Output device
[3] Display technologies can be classified based on working principle, lighting (or lack thereof), pixel layout, and more.A monochrome display is a type of CRT common in the early days of computing, from the 1960s through the 1980s, before color monitors became popular.[5] A speaker is an output device that produces sound through an oscillating transducer called a driver.Certain models of computers includes a built-in speaker, which may sacrifice audio quality in favor of size.In the latter case, output is often transmitted using SPDIF as either an electrical signal or an optical interface known as TOSLINK.In the case of wireless audio, the computer merely transmits a radio signal, and responsibility of decoding and output is shifted to the speaker.PC speakers are used during Power-on self-test to identify errors during the computer's boot process, without needing a video output device to be present and functional.Unlike a speaker, headphones are not meant to be audible to people nearby, which suits them for use in the public, office or other quiet environments.[15] A printer is a device that outputs data to be put on a physical item, usually a piece of paper.Modern printers can receive data in multiple forms like vector graphics, as an image, a program written in a page description language, or a string of characters.As the operator would enter commands into its keyboard, the teleprinter would output the results onto a piece of paper.A computer can still function without an output device, as is commonly done with servers, where the primary interaction is typically over a data network.A number of protocols exist over serial ports or LAN cables to determine operational status, and to gain control over low-level configuration from a remote location without having a local display device.
