Examples include Ethernet-connected workstation networks and rack-mounted workstations dedicated to parallel computing. See workstation farm and distributed computer.
A group of computers that work together to provide services. Example: Homer is a cluster of computers that provide email, file and print services.
A group of disk sectors. The operating system assigns a unique number to each cluster and then keeps track of files according to which clusters they use. Occasionally, the operating system marks a cluster as being used even though it is not assigned to any file. This is called a lost cluster. You can free up disk space by reassigning lost clusters, but you should first make sure that the clusters do not, in fact, contain valuable data. In DOS and Windows, you can find lost clusters with the Scandisk utility. DOS and Windows keep track of clusters with the File Allocation Table (FAT). The size of each cluster depends on the disk's partition size.
Group of compounds which are related by structural or behavioral properties. Organizing a set of compounds into clusters is often used in assessing the diversity of those compounds, or in developing SAR (structure-activity relationship) models.

The allocation unit used by the filesystem (the "quantum" of data read from or written to the filesystem, similar to sector on the disk). Each file on the filesystem occupies zero or an integral number of clusters (with a few exceptions). Cluster size is an integer multiple of the sector size. Disk ( or Drive, Physical Disk, Physical Drive) - physical device used to store data, typical example being an "IBM/Hitachi Deskstar hard drive". Other media types like Iomega ZIP disks, flash memory cards, flash USB drives and so on are also referred to as "disks" for the sake of simplicity. The same term can sometimes be applied to RAID arrays as a whole (like this: Array #1 on a Promise controller) and to the individual drives in RAID array.

The grouping of similar objects in a multidimensional space. Clustering is used for constructing new features which are abstractions of the existing features of those objects. The quality of the clustering depends crucially on the distance metric in the space. In bioinformatics, clustering is performed on sequences, high-throughput expression and other experimental data. Clusters of partial or complete gene sequences can be used to identify the complete (contiguous) sequence and to better identify its function. Clustering expression data enables the researcher to discern patterns of co-regulation in groups of genes.

If your file is large then it will be written to a group of clusters that are linked together to form a cluster chain.

In these languages, code points can be turned into appropriate glyphs only by looking at other code points around them: the ''cluster'' of which they are part. In some languages, such as Devanagari, the order of glyphs within a cluster can differ from the order of the corresponding Unicode code points. See Windows Glyph Processing on the Microsoft typography site for further details.

A cluster is defined as an allocation unit. At least one cluster is allocated to each file, regardless of the file's size, that is stored in the DOS environment. The cluster size increases with the partition size determined during formatting. With a 1024 MB partition, the cluster size is 32 KB.

Network Load Balancing provides a software solution for clustering multiple computers running Windows 2000 Server that provides networked services over the Internet and private intranets. In file systems a cluster is the smallest amount of disk space that can be allocated to hold a file. All file systems used by Windows 2000 organize hard disks based on clusters, also called allocation units. The smaller the cluster size, the more efficiently a disk stores information. If no cluster size is specified during formatting, Windows 2000 picks defaults based on the size of the volume and the file system used. These defaults are selected to reduce the amount of space lost and the amount of fragmentation on the volume.

When a file with size larger than one cluster is stored, it uses the memory areas of the hard disk in units of clusters.
A cluster is a group of synergistic and technically related projects. Project clusters are a defined group of RTD projects benefiting from synergies - to maximise European added value within a given field and establish a critical mass of resources at the European level.(DE:Bündel, FR:Grappe de projets, IT:Cluster)
cluster is the set of systems (nodes) configured to work together as a single computing resource. A cluster is identified by a simple name and a cluster ID. A cluster running multiple operating systems is known as a multiOS cluster . There is only one cluster that may be formed from a given pool of nodes. Disks or logical units (LUNs) are assigned to clusters by recording the name of the cluster on the disk (or LUN). Thus, if any disk is accessible (via a Fibre Channel connection) from machines in multiple clusters, then those clusters must have unique names. When members of a cluster send messages to each other, they identify their cluster via the cluster ID. Cluster names must be unique. Because of the above restrictions on cluster names and cluster IDs, and because cluster names and cluster IDs cannot be changed once the cluster is created (without deleting the cluster and recreating it), SGI advises that you choose unique names and cluster IDs for each of the clusters within your organization.

A cluster is the smallest linguistic unit that can be shaped. In languages such as Arabic and many of the Indic languages, the glyphs used to represent each character (Unicode code point) depend strongly on the surrounding code points, which constitute the cluster. In these languages, applications can translate code points into appropriate glyphs only by looking at the cluster. In some scripts, such as Devanagari, the order of glyphs within a cluster can differ from the order of the corresponding Unicode code points. For more information, see Windows Glyph Processing on the Microsoft typography site.

Clustering is both visual and spatial with the dwellings scaled and sited to maintain coherent relationships to each other and the surrounding landscape.

In data storage, the smallest amount of disk space that can be allocated to hold a file. All file systems used by Windows organize hard disks based on clusters, which consist of one or more contiguous sectors. The smaller the cluster size, the more efficiently a disk stores information.

In certain filesystem types like the File Allocation Table (FAT) filesystem of MS-DOS or the NTFS filesystem of Windows NT, a cluster is the unit of disk space allocation for files and directories. In order to reduce the overhead of managing on-disk data structures, the filesystem does not allocate individual disk sectors, but contiguous groups of sectors, called clusters.
