  2. tar (computing) - Wikipedia

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

    In computing, tar is a computer software utility for collecting many files into one archive file, often referred to as a tarball, for distribution or backup purposes. The name is derived from "tape archive", as it was originally developed to write data to sequential I/O devices with no file system of their own, such as devices that use magnetic tape.

  3. Airport surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Airport_surveillance_radar

    The ASR-9 was the first airport surveillance radar to detect weather and aircraft with the same beam and be able to display them on the same screen. It has a digital Moving Target Detection (MTD) processor which uses doppler radar and a clutter map giving advanced ability to eliminate ground and weather clutter and track targets.

  4. pax (command) - Wikipedia

    en.wikipedia.org/wiki/Pax_(command)

    pax is an archiving utility available for various operating systems and defined since 1995. [1] Rather than sort out the incompatible options that have crept up between tar and cpio, along with their implementations across various versions of Unix, the IEEE designed a new archive utility pax that could support various archive formats with useful options from both archivers.

  5. Directory traversal attack - Wikipedia

    en.wikipedia.org/wiki/Directory_traversal_attack

    When a URI request for a file/directory is to be made, build a full path to the file/directory if it exists, and normalize all characters (e.g., %20 converted to spaces). It is assumed that a 'Document Root' fully qualified, normalized, path is known, and this string has a length N. Assume that no files outside this directory can be served.

    RFC 791 describes the procedure for IP fragmentation, and transmission and reassembly of IP packets. [1] RFC 815 describes a simplified reassembly algorithm. [2] The Identification field along with the foreign and local internet address and the protocol ID, and Fragment offset field along with Don't Fragment and More Fragments flags in the IP header are used for fragmentation and reassembly of ...

Per-file compression with gzip, bzip2, lzo, xz or lzma (as opposed to compressing the whole archive). An individual can choose not to ...

  9. Causal graph - Wikipedia

    en.wikipedia.org/wiki/Causal_graph

    In statistics, econometrics, epidemiology, genetics and related disciplines, causal graphs (also known as path diagrams, causal Bayesian networks or DAGs) are probabilistic graphical models used to encode assumptions about the data-generating process. Causal graphs can be used for communication and for inference.
