The application software layer interfaces with the operating system, which in turn communicates with the hardware. The arrows indicate information flow. Software is a collection of programs and data that tell a computer how to perform specific tasks. Software often includes associated software documentation. [1]
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 ). [4] [5] [6] Though more often considered an academic ...
AIDA64 is a system information, diagnostics, and auditing application developed by FinalWire Ltd (a Hungarian company) that runs on Windows, Android, iOS, Windows Phone, Tizen, ChromeOS and Sailfish OS operating systems. It displays detailed information on the components of a computer. Information can be saved to file in formats such as HTML ...
Information science. Information technology ( IT) is a set of related fields that encompass computer systems, software, programming languages and data and information processing and storage. [1] IT forms part of information and communications technology (ICT). [2] An information technology system ( IT system) is generally an information system ...
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations ( computation ). Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. The term computer system may refer to a nominally ...
An artist's depiction of a 2000s-era desktop-style personal computer, which includes a metal case with the computing components, a display monitor and a keyboard (mouse not shown) A personal computer, often referred to as a PC, is a computer designed for individual use. [1] It is typically used for tasks such as word processing, internet ...
Quantum computing. Quantum System One, a quantum computer by IBM from 2019 with 20 superconducting qubits [1] A quantum computer is a computer that takes advantage of quantum mechanical phenomena. On small scales, physical matter exhibits properties of both particles and waves, and quantum computing leverages this behavior, specifically quantum ...
A real-time operating system (RTOS) is an operating system intended for applications with fixed deadlines ( real-time computing ). Such applications include some small embedded systems, automobile engine controllers, industrial robots, spacecraft, industrial control, and some large-scale computing systems.
