Bisection is a method used in software development to identify change sets that result in a specific behavior change. It is mostly employed for finding the patch that introduced a bug . Another application area is finding the patch that indirectly fixed a bug.
Like Nachos, Pintos is intended to introduce undergraduates to concepts in operating system design and implementation by requiring them to implement significant portions of a real operating system, including thread and memory management and file system access. Pintos also teaches students valuable debugging skills.
An operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time , mass storage , peripherals, and ...
The classic Mac OS [a] (System Software) is the series of operating systems developed for the Macintosh family of personal computers by Apple Inc. from 1984 to 2001, starting with System 1 and ending with Mac OS 9. The Macintosh operating system is credited with having popularized the graphical user interface concept. [32]
An object-oriented operating system [1] is an operating system that is designed, structured, and operated using object-oriented programming principles. An object-oriented operating system is in contrast to an object-oriented user interface or programming framework , which can be run on a non-object-oriented operating system like DOS or Unix .
The following table contains relatively general attributes of version-control software systems, including: Repository model, the relationship between copies of the source code repository Client–server , users access a master repository via a client ; typically, their local machines hold only a working copy of a project tree.
An operating system abstraction layer (OSAL) provides an application programming interface (API) to an abstract operating system making it easier and quicker to develop code for multiple software or hardware platforms. It can make an application less dependent on any one specific operating system.
Extensibility is a software engineering and systems design principle that provides for future growth. Extensibility is a measure of the ability to extend a system and the level of effort required to implement the extension.
