The name originates from the Basic Input/Output System used in the CP/M operating system in 1975. [2] [3] The BIOS firmware was originally proprietary to the IBM PC; it was reverse engineered by some companies (such as Phoenix Technologies) looking to create compatible systems. The interface of that original system serves as a de facto standard.
In computing, input/output (I/O, i/o, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, such as another computer system, peripherals, or a human operator. Inputs are the signals or data received by the system and outputs are the signals or data sent from it.
It is theorized that the brain works in a set sequence, as does a computer. The sequence goes as follows, "receives input, processes the information, and delivers an output". This theory suggests that we as humans will process information in a similar way. Like a computer receives input the mind will receive information through the senses. If ...
The input–process–output model. The input–process–output (IPO) model, or input-process-output pattern, is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. Many introductory programming and systems analysis texts introduce this as the ...
The assumption is that adding a transducer layer, that is, an input-output system, to an object should not change whether that object has mental states. The transducer layer is restricted to producing behavior according to a simple mapping, such as a lookup table, from inputs to actions on the system, and from the state of the system to outputs.
The input–process–output (IPO) model of teams provides a framework for conceptualizing teams. The IPO model suggests that many factors influence a team's productivity and cohesiveness . It "provides a way to understand how teams perform, and how to maximize their performance".
These units may include abstract elements such as features, shapes and words, and are generally categorised into three types: input, output and hidden units. Input units receive signals from either sensory stimuli or other parts of the processing system. The output units send signals out of the system. The hidden units function entirely inside ...
In computing, an input device is a piece of 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 , computer mice , scanners , cameras, joysticks , and microphones .
