The PAC contains several logical components, including group membership data for authorization, alternate credentials for non-Kerberos authentication protocols, and policy control information for supporting interactive logon.

procedural module: A collection of subroutines and functions.

process matching criteria (PMC): A resource policy object that selects a subset of currently executing processes. Since processes are dynamically created and terminated by the operating system in the course of running workloads, the WSRM Protocol uses PMCs as a means of identifying processes for resource management purposes. PMCs specify partial or full values to be matched against process property fields. Each PMC includes a name and a nonempty set of matching values and can also include a nonempty set of exclusion values. All running processes under management whose path and the associated user name match the values provided in a PMC are selected by that PMC, provided that they are not already selected by another PMC and do not match the exclusion values. Processes selected by a PMC specification at any given time are said to match, or be in, the PMC. A process can be selected by only one PMC at a time. The term resource group" and PMC are used interchangeably.

processor affinity: An element of process matching criteria (PMC), the association between a task or process and a specific processor needed to execute that task. Processor affinity takes advantage of the fact that some remnants of a process might remain in one processor's state (in particular, in its cache) from the last time the process ran, and so scheduling it to run on the same processor the next time could make the process run more efficiently than if it were to run on another processor.

The usage policy identifies all authorized users and the actions that they are authorized to take with the content, in addition to any usage conditions. The publishing license tells a server which usage policies apply to a specific piece of content and grants a server the right to issue Use Licenses (Uls) based on that policy. The publishing license is created when content is protected. Also referred to as "Issuance License (IL)."

The usage policy identifies all authorized users and the actions they are authorized to take with the content, along with any conditions on that usage. The publishing license tells the server what usage policies apply to a given piece of content and grants the server the right to issue use licenses (ULs) based on that policy. The PL is created when content is protected. Also known as an Issuance License (IL).
