  2. tar (computing) - Wikipedia

    en.wikipedia.org/wiki/Tar_(computing)

    Most tar implementations can also read and create cpio and pax (the latter actually is a tar-format with POSIX-2001-extensions). Key implementations in order of origin: Solaris tar, based on the original Unix V7 tar and comes as the default on the Solaris operating system; GNU tar is the default on most Linux distributions. It is based on the ...

  3. Decision-to-decision path - Wikipedia

    en.wikipedia.org/wiki/Decision-to-decision_path

    A decision-to-decision path, or DD-path, is a path of execution (usually through a flow graph representing a program, such as a flow chart) between two decisions. More recent versions of the concept also include the decisions themselves in their own DD-paths. A flow graph of a program. Each color denotes a different DD-path.

  4. Physical design (electronics) - Wikipedia

    en.wikipedia.org/wiki/Physical_design_(electronics)

    In integrated circuit design, physical design is a step in the standard design cycle which follows after the circuit design.At this step, circuit representations of the components (devices and interconnects) of the design are converted into geometric representations of shapes which, when manufactured in the corresponding layers of materials, will ensure the required functioning of the components.

  5. Path analysis (statistics) - Wikipedia

    en.wikipedia.org/wiki/Path_analysis_(statistics)

    In statistics, path analysis is used to describe the directed dependencies among a set of variables. This includes models equivalent to any form of multiple regression analysis, factor analysis, canonical correlation analysis, discriminant analysis, as well as more general families of models in the multivariate analysis of variance and covariance analyses (MANOVA, ANOVA, ANCOVA).

  6. Functional flow block diagram - Wikipedia

    en.wikipedia.org/wiki/Functional_flow_block_diagram

    Figure 1: Functional flow block diagram format. [1] A functional flow block diagram (FFBD) is a multi-tier, time-sequenced, step-by-step flow diagram of a system's functional flow. [2] The term "functional" in this context is different from its use in functional programming or in mathematics, where pairing "functional" with "flow" would be ...

  7. Signal-flow graph - Wikipedia

    en.wikipedia.org/wiki/Signal-flow_graph

    A signal-flow graph or signal-flowgraph (SFG), invented by Claude Shannon, [1] but often called a Mason graph after Samuel Jefferson Mason who coined the term, [2] is a specialized flow graph, a directed graph in which nodes represent system variables, and branches (edges, arcs, or arrows) represent functional connections between pairs of nodes.

  8. ar (Unix) - Wikipedia

    en.wikipedia.org/wiki/Ar_(Unix)

    The archiver, also known simply as ar, is a Unix utility that maintains groups of files as a single archive file.Today, ar is generally used only to create and update static library files that the link editor or linker uses and for generating .deb packages for the Debian family; it can be used to create archives for any purpose, but has been largely replaced by tar for purposes other than ...

  9. Digital timing diagram - Wikipedia

    en.wikipedia.org/wiki/Digital_timing_diagram

    The timing diagram example on the right describes the Serial Peripheral Interface (SPI) Bus. Most SPI master nodes can set the clock polarity (CPOL) and clock phase (CPHA) with respect to the data. This timing diagram shows the clock for both values of CPOL and the values for the two data lines (MISO & MOSI) for each value of CPHA.
