  2. File URI scheme - Wikipedia

    en.wikipedia.org/wiki/File_URI_scheme

    [4] The single slash between host and path denotes the start of the local-path part of the URI and must be present. [5] A valid file URI must therefore begin with either file:/path (no hostname), file:///path (empty hostname), or file://hostname/path. file://path (i.e. two slashes, without a hostname) is never correct, but is often used.

  3. Express Data Path - Wikipedia

    en.wikipedia.org/wiki/Express_Data_Path

    XDP (eXpress Data Path) is an eBPF-based high-performance network data path used to send and receive network packets at high rates by bypassing most of the operating system networking stack. It is merged in the Linux kernel since version 4.8. [2] This implementation is licensed under GPL. Large technology firms including Amazon, Google and ...

  4. PATH (variable) - Wikipedia

    en.wikipedia.org/wiki/PATH_(variable)

    On DOS, OS/2, and Windows operating systems, the %PATH% variable is specified as a list of one or more directory names separated by semicolon (;) characters. [ 5 ] The Windows system directory (typically C:\WINDOWS\system32 ) is typically the first directory in the path, followed by many (but not all) of the directories for installed software ...

  5. Namespace - Wikipedia

    en.wikipedia.org/wiki/Namespace

    [2] [3] [4] Computer networks and distributed systems assign names to resources, such as computers, printers, websites, and remote files. Operating systems can partition kernel resources by isolated namespaces to support virtualization containers. Similarly, hierarchical file systems organize files in directories. Each directory is a separate ...

  6. Suffix tree - Wikipedia

    en.wikipedia.org/wiki/Suffix_tree

    ERA is a recent parallel suffix tree construction method that is significantly faster. ERA can index the entire human genome in 19 minutes on an 8-core desktop computer with 16 GB RAM. On a simple Linux cluster with 16 nodes (4 GB RAM per node), ERA can index the entire human genome in less than 9 minutes. [38]

  7. Tree (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Tree_(abstract_data_type)

    The number of edges along the shortest path between two nodes. Level The level of a node is the number of edges along the unique path between it and the root node. [4] This is the same as depth. Width The number of nodes in a level. Breadth The number of leaves. Forest A set of one or more disjoint trees. Ordered tree

  8. Data structure alignment - Wikipedia

    en.wikipedia.org/wiki/Data_structure_alignment

    In this context, a byte is the smallest unit of memory access, i.e. each memory address specifies a different byte. An n-byte aligned address would have a minimum of log 2 (n) least-significant zeros when expressed in binary. The alternate wording b-bit aligned designates a b/8 byte aligned address (ex. 64-bit aligned is 8 bytes aligned).

  9. Flex (lexical analyser generator) - Wikipedia

    en.wikipedia.org/wiki/Flex_(lexical_analyser...

    [3] [4] It is frequently used as the lex implementation together with Berkeley Yacc parser generator on BSD-derived operating systems (as both lex and yacc are part of POSIX), [5] [6] [7] or together with GNU bison (a version of yacc) in *BSD ports [8] and in Linux distributions.
