TwiztedZero posted : 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.

Bandwidth's definition has been extended ...

By whom?

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.

said by s_tux_g:

... it can be any other unit of time (9GB/day, 300GB/month, etc...)

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

Says who?

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".

9gb for yesterday upload n download together, I do not leave my pc running when I am not using it, i have yet to test if counter goes up when not online. As for the virus/trojan/spyware doubt it because I do weekly scans (avg, malwarebytes, etc and did not notice any program running in background that could be like constantly updating itself or something, will have to double check).

Sorry for the typo, I meant to ask if it was up OR down... 9GB up is very different than 9GB down... To answer your original question, I find TekSavvy's counter pretty accurate. My router monitors bandwidth and the reports are always 2-7% above that (router stats don't include overhead).

Teddy Boom posted : 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.

TSI Support2 posted : Hello Reboot123,

I have checked several other customer's usage and could not find a common fault or inconsistency with May's usage. It is certainly weird how the usage would be so much higher. I do see it was for the most part evenly distributed on each day of the month. I would check into there being any kind of virus or spyware that may have gotten onto your computer(s). As you said it's definitely not someone leeching off wireless so we must look elsewhere.

Thank you,
TSI Rizwaan

Reboot123 posted : Hi, last month my bandwidth went up to 259GB (I am on the 300GB plan), usually I have round 70GB monthly, was wondering if the teksavvy usage monitor is 100% accurate, its the 1st time I get this much and also wondering if the use of tiny chat has a considerable impact on bandwidth. (edit: for yesterday and today it already shows 9GB which is weird since the only thing that was mainly used is tinychat)(I think I will do a test and not use net for a day lol and see if it still goes up, also it cannot be someone leeching on the net, because I do not have wifi, everything is wired).
Thank you
