(1) A portion of a page set. Each partition corresponds to a single, independently extendable data set. Partitions can be extended to a maximum size of 1, 2, or 4 gigabytes, depending on the number of partitions in the partitioned page set. All partitions of a given page set have the same maximum size.
(2) On a personal computer hard disk, one of four possible storage areas of variable size; one may be accessed by DOS and each of the others may be assigned to another operating system.
(3) A subset of the active cluster nodes that result from a network failure. Members of a partition maintain connectivity with each other.
(4) A logical division of storage on a fixed disk.
(5) In VSE, a division of the virtual address area that is available for program execution.
(6) In BMS, an addressable subset of a display device's internal resources, consisting of a fixed part of the device's screen, and a fixed part of its internal storage. See also presentation space, viewport.
(7) In basic N_UP printing, the division of the medium presentation space into a specified number of equal-sized areas in a manner determined by the current physical medium.
(8) In activity diagrams, a rectangular, uniquely named grouping that shows activity nodes and edges that have common characteristics. Partitions provide a view of the behaviors in an activity diagram, but do not affect the control flow or object flow.
(9) In architecture, a subset of classifiers or packages at the same level of abstraction. A partition represents a vertical slice through an architecture, whereas a layer represents a horizontal slice.
