Cable modem |
| |
|
A communications component that
makes possible broadband connections online by means of cable television
technology. Accessing speeds differ significantly, depending of several
factors such as the amount of Internet users at that time of accessing,
the speed of the modem or even the telephone wire connection in the
house where the connection is established. Cable modems can operate with
a transfer velocity of 10 megabits (Mbps) per second. |

Cable TV |
|
|
|
Cable TV was originally called
Community Antenna Television (CATV). It is designed to operate as a
communications system competitive to distribute broadcasted programming
and some personalized content and services by using coaxial cable
technology. |

Cathode Ray Tube |
| |
|
Also known as CRT, this
technology is being replaced by plasma, LCD and similar more compact
display technologies. CRTs are analog monitors that display the picture
on phosphors layers which are activated by an electron gun. |

Re-writable CDs are very
convenient for some uses, but they are not recognized and played by many
CD players out there. |

Center channel |
|
|
In a Home-Theater system, that
is the speaker installed in the front-center, and which is dedicated to
reproduce the sounds that are meant to come from the screen, such as
voices, focused subjects and some music. Place this speaker as close to
the screen as possible. |

Coaxial cable |
|
|
A type of top-quality cable used
in Home-Theater systems’ connections; the cable has an internal
conductor enclosed by a braided-like conductor which performs as an
interference shield. Coaxial connections are to be used in Home-Theater
systems whenever and wherever possible; the coaxial cable costs a bit
more than average quality cable, but the performance quality of
coaxial-connected DSS, TV, VCR, antennas and other components is greatly
enhanced. |

Commercial skip function |
|
|
A feature found in recording
components such as a VCR; it allows skipping TV commercials by
fast-forwarding 30 seconds of the recorded data, this time frame is
selected because most TV commercials last an average of 30 seconds.
Using a remote control, the user would have to press the Commercial Skip
button a few times until the commercials are finished and the desired
program appears on-screen again. |

Compact Disc |
|
|
An optical storage format for
digital data; the data can be formats like JPEG, MP3, text, audio and
video, among others. CDs are clear discs with a 5-inch diameter, coated
with a resin protective film over an aluminum reflective film bonded to
the disc; CDs are resistant and non-magnetic and they are able to store
700 MB on a single side, which can be represented as 80 minutes of
audio. The Compact Disc technology then divides and dives into more
specialized tasks and topics; some CDs are meant to be DC-R or CD-RW
compatible; or others are DVD-RWs or DVIs, but all formats provide when
recorded properly, frequency-unaltered, noiseless, high-fidelity sound
and neat image quality not easy to beat with other recording formats.
The disc is durable and only minor maintenance is required to it, but
never affix labels or tape to the actual CD; to label CDs, use a marker
instead. |
