Bandwidth is comparable to this. Bandwidth is the variety of frequencies that may be carried across a given transmission channel. The more guidance being sent, the more bandwidth is essential. A average analog cellphone line calls for 3 khz to deal with voice communications. The phone company truly breaks the electromagnetic spectrum into 4 khz slices.
These slices are limited with bandpass filters think spigot. Now this works well until we introduce data into the equation. At that time there isn’t enough capcity in the general phone line to address the additional suggestions that must be moved during the system. These amenities are can be likened to the fireplace agencies’ hoses and the firehydrant. They are Broadband Services.
In telecommunications, broadband refers to a system able to sporting a relatively big selection of frequencies. These frequencies can then be divided into channels. Each channel can then be used to transmit assistance. The more frequencies or channels, the more counsel can be transmitted. In other words, more frequencies equals a much bigger hose. This hose then connects to the central office of the telephone company or an even bigger spigot, much just like the fire hydrant.
This is why most companies are moving away from the typical dial up service and into either DSL, Cable Modem, Satelite or T1 provider. They are simply searching for a much bigger hose to put more information via in an effort to satisfy and extinguish the ever existing demand fire for more suggestions.
