In BSD, these parameters are generally objects in a management information base (MIB) that describe tunable limits such as the size of a shared memory segment, the number of threads the operating system will use as an NFS client, or the maximum number of processes on the system; or describe, enable or disable behaviors such as IP forwarding, security restrictions on the superuser (the ...
A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...

A logical journal stores only changes to file metadata in the journal, and trades fault tolerance for substantially better write performance. [9] A file system with a logical journal still recovers quickly after a crash, but may allow unjournaled file data and journaled metadata to fall out of sync with each other, causing data corruption.
The USN Journal (Update Sequence Number Journal), or Change Journal, [1] is a feature of the Windows NT file system which maintains a record of changes made to the volume. It is not to be confused with the journal used for the NTFS file system journaling .
If the credential is included in an access control list, the access control system unlocks the controlled access point. The transaction is stored in the system for later retrieval; reports can be generated showing the date/time the card was used to enter the controlled access point. The Wiegand effect was used in early access cards. This method ...
A campus credential, more commonly known as a campus card or a campus ID card is an identification document certifying the status of an educational institution's students, faculty, staff or other constituents as members of the institutional community and eligible for access to services and resources.
