Bandwidth vs. Throughput

Educational video describing the differences between Bandwidth and Throughput. Very good information to anyone learning networking.

Terrible script. Bandwidth refers to the maximum potential volume. Throughput is the actual volume.

Thanks for the input.

Bandwidth has NEVER meant "how fast a device can send data over a single cable". That is simply the speed or the throughput. Bandwidth means EXACTLY what it says, how wide a e.g. frequency band might be. E.g. commercial radio frequency. In the US the bandwidth between stations is 200MHz, in Europe it's 25 MHz. I.e. the bandwidth in Europe is narrower (the band-w i d t h is narrower) than in the US. Hence your receiver in the US jumps from e.g. 97.3 to 97.5. In Europe from 97.3. to 97.325 MHz.

Thanks for the throughput

bandwidth = Amount of data per unit of time.

so if you internet has a download bandwidth of 10mbit per second, then it means that you can download data at a maximum speed of 10 mbit per seconds.

Im not really sure about throughput but see it as the amount of data that can be redirected.

For example accesspoints, they might have a throughput of 300mbit per second, meaning that it can take signals from a wifi transmitter, contain it for a very short period of time, amplify it, and retransmit it.

lol this video is wrong

@markyannone yep, that's exactly what he said... were you even watching the same video as me?

This is often a very, very bad idea. I once went to a Novel Network class (holy crap, I'm dating myself, aren't I?), and the teach insisted on using analogies for everything; but I don't think he really understood that analogies only work if you can relate them to the actual topic at hand. His attempt at spoon-feeding really just made me more confused. Later a tech friend just gave me the technical explanation and I got it immediately.

Oh I see, well I've been learning that material now inch by inch in my program called "Game Development and Entrepreneurship". Yes I dream of making games, artistic games at that! :D

I've been programming in C++ for about a year and a half now. I've also made a game in that language, you want me to send a copy to you? It's free, and no virus haha! :P

@GameIndustryAnalyst A study program, very good!!! I'm working in service prodiver networks for some years now, so I'm only acting in one little edge of the digital world. There's such cool things to learn for us, physical technology, OS, programming, hardware design, troubleshoot/support/fault management, software design, PC or server, mobile or stationary devices, periphery, network, web,.... etc etc

[GameIndustryAnalyst]

@TheRiker1982 Okay I'll take your word on that, especially given the fact that I only have a basic knowledge of computer architecture... :S

I'll be learning more about networking next year in my university program. :P
