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.
By simplifying their system compared to Multics, ITS's authors were able to quickly [clarification needed] produce a functional operating system for their lab. [4] ITS was written in assembly language , originally for the Digital Equipment Corporation PDP-6 computer, but the majority of ITS development and use was on the later, largely ...
The following outline is provided as an overview of and topical guide to information technology: . Information technology (IT) – microelectronics based combination of computing and telecommunications technology to treat information, including in the acquisition, processing, storage and dissemination of vocal, pictorial, textual and numerical information.
The other extreme is that the content of each sentence in a documents is converted in the formal knowledge representation language and thus the objects that are mentioned in those sentences become an integral part of the computer interpretable knowledge model. For example, the knowledge that the API 617 standard contains a standard ...

Using x86 as an example, there is a special [clarification needed] gate structure which is referenced by the call instruction that transfers control in a secure way [clarification needed] towards predefined entry points in lower-level (more trusted) rings; this functions as a supervisor call in many operating systems that use the ring ...
The internet often has to deal with complex, unstructured data that cannot be relied on to fit a specific data model. The technology of knowledge-based systems, and especially the ability to classify objects on demand, is ideal for such systems. The model for these kinds of knowledge-based internet systems is known as the Semantic Web. [13]
Informatics (a combination of the words "information" and "automatic") is the study of computational systems. [1] [2] According to the ACM Europe Council and Informatics Europe, informatics is synonymous with computer science and computing as a profession, [3] in which the central notion is transformation of information.
