"Most computers allow you to hook up external speakers using the sound output jack."
Speakers are popular output devices used with computer systems. They receive audio input from the computer's sound card and produce audio output in the form of sound waves. Most speakers for computer are active speakers, meaning they have an internal amplifier which allows you to increase the volume, or amplitude, of the sound. Speakers usually come in pairs, which allow them to produce stereo sound from two separate audio channels.

Getting Better All the Time
Starting in the 1990s, vendors began to offer higher-quality computer speakers. Similar to home theater and stereo systems, many computer speaker systems include a pair of small speakers for the midrange and high (treble) frequencies and a large subwoofer for the low end (bass). The small speakers are placed in a left/right stereo orientation, while the subwoofer can be located anywhere on the floor because bass signals are unidirectional. See sound card and subwoofer. Speakers typically come in pairs, which allow them to produce stereo sound. This means the left and right speakers transmit audio on two completely separate channels. By using two speakers, music sounds much more natural since our ears are used to hearing sounds from the left and right at the same time. Surround systems may include four to seven speakers (plus a subwoofer), which creates an even more realistic experience.
