25
A hardware device that most commonly enables multiple computers to be viewed and controlled by a single mouse, keyboard, and screen. Some reverse that capability, enabling a single computer to be controlled by multiple keyboards, mice, and other devices
Keyboard, Video, Mouse (KVM) Switch
26
Enables users to paint, ink, pencil, or otherwise draw on a computer. Received input using a special surface
Digitizer/Pen table
27
A process in which computers capture/record sound waves in electronic format. In simple terms, it means capturing the state or quality of a particular sound wave a set number of times each second. Measured in kilohertz (KHz)
Sampling
28
Loudness
Amplitude
29
How high or low the tone
Frequency
30
Qualities that differentiate the same note played on different instruments
Timbre
31
Measurement of the number of characteristics of a particular sound captured during sampling
Bit depth
32
Sound capture recorded at 44.1 KHz with 16-bit depth and in stereo
CD Quality
33
Sound format developed in the 1960s to carry telephone calls over the first digital lines
Pulse Code Modulations (PCM)
34
File format for audio faithfully recorded using the PCM format; produces very large file sizes
WAV
35
Broadcast of data that is played on your computer and immediately discarded
Streaming media
36
Interface between a computer and a device for simulating musical instruments. Rather than sending large sound samples, a computer can simply send “instructions” to the instrument describing pitch, tone, and duration of a sound. Because this file is made up of a set of instructions rather than a copy of the sound, modifying each component of the file is easy. It is possible to program many channels/“voices” of music to be played simultaneously, creating symphonic sound
Musical Instrument Digital Interface (MIDI)
37
Powerful speaker capable of producing extremely low-frequency sounds
Subwoofer
38
Nomenclature for multiple speakers that follows a simple format in which x is the number of satellites with 1 subwoofer
X.1 system
39
Part of a connector into which a plug is inserted
Jacks
40
A special connector that enables you to connect a sound card directly to a 5.1 speaker system or receiver. Comes in both a coaxial version and optical version
Sony/Philips Digital Interface (S/PDIF or SPDIF)
41
Software that compresses or decompresses media streams
Codec
42
File containing 2+ separate, compressed tracks, typically an audio track and a moving-picture track
Container file/wrapper
43
Codec used for DVDs and broadcast TV
MPEG-2 Part 2
44
Codec used for everything from smartphone video and streaming video to Blu-Ray movies
H.264
45
Codec that is half the size of h.264 at the same quality, used to support 4k video
H.265
46
Google’s competitor to h.265, codec used in places like Android devices and YouTube
VP9
47
