinnsluminni refers to the temporary storage and manipulation of information needed for complex cognitive tasks. The concept is linked to models of working memory, which include components responsible for holding verbal and visual information and a central control system that regulates attention and processing. Capacity is limited, often described as a few items or chunks, and information can decay within seconds without rehearsal.

Usage of the term depends on context: in Icelandic technical discussions it commonly means RAM, while in psychological contexts it means working memory.
