Bandwidth,+Broadband

media type="file" key="bandwidth.MP3" There are two types of bandwidth. The first type is in computer networks, bandwidth is often used as a synonym for data transfer rate - the amount of data that can be carried from one point to another in a given time period (usually a second). This kind of bandwidth is usually expressed in bits (of data) per second (bps). Occasionally, it's expressed as bytes per second (Bps). A modem that works at 57,600 bps hastwice the bandwidth of a modem that works at 28,800 bps. In general, a link with a high bandwidth is one that may be able to carry enough information to sustain the succession of images in a video presentation.

It should be remembered that a real communications path usually consists of a succession of links, each with its own bandwidth. If one of these is much slower than the rest, it is said to be a bandwidth bottleneck.

The second type is in electronic communication, bandwidth is the width of the range (or band) of frequencies that an electronic signal uses on a given transmission medium. In this usage, bandwidth is expressed in terms of the difference between the highest-frequency signal component and the lowest-frequency signal component. Since the frequency of a signal is measured in hertz (the number of cycles of change per second), a given bandwidth is the difference in hertz between the highest frequency the signal uses and the lowest frequency it uses. A typical voice signal has a bandwidth of approximately three kilohertz (3 kHz); an analog television (TV) broadcast video signal has a bandwidth of six megahertz (6 MHz) -- some 2,000 times as wide as the voice signal.([])

__**Broadband **__

In general, broadband refers to telecommunication, in which a wide **band **  of frequencies is available to transmit the information. Because a wide band of frequencies is available, information can be multiplexed and sent on many different frequencies or channels within the band concurrently, allowing more information to be transmitted in a given amount of time (much as more lanes on a highway allow more cars to travel on it at the same time). Related terms are wideband  (a synonym), **baseband **  (a one-channel band), and **narrowband ** (sometimes meaning just wide enough to carry voice, or simply "not broadband," and sometimes meaning specifically between 50 cps and 64 Kpbs). It is generally agreed that Digital Subscriber Line (DSL) and **cable TV ** <span style="background-color: #ffffff; font-family: Calibri,Helvetica,Arial,sans-serif; font-size: 16px;"> are broadband services in the downstream direction. <span style="background-color: #ffffff; color: #0000ff; font-family: Calibri,Helvetica,Arial,sans-serif; font-size: 16px;">News article - []
