  2. Offset (computer science) - Wikipedia

    en.wikipedia.org/wiki/Offset_(computer_science)

    In computer engineering and low-level programming (such as assembly language), an offset usually denotes the number of address locations added to a base address in order to get to a specific absolute address. In this (original) meaning of offset, only the basic address unit, usually the 8-bit byte, is used to

  3. Database storage structures - Wikipedia

    en.wikipedia.org/wiki/Database_storage_structures

    Hash functions calculate the address of the page in which the record is to be stored based on one or more fields in the record hashing functions chosen to ensure that addresses are spread evenly across the address space ‘occupancy’ is generally 40% to 60% of the total file size

  4. Array (data structure) - Wikipedia

    en.wikipedia.org/wiki/Array_(data_structure)

    For a vector with linear addressing, the element with index i is located at the address B + c · i, where B is a fixed base address and c a fixed constant, sometimes called the address increment or stride. If the valid element indices begin at 0, the constant B is simply the address of the first

  5. List of data structures - Wikipedia

    en.wikipedia.org/wiki/List_of_data_structures

    This order is usually determined by the order in which the elements are added to the structure, but the elements can be rearranged in some contexts, such as sorting a list. For a structure that isn't ordered, on the other hand, no assumptions can be made about the ordering of the elements (although a physical implementation of these data types ...

  6. Memory address - Wikipedia

    en.wikipedia.org/wiki/Memory_address

    In a computer using virtual memory, accessing the location corresponding to a memory address may involve many levels. In computing, a memory address is a reference to a specific memory location in memory used by both software and hardware. [1] These addresses are fixed-length sequences of digits, typically displayed and handled as unsigned ...

  7. Data structure alignment - Wikipedia

    en.wikipedia.org/wiki/Data_structure_alignment

    A memory address a is said to be n-byte aligned when a is a multiple of n (where n is a power of 2). 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.

  8. Base address - Wikipedia

    en.wikipedia.org/wiki/Base_address

    In computing, a base address is an address serving as a reference point ("base") for other addresses. Related addresses can be accessed using an addressing scheme . Under the relative addressing scheme, to obtain an absolute address , the relevant base address is taken and an offset (aka displacement) is added to it.
