End-user computing ( EUC) refers to systems in which non-programmers can create working applications. [1] EUC is a group of approaches to computing that aim to better integrate end users into the computing environment. These approaches attempt to realize the potential for high-end computing to perform problem-solving in a trustworthy manner.
End user. In product development, an end user (sometimes end-user) [a] is a person who ultimately uses or is intended to ultimately use a product. [1] [2] [3] The end user stands in contrast to users who support or maintain the product, [4] such as sysops, system administrators, database administrators, [5] information technology (IT) experts ...
t. e. 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 .
End-User Development can be defined as a set of methods, techniques, and tools that allow users of software systems, who are acting as non-professional software developers, at some point to create, modify or extend a software artifact. Ko et al. propose the following definition: [13]
A computer monitor provides a visual interface between the machine and the user. Human–computer interaction ( HCI) is research in the design and the use of computer technology, which focuses on the interfaces between people ( users) and computers. HCI researchers observe the ways humans interact with computers and design technologies that ...
The term user space (or userland) refers to all code that runs outside the operating system's kernel. User space usually refers to the various programs and libraries that the operating system uses to interact with the kernel: software that performs input/output , manipulates file system objects, application software , etc.
A protection ring is one of two or more hierarchical levels or layers of privilege within the architecture of a computer system. This is generally hardware-enforced by some CPU architectures that provide different CPU modes at the hardware or microcode level. Rings are arranged in a hierarchy from most privileged (most trusted, usually numbered ...
1. Physical layer. v. t. e. The Open Systems Interconnection ( OSI) model is a reference model from the International Organization for Standardization (ISO) that "provides a common basis for the coordination of standards development for the purpose of systems interconnection." [2] In the OSI reference model, the communications between systems ...
