WordDefinition
memory segmentationan operating system memory management technique of dividing a computer's primary memory into segments or sections.
memory addressIn computing, a memory address is a reference to a specific memory location in memory used by both software and hardware.
input/output base address
global descriptor tablea data structure used by Intel x86-family processors starting with the 80286 in order to define the characteristics of the various memory areas used during program execution, including the base address, the size, and access privileges like executability and writability.
code segmentIn computing, a code segment, also known as a text segment or simply as text, is a portion of an object file or the corresponding section of the program's virtual address space that contains executable instructions.
address generation unitThe address generation unit, sometimes also called address computation unit, is an execution unit inside central processing units (CPUs) that calculates addresses used by the CPU to access main memory.
memory buffer registerA memory buffer register or memory data register is the register in a computer's CPU that stores the data being transferred to and from the immediate access storage.
memory mapIn computer science, a memory map is a structure of data (which usually resides in memory itself) that indicates how memory is laid out.
memory address registerIn a computer, the memory address register is the CPU register that either stores the memory address from which data will be fetched to the CPU registers, or the address to which data will be sent and stored via system bus.
physical addressIn computing, a physical address (also real address, or binary address), is a memory address that is represented in the form of a binary number on the address bus circuitry in order to enable the data bus to access a particular storage cell of main memory, or a register of memory-mapped I/O device.
interrupt descriptor tableThe interrupt descriptor table is a data structure used by the x86 architecture to implement an interrupt vector table.
logical addressnoun(computing, software) The address at which an item appears to reside from the perspective of an executing application program.
memory-mapped fileA memory-mapped file is a segment of virtual memory that has been assigned a direct byte-for-byte correlation with some portion of a file or file-like resource.
address spacenoun(computing) A range of discrete addresses, all the address locations available in a particular, named, subset of a computer's (virtual or real) memory.
page tablenoun(computing) A data structure used by a virtual memory implementation to store the mappings between physical and virtual addresses.
sequential access memoryIn computing, sequential access memory is a class of data storage devices that read stored data in a sequence.
semiconductor memorynounAny device used to store and retrieve digital information that is manufactured using integrated circuit technology.
flat memory modelFlat memory model or linear memory model refers to a memory addressing paradigm in which "memory appears to the program as a single contiguous address space."
distributed shared memoryIn computer science, distributed shared memory is a form of memory architecture where physically separated memories can be addressed as a single shared address space.
64-bit computingIn computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits wide.
