  2. Queued Sequential Access Method - Wikipedia

    en.wikipedia.org/wiki/Queued_sequential_access...

    QSAM manages truncated final blocks and truncated embedded blocks completely transparently to the user. The QSAM application program interface can be compared with the interface offered by open , read , write and close calls (using file handles) in other operating systems such as Unix and Windows .

  3. Decomposition of a module - Wikipedia

    en.wikipedia.org/wiki/Decomposition_of_a_module

    Since a simple module is indecomposable, a semisimple decomposition is an indecomposable decomposition (but not conversely). If the endomorphism ring of a module is local, then, in particular, it cannot have a nontrivial idempotent: the module is indecomposable. Thus, a decomposition with local endomorphism rings is an indecomposable decomposition.

  4. Pluggable Authentication Module - Wikipedia

    en.wikipedia.org/.../Pluggable_authentication_module

    A pluggable authentication module (PAM) is a mechanism to integrate multiple low-level authentication schemes into a high-level application programming interface (API). PAM allows programs that rely on authentication to be written independently of the underlying authentication scheme.

  5. Linux PAM - Wikipedia

    en.wikipedia.org/wiki/Linux_PAM

    Linux Pluggable Authentication Modules (PAM) is a suite of libraries that allow a Linux system administrator to configure methods to authenticate users. It provides a flexible and centralized way to switch authentication methods for secured applications by using configuration files instead of changing application code. [ 1 ]

  6. Program database - Wikipedia

    en.wikipedia.org/wiki/Program_database

    Program database (PDB) is a file format (developed by Microsoft) for storing debugging information about a program (or, commonly, program modules such as a DLL or EXE).PDB files commonly have a .pdb extension.

  7. Environment variable - Wikipedia

    en.wikipedia.org/wiki/Environment_variable

    A running program can access the values of environment variables for configuration purposes. Shell scripts and batch files use environment variables to communicate data and preferences to child processes. They can also be used to store temporary values for reference later in a shell script.

  8. Secure access module - Wikipedia

    en.wikipedia.org/wiki/Secure_access_module

    A secure access module. A Secure Access Module (SAM), also known as a Secure Application Module, is a piece of cryptographic hardware typically used by smart card card readers to perform mutual key authentication. [1] [2] [3] SAMs can be used to manage access in a variety of contexts, such as public transport fare collection and point of sale ...

    en.wikipedia.org/wiki/Data_truncation

    Depending on what type of data validation a program or operating system has, the data may be truncated silently (i.e., without informing the user), ...
