are the stages of compilation that need to be satisfied before going on to other compilation stages in order to successfully compile a program. This term is also used where one set of programs that you wish to install are dependant on other programs that may or may not be on your system, in which case you may get a message telling you that the system needs to "satisfy dependencies" in order to continue the installation.

An attribute of a package that indicates whether the package requires another package to work properly. Dependencies may be either 'prerequisite' (if the package must be installed before the current package is installed) or 'corequisite' (if the package must be installed before the current package is executed).

When referring to packages, dependencies are requirements that exist between packages. For example, package foo may require files that are installed by package bar. In this example, bar must be installed, or else foo will have unresolved dependencies. RPM will not normally allow packages with unresolved dependencies to be installed.

The logical relationships between tasks. Often used for projects in a Program.

Related events or plans that could significantly affect the outcome of a project.

Links between project tasks.  There are 3 types of dependencies: Causal, where 1 task must be completed before another can begin (have to bake bread before you can make a sandwich) critical path schedules are based only on causal dependencies Resource, where a task is limited by availability of resources (more bread can be baked by 2 bakers, but only 1 is available) Discretionary, optional task sequence preferences that, though not required, may reflect organizational preferences

Components can have dependencies on other components. There are several notions to keep in mind when considering component dependencies: The syntax we use to denote component dependencies must be of the form ${variable} so that dependency substitution can be performed and dependency resolution can take place. Component dependencies must be resolved before components can be executed. When designing component dependencies, keep watchful of inadvertently creating circular dependencies.

plural of dependency.

A relation between activities, such that one requires input from the other.
