  2. Virtual method table - Wikipedia

    en.wikipedia.org/wiki/Virtual_method_table

    While d and b1 will point to the same memory location after execution of this code, b2 will point to the location d+8 (eight bytes beyond the memory location of d). Thus, b2 points to the region within d that "looks like" an instance of B2, i.e., has the same memory layout as an instance of B2. [clarification needed]

  3. Memory map - Wikipedia

    en.wikipedia.org/wiki/Memory_map

    It is the fastest and most flexible cache organization that uses an associative memory. The associative memory stores both the address and content of the memory word. [further explanation needed] In the boot process of some computers, a memory map may be passed on from the firmware to instruct an operating system kernel about memory layout. It ...

  4. Go (programming language) - Wikipedia

    en.wikipedia.org/wiki/Go_(programming_language)

    Go has a memory model describing how goroutines must use channels or other operations to safely share data. [ 98 ] The existence of channels does not by itself set Go apart from actor model -style concurrent languages like Erlang, where messages are addressed directly to actors (corresponding to goroutines).

  5. Locality of reference - Wikipedia

    en.wikipedia.org/wiki/Locality_of_reference

    Data locality is a typical memory reference feature of regular programs (though many irregular memory access patterns exist). It makes the hierarchical memory layout profitable. In computers, memory is divided into a hierarchy in order to speed up data accesses. The lower levels of the memory hierarchy tend to be slower, but larger.

  6. Buffer overflow - Wikipedia

    en.wikipedia.org/wiki/Buffer_overflow

    If this overwrites adjacent data or executable code, this may result in erratic program behavior, including memory access errors, incorrect results, and crashes. Exploiting the behavior of a buffer overflow is a well-known security exploit. On many systems, the memory layout of a program, or the system as a whole, is well defined.

  8. Pointer (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Pointer_(computer_programming)

    A pointer a pointing to the memory address associated with a variable b, i.e., a contains the memory address 1008 of the variable b.In this diagram, the computing architecture uses the same address space and data primitive for both pointers and non-pointers; this need should not be the case.

  9. Page table - Wikipedia

    en.wikipedia.org/wiki/Page_table

    A similar mechanism is used for memory-mapped files, which are mapped to virtual memory and loaded to physical memory on demand. When physical memory is not full this is a simple operation; the page is written back into physical memory, the page table and TLB are updated, and the instruction is restarted.
