Terms in this set (25)
device that accepts information (in the form of digitalized data) and manipulates it for some result
In computing, data is information that has been translated into a form that is more convenient to move or process
Information is stimuli that has meaning in some context for its receive
storage, storage devices
An object-based storage device or object storage device (OBSD or OSD) is a computer storage system that organizes data
Information processing is the change (processing) of information in any manner detectable by an observe
input, input devices
In computing, an input device is a peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or information appliance. Examples of input devices include keyboards, mouse, scanners, digital cameras and joysticks.
output, output devices
An output device is any device used to send data from a computer to another device or user. Most computer data output that is meant for humans is in the form of audio or video. Thus, most output devices used by humans are in these categories. Examples include monitors, projectors, speakers, headphones and printers.
Cloud storage is a cloud computing model in which data is stored on remote servers accessed from the Internet, or "cloud." It is maintained, operated and managed by a cloud storage service provider on a storage servers that are built on virtualization techniques.
Central processing unit
the part of a computer in which operations are controlled and executed.
operate on (computer data) by means of a program.
an integrated circuit that contains all the functions of a central processing unit of a computer.
Computer memory is any physical device capable of storing information temporarily or permanently. For example, Random Access Memory (RAM), is a volatile memory that stores information on an integrated circuit used by the operating system, software, and hardware
Random access memory
RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers.
auxiliary memory from which high-speed retrieval is possible.
The main circuit board inside a computer that everything in the computer plugs into and contains the central processing unit, the bus, memory sockets, expansion slots, and other components
communication device is piece of equipment or hardware designed to move information or data from one place to another, in other words, allowing one computer device to communicate with another.
Application software is a program or group of programs designed for end users. These programs are divided into two classes: system software and application software.
System software is a type of computer program that is designed to run a computer's hardware and application programs. If we think of the computer system as a layered model, the system software is the interface between the hardware and user applications.
desktop computer is a personal computer that fits on or under a desk. They usually consist of a monitor, keyboard, mouse and either a horizontal or vertical (tower) form factor. Unlike a laptop, which is portable, a desktop computer is meant to stay at one location.
computer that is portable and suitable for use while traveling.
Also called tablet computer. a very thin, portable computer, usually battery-powered, having a touchscreen as the primary interface and input device and lacking a physical keyboard and lid.
small laptop computer designed primarily for accessing Internet-based applications.
particularly powerful mainframe computer.
An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. Embedded systems control many devices in common use today.
