  2. Grid (spatial index) - Wikipedia

    en.wikipedia.org/wiki/Grid_(spatial_index)

    The individual cells of a grid system can also be useful as units of aggregation, for example as a precursor to data analysis, presentation, mapping, etc. For some applications (e.g., statistical analysis), equal-area cells may be preferred, although for others this may not be a prime consideration.

  3. Marker-and-cell method - Wikipedia

    en.wikipedia.org/wiki/Marker-and-Cell_method

    The marker-and-cell method is commonly used in computer graphics to discretize functions for fluid and other simulations. [1] It was developed by Francis Harlow and his collaborators at the Los Alamos National Laboratory .

  4. Discrete global grid - Wikipedia

    en.wikipedia.org/wiki/Discrete_global_grid

    The system must also include encoding methods to: address each cell; assign quantized data to cells; and perform algebraic operations on the cells and the data assigned to them. Main concepts of the DGGS Core Conceptual Data Model: reference frame elements, and, functional algorithm elements; comprising: quantization operations,

  5. Spreadsheet - Wikipedia

    en.wikipedia.org/wiki/Spreadsheet

    A cell on a different sheet of the same spreadsheet is usually addressed as: =SHEET2!A1 (that is; the first cell in sheet 2 of the same spreadsheet). Some spreadsheet implementations in Excel allow cell references to another spreadsheet (not the currently open and active file) on the same computer or a local network.

  6. MAC address - Wikipedia

    en.wikipedia.org/wiki/MAC_address

    The Individual Address Block (IAB) is an inactive registry which has been replaced by the MA-S (MAC address block, small), previously named OUI-36, and has no overlaps in addresses with the IAB [6] registry product as of January 1, 2014. The IAB uses an OUI from the MA-L (MAC address block, large) registry, previously called the OUI registry.

  7. Grid (graphic design) - Wikipedia

    en.wikipedia.org/wiki/Grid_(graphic_design)

    A grid applied within an image (instead of a page) using additional angular lines to guide proportions. In graphic design , a grid is a structure (usually two-dimensional ) made up of a series of intersecting straight (vertical, horizontal, and angular) or curved lines ( grid lines ) used to structure content.

  8. MAC address anonymization - Wikipedia

    en.wikipedia.org/wiki/MAC_Address_Anonymization

    Another approach that has been tested is truncating the MAC Address by removing the Organizationally unique identifier (the first 24 bits of the 48 bit MAC Address). [7] However, as only 0.1% of the total Organizationally unique identifier space has been allocated and not all manufacturers fully utilise their allocated MAC Address space, this ...

  9. MAC spoofing - Wikipedia

    en.wikipedia.org/wiki/MAC_spoofing

    The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed. However, many drivers allow the MAC address to be changed. Additionally, there are tools which can make an operating system believe that the NIC has the MAC address of a user's choosing. The process of masking a MAC address is known as MAC spoofing.
