The boundaries between single-channel video, computer-based art and media installations continue to blur and evolve. A media artwork may have multiple iterations. Artistic practices drive new exhibition modes, from display equipment and formats to issues of audience interaction and access.

What links these practices is the dynamic and often unconventional use and presentation of digital data. The artwork that develops out of these applications of digital technology is also commonly termed "new media" art.

Popular models include the iMac, Mac Pro, and MacBook Pro. <strong>PC</strong> Although the term PC (short for Personal Computer) is broad enough to include Apple computers as well as others, the term is commonly accepted to mean "IBM compatible," which today means Windows machines. PCs have numerous manufacturers, unlike Apple. These manufacturers include Dell, HP, Compaq, Sony. </a></faq_item><faq_item><q>Servers </q><a><strong>Video Server</strong> Just as <b><a href="">DVD</a></b> replaced <b><a href="">VHS</a></b> and <b><a href="">Laserdisc</a></b> for showing video in art spaces, computers are replacing DVD. When a computer is set up with the sole purpose of playing video, this computer is called a Video server, and it can be assembled from a general-purpose computer like a Mac or Windows PC or it can be manufactured as a stand-alone device, like a DVD player. The advantage of a video server is its ability to play many types of video, including HD (high-definition). See Network section for related information.</a></faq_item><faq_item><q>Input Device</q><a>Input devices allow a user to interact with the computer. What kind of input device to use (if not specified by the artist) depends on what level of interaction is necessary to animate the work successfully. Some common input devices are: <strong>Mouse/keyboard</strong> These are the two main input devices for computer installations. The mouse allows for basic <i>point and click</i> interaction and the keyboard allows for more traditional input like text entry. <strong>Touch Screens</strong> Touch screens overlay the display and are typically pressure-sensitive (resistive), electrically-sensitive (capacitive), acoustically-sensitive (SAW or surface acoustic wave) or photo-sensitive (infrared). For simple interactions, these devices replace the keyboard and/or mouse as the primary input device for interacting with a work's content. <strong>Image/Video/Audio</strong> Scanners, digital cameras and camcorders, webcams and microphones all can be used as input devices for computer based installations, not only as an input for image and sound, but as a way to track a user's movement through space. <strong>Gaming Devices</strong> Common video game inputs can also be used in installations, such as joysticks, paddle, and game pads.</a></faq_item><faq_item><q>Output Device</q><a>An output device is any display mechanism that is controlled by a computer, this can include projectors, video displays, and audio monitors. Hard drive playback is an attractive alternative to formats that are unreliable or insist on high compression levels.</a></faq_item><faq_item><q>Connections and Cables</q><a>Connections and cables are devices for moving analog and digital data in and out of the computer. Some are computer specific and others come from traditional AV connection types. <strong>DVI/HDMI</strong> is the standard display output of contemporary computers, which transfers video from the computer to the display digitally. Since most of today's displays (projectors, flat screens) are digital, DVI avoids the digital-to-analog (DA) conversion required if a VGA connection is used (see VGA below). HDMI transfers the video picture the same way as DVI but also includes multiple digital audio channels for surround sound. HDMI is becoming the consumer standard as it is adopted by home theater devices. <strong>VGA</strong> is an analog cable commonly used to connect a computer to a display. VGA accomodates a screen resolution of 640 x 480 pixels. Other resolutions include SVGA = 800 x 600; XGA = 1024 x 768; WXGA = 1280 x 768 (widescreen display); SXGA = 1280 x 1024; UXGA = 1600 x 1200. <strong>DVI to VGA adaptor</strong> Most older projectors only have VGA inputs, while many new computers are only equipped with a DVI output. A DVI to VGA adaptor is a common connector used (especially for Macintosh users) to remedy this incompatibility. <strong>Balanced and Unbalanced Audio</strong> Balanced connections are used in pro environments because the twisted-pair structure of a balanced cable reduces potential noise interference. Unbalanced is by far the more common. These connections can use the same RCA cable and connector used in home video and audio equipment, and also commonly seen connecting to a computer with 1/8" mini connector, like those found on a portable audio player. <strong>USB (Universal Serial Bus)</strong> is a common interface for connecting external devices to computers. USB cables can be daisy-chained together from one origin at the computer to connect multiple devices . <strong>FireWire (IEEE 1394)</strong> FireWire is a replacement for SCSI (small computer system interface) that commonly connected older PCs to printers and other external devices. Firewire has become the standard for transferring digital video. <strong>Thunderbolt</strong> is a hardware interface developed by Intel and first introduced by Apple that supports high-resolution displays and data devices.</a></faq_item></faq>', 'events_links' => null, 'resources_links' => null, 'date_created' => object(Cake\I18n\FrozenTime) {}, 'created_by_eai_user_id' => (int) 13659, 'date_modified' => object(Cake\I18n\FrozenTime) {}, 'modified_by_eai_user_id' => (int) 14231, 'category_1_video_url' => null, 'category_2_video_url' => null, 'category_3_video_url' => null, 'redirect_url' => null, 'parent' => object(App\Model\Entity\WebPage) {}, '[new]' => false, '[accessible]' => [ [maximum depth reached] ], '[dirty]' => [ [maximum depth reached] ], '[original]' => [[maximum depth reached]], '[virtual]' => [[maximum depth reached]], '[hasErrors]' => false, '[errors]' => [[maximum depth reached]], '[invalid]' => [[maximum depth reached]], '[repository]' => 'Parent' }, (int) 5 => object(App\Model\Entity\WebPage) { 'web_page_id' => (int) 1279, 'slug' => null, 'title' => 'Connections and Cables', 'short_description' => null, 'page_text' => 'Connections and cables are devices for moving analog and digital data in and out of the computer.
