  2. 64-bit computing - Wikipedia

    en.wikipedia.org/wiki/64-bit_computing

    However, most 32-bit applications will work well. 64-bit users are forced to install a virtual machine of a 16- or 32-bit operating system to run 16-bit applications or use one of the alternatives for NTVDM. [39] Mac OS X 10.4 "Tiger" and Mac OS X 10.5 "Leopard" had only a 32-bit kernel, but they can run 64-bit user-mode code on 64-bit processors.

    AMD64 (also variously referred to by AMD in their literature and documentation as “AMD 64-bit Technology” and “AMD x86-64 Architecture”) was created as an alternative to the radically different IA-64 architecture designed by Intel and Hewlett-Packard, which was backward-incompatible with IA-32, the 32-bit version of the x86 architecture.

    A new exception system: Fewer banked registers and modes. Memory translation from 48-bit virtual addresses based on the existing Large Physical Address Extension (LPAE), which was designed to be easily extended to 64-bit.

  7. dBase - Wikipedia

    en.wikipedia.org/wiki/DBase

    dBase's database system was one of the first to provide a header section for describing the structure of the data in the file. [ citation needed ] This meant that the program no longer required advance knowledge of the data structure, but rather could ask the data file how it was structured.

  8. Operating system - Wikipedia

    en.wikipedia.org/wiki/Operating_system

    The operating system provides an interface between an application program and the computer hardware, so that an application program can interact with the hardware only by obeying rules and procedures programmed into the operating system. The operating system is also a set of services which simplify development and execution of application programs.
