Re: Bandwith

In your case you probably don't even have to give up the net for a day, at least not yet. Just unplug the network cable running to your modem whenever you walk away from the computer, and plug it in again when you want to do some stuff. If something undetected is using your line, the usage stats should go down enormously doing that.

(I hate that Teksavvy uses "bandwidth" for this.. Bandwidth means speed. This conversation is about usage)

Bandwidth's definition has been extended to also mean the amount of data that can or is transmitted per unit of time. The unit of time is often a second (e.g. 100mbps), but it can be any other unit of time (9GB/day, 300GB/month, etc...)

Although speed is widely recognized as meaning the max data rate of a connection, its use is totally incorrect. I guess marketing "experts" thought "Hi-Speed" was catchier than "High bandwidth" or "High throughput".

By whom?

Wrong. In computer science bandwidth is always measured in bits per second.

Not by me... From the American Heritage Science Dictionary:
    The amount of data that can be passed along a communications channel in a given period of time.

The original, correct meaning is:
    The numerical difference between the upper and lower frequencies of a band of electromagnetic radiation, especially an assigned range of radio frequencies.

Bandwidth
said by Wiki :

•Bandwidth sometimes defines the net bit rate (aka. peak bit rate, information rate or physical layer useful bit rate), channel capacity, or the maximum throughput of a logical or physical communication path in a digital communication system. For example, bandwidth tests measure the maximum throughput of a computer network. The reason for this usage is that according to Hartley's law, the maximum data rate of a physical communication link is proportional to its bandwidth in hertz, which is sometimes called frequency bandwidth, spectral bandwidth, RF bandwidth, signal bandwidth or analog bandwidth.
Bandwidth Capacity

•Bandwidth in bit/s may also refer to consumed bandwidth, corresponding to achieved throughput or goodput, i.e., the average rate of successful data transfer through a communication path. This sense applies to concepts and technologies such as bandwidth shaping, bandwidth management, bandwidth throttling, bandwidth cap, bandwidth allocation (for example bandwidth allocation protocol and dynamic bandwidth allocation), etc. A bit stream's bandwidth is proportional to the average consumed signal bandwidth in Hertz (the average spectral bandwidth of the analog signal representing the bit stream) during a studied time interval.
