i googled for it but could not exactly find the origin of the world 🙂
 
shall i tell you why... 😉

coz it gives
BBBBBBBBRRRRRRROOOOOOOOAAAADDDDDDDDEEEEEEEEERRRRRRR
Bandwidth
😛 😀 :lol:

right buddy..? 🙄

But theres BROADER than Broadband bandwidths.....
 
Broadband is a synonym of "Wideband". These are engineering terms.

In engineering terms, any medium is Wideband if it can carry a "big band" of frequencies.

For example, in older days cables used for TV could carry only a few MHz of frequencies, that limited number of channels that could be transmitted over those cables. If you transmit more channels there will be a crosstalk and voice/video of one channel might mix into another.

Cables that are used today can carry hundreds of channels simultaneously.

A typical TV channel requires 6 MHz band. So any transmission medium that can carry frequencies from 500 to 600 MHz can carry 16 channels at max.

Another medium that can carry frequencies from 500 MHz to 1000 KHz (1 GHz) can carry much more channels.

A diagram of band usage in US is given here : http://www.ntia.doc.gov/osmhome/allochrt.pdf


So Broadband is any medium that can carry large amount of information.

In digital terms that translates to any medium (cable/DSL/VSAT/....) that can carry large amount of data.
 

broadband means wide "band". Band is a range of frequencies used for communication. Some communication methods such as FM use a few KHz above and below the frequency assigned to them. For example, 98.3 FM uses a few KHz above and below 98.3MHz to transmit their signals. Broadband uses the same principle except the the "range" of frequencies are quite wide. Thats why its called _broad_ band. It has no implications whatsoever on the "bandwidth" or "download" speeds that we get. The speeds could be 64Kbps and still it can be termed as "broadband".
 
Probably we were typing at the same time with nearly the same content.
 
You guys know so much.... I am probably the Oldest and the DUMBEST in the forum... So I am looking for the dumbest answers... Just Like Me.....
 
We just happen to be engineers. And like any other profession, insider terms do not make any sense to general public.

This page does a better job.

Bandwidth has now become a standard English term. In US its common to say "Does your team has enough management Bandwidth to handle new project" In this sense bandwidth means capacity.
 
One interestign fact is, Broadband DOES NOT mean fast (In strict engineering terms). I remember one discussion from one of engineering books. A train (or truck) has better bandwidth then Fiber optics. 1 Cubic meter of space can pack 1,40,000 DVDs (DVD has 12 cm diameter and takes 5 mm of vertical space to pack)1 bogie of train has approx dimensions of 10 meters length and 2 meters height and breadth. That makes the volume to be 40 cubic meters. 1 train can have have 20 such bogies.Ultimately, 1 train can carry 90 PB (Petabytes) of data. Assuming that each DVD has 9 GB data. A train running between Delhi and Mumbai can cover distance in 18 hours. Its bandwidth would be 1.4 TBPS... and that Tera Bytes not Tera BitsImagine a web page that takes 18 hours to load, but the bandwidth could still be 1.5 TBPS.
