klaszter

Klaszter is a term used across multiple disciplines to denote a group of related items that are close to one another, whether in space, properties, or function. The spelling "klaszter" appears as a variant in some language contexts and is often used interchangeably with "cluster" in technical texts. The core idea is a coherent aggregation where members share similarities or proximity that justify treating them as a unit.

In computing, a computer cluster consists of multiple interconnected machines that function as a single system, enabling load balancing, high availability, and parallel processing. In data analysis, cluster analysis is an unsupervised learning technique that partitions data into groups, or clusters, such that items within a cluster are more similar to each other than to items in other clusters; common methods include k-means, hierarchical clustering, and DBSCAN.

In astronomy, star clusters are aggregates of stars bound by gravity, including open clusters and globular clusters. In economics and regional development, industrial or innovation clusters refer to geographic concentrations of interconnected companies and institutions in a particular field, which may foster productivity and knowledge spillovers. In biology and medicine, cell or tissue clusters describe localized groups of cells that share features or functions, as seen in histology slides.
