A user is a person who utilizes a computer or network service. A user often has a user account and is identified to the system by a username (or user name ). [ a] Some software products provide services to other systems and have no direct end users .
In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [ 1] It can sometimes be a high-level description that ignores details of the implementation. [ 2] At a more detailed level, the description may include the instruction set architecture design ...
Flynn's taxonomy. Flynn's taxonomy is a classification of computer architectures, proposed by Michael J. Flynn in 1966 [ 1] and extended in 1972. [ 2] The classification system has stuck, and it has been used as a tool in the design of modern processors and their functionalities. Since the rise of multiprocessing central processing units (CPUs ...
Windows domain. A Windows domain is a form of a computer network in which all user accounts, computers, printers and other security principals, are registered with a central database located on one or more clusters of central computers known as domain controllers. Authentication takes place on domain controllers.
User environment management is a software solution which enables corporate policy and user preference data, the ‘user personality’, to be abstracted from the delivered operating system and applications and centrally managed. This personality can then be associated with the variety of delivery mechanisms an organization uses ‘on-demand ...
A PDF file is often a combination of vector graphics, text, and bitmap graphics. The basic types of content in a PDF are: Typeset text stored as content streams (i.e., not encoded in plain text ); Vector graphics for illustrations and designs that consist of shapes and lines;
User Account Control ( UAC) is a mandatory access control enforcement feature introduced with Microsoft 's Windows Vista [ 1] and Windows Server 2008 operating systems, with a more relaxed [ 2] version also present in Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, Windows 8.1, Windows Server 2012 R2, Windows 10, and Windows 11.
Machine code. 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.
