“garbage collection” to “GSS-API”

garbage collection

(n.) The automatic detection and freeing of memory that is no longer in use. The Java^TM runtime system performs garbage collection so that programmers never explicitly free objects.

gateway

(n.) Now called an IP router. “Gateway” and “application gateway” indicate systems that translate from one native format to another; for example, X.400 to or from RFC 822 email gateways.

generic resource

(n.) An application daemon and its child processes that are put under control of the Resource Group Manager as part of a generic resource type.

generic resource type

(n.) A template for a data service. A generic resource type can be used to make a simple application into a failover data service (stop on one node, start on another). This type does not require programming by the Sun^TM Cluster API.

genlock

(n.) The capability of a video device to accept a synchronous signal so that the device input or output pixels are precisely in phase with the input sync.

geographical addressing

(n.) A mechanism by which a part of the physical address is presented to each SBus slave as an individual select signal so that only one slave is selected at any given time.

geometric primitive

(n.) See primitive.

GID

(group identification number) (n.) The number used by the system to control access to accounts owned by other users.

GKS

graphical kernel system.

global

(adj.) Capable of having extended or general scope. For example, a global substitution of one word for another in a file affects all occurrences of the word. Contrast with local.

global device

(n.) A device that is accessible from all cluster members, such as disk, CD-ROM, and tape.

global-device namespace

(n.) A namespace that contains the logical, cluster-wide names for global devices. Local devices in the Solaris^TM Operating System are defined in the /dev/dsk, /dev/rdsk, and /dev/rmt directories. The global-device namespace defines global devices in the /dev/global/dsk, /dev/global/rdsk, and /dev/global/rmt directories.

global interface

(n.) A global network interface that physically hosts shared addresses. See also shared address.

global interface node

(n.) A node that hosts a global interface.

global resource

(n.) A highly available resource that is provided at the kernel level of the Sun^TM Cluster software. Global resources can include disks (HA device groups), the cluster file system, and global networking.

global variable

(n.) A variable used throughout a program. It has a value that can be set by any program statement.

glyph

(n.) A graphical element on the workspace. A glyph can be a button, folder, or other graphical element representing a document or file.

grab

(1) (v.) To move the mouse pointer over an object, and then to press and hold down the mouse button in preparation for moving the object. See also drop.

(2) (n.) In the X protocol, the act of the server obtaining exclusive use for a client of keyboard keys, the keyboard, pointer buttons, and the pointer. A grab is usually for a short time period. See active grab, passive grab.

grab handle

(n.) One of the small squares displayed at the corners and midpoints of a selected graphic object.

graphics accelerator

(n.) A hardware device dedicated to increasing the speed and performance of graphics. Graphics accelerators calculate pixel values, and write them into the frame buffer, freeing the CPU for other operations.

graphics primitive

(n.) See primitive.

gray-scale image

(n.) A type of file that contains more than one bit of information per pixel to convey shades of gray. For example, an image with 256 shades of gray requires 8 bits per pixel.

group

(n.) A collection of users who are referred to by a common name. Determines user access to files. The two types of groups are default user group and standard user group.

group attribute

(n.) An attribute attached to a file or directory that determines user access. See also permissions.

GSS-API

The Generic Security Service Application Programming Interface. A network layer that provides support for various modular security services. GSS-API provides for security authentication, integrity, and confidentiality services. GSS-API also allows maximum portability of applications from a security standpoint. See also authentication, integrity.
