The term application software refers to all applications collectively [3] and can be used to differentiate from system and utility software. Applications may be bundled with the computer and its system software or published separately. Applications may be proprietary or open-source. [4] The short term app (coined in 1981 or earlier [5]) became ...
Computer science is the study of computation, information, and automation. [1] [2] [3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software).
A kernel is the core part of the operating system that defines an application programming interface for applications programs (including some system software) and an interface to device drivers. Device drivers and firmware , including computer BIOS or UEFI , provide basic functionality to operate and control the hardware connected to or built ...
Application software is the key to unlocking the potential of the computer system. [123] Enterprise application software bundles accounting, personnel, customer, and vendor applications. Examples include enterprise resource planning , customer relationship management , and supply chain management software .
A software system is a system of intercommunicating components based on software forming part of a computer system (a combination of hardware and software). It "consists of a number of separate programs, configuration files, which are used to set up these programs, system documentation, which describes the structure of the system, and user documentation, which explains how to use the 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.

Computer science or computing science (abbreviated CS or Comp Sci) is the scientific and practical approach to computation and its applications. A computer scientist specializes in the theory of computation and the design of computational systems. [43] Its subfields can be divided into practical techniques for its implementation and application ...
