Brad Cox refined the concept of a software component in the 1980s. [7] He attempted to create an infrastructure and market for reusable third-party components by inventing the Objective-C programming language. [8] IBM introduced System Object Model (SOM) in the early 1990s. [9] Microsoft introduced Component Object Model (COM) in the

In the decade preceding Unix, computers had grown enormously in power – to the point where computer operators were looking for new ways to get people to use their spare time on their machines. One of the major developments during this era was time-sharing , whereby a number of users would get small slices of computer time, at a rate at which ...
This description, often called a hardware design model, allows hardware designers to understand how their components fit into a system architecture and provides to software component designers important information needed for software development and integration. Clear definition of a hardware architecture allows the various traditional ...
In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.
Policy-based component that enables or disables execution of software based on rules such as location, properties and digital signature Windows 7 Professional, Enterprise and Ultimate editions Windows Server 2008 R2: BitLocker Drive Encryption: Disk encryption software, designed to protect data by providing encryption for entire volumes
A technology consisting of computer components and recording media used to retain digital data. It is a core function and fundamental component of computers. [1] device memory local memory associated with a hardware device such as a graphics processing unit or OpenCL compute device, distinct from main memory. Digital Video Disc (DVD)
The universal Turing machine was a type of stored-program computer capable of mimicking the operations of any Turing machine (computer model) based on the software instructions passed to it. The storage of computer programs is key to the operation of modern computers and is the connection between computer hardware and software. [7]
