You guys are over complicating it.... Highway analogy... Throughput = Speedlimit Bandwidth = Number of lanes Its that simple.. Add more lanes, increase bandwidth, increase the speedlimit, increase throughput..
Your analogy doesn't quite make sense because how can increasing the bandwidth (number of lanes) increase the speed limit of the highway? Forget about analogies. A bandwidth of 100 Mb/s means that a MAXIMUM of 100 Mb can be transferred in 1 second. Throughput is the ACTUAL amount of Mb that got transferred in 1 second.
No. Bandwidth is how fast data can go. 10G vs 100G. Which can SEND data faster? Throughput is the utilization. If i push 20G in a 100G link you would say bandwidth is low or throughput is low? Your post is overall wrong.
Woah, bandwidth is the "Width" of the "band" and throughput is the amount of data "put" "through" (the "band"). Did not make that connection until just now
Bandwidth equals number of fully populated lanes Throughput equals how many cars per second are currently traveling those lanes. Your analogy is off, but you probably know that by now.
In short: Bandwidth -> The current size of the data that is passed through the "cable" Throughput -> The maximum amount of data that can be passed through the "cable" Example: 4MB Images via a 100Mbps max speed cable: 100Mbps is 12.5MBps, which is our max speed == Throughput Sending the three images at the same time will lead to sending 4x3 = 12MB of data, which leaves us with 12.5 - 12 = 0.5MB throughput until the first image arrives and leaves space. Correct me if I'm wrong
You're right that bandwidth commonly refers to channel width of analog modulated continuous carriers. However, bandwidth IS an effective way of measuring "how fast a device can send data over a single cable" or any other medium. For a given modulation technique, a greater BW medium (cable in this example) can carry more encoded data. Additionally, the space between stations is not necessarily the channel BW, either. A lot of the EM spacing is guard-band.
Part 2. So given that we have to take out the "overheads for the lines to separate the lanes and a little space so you can drift over when spilling coffee on yourself or fiddling with the radio, and the soft-shoulder when you get pulled over by the cop for prior violation you are left with enough space for 4 cars which would be your throughput. So in a nutshell throughput would the the potential minus the overheads. How did I do?
hey bandwidth is not actually "speed". It's capacity of data transmitted over time. ie. 10megabits per second. You can measure speed by latency. how long does it take sending this amount of data from computer A to computer B. I usually measure it by ping. ie. 32ms sending one packet from computer A to computer B.
If this is the case, why is everything measured in "bits per second." Even bandwidth when discussed by the ISPs is measured in some number of bits per second. Based on this video, it considers bandwidth and latency to be basically the same thing but I guess the difference would be the latency depends on the destination whereas bandwidth could be a speed measurement independent of the destination of the data however it's still measured in bits per second, so what gives?
By my understanding, bandwidth tells you what the capacity is. Throughput tells you the speed of transmission through that bandwidth. The more bandwidth you have, the more throughput you can achieve. Latency on the other hand is about timing. i.e. how long it takes to transmit data from one end to another.
+Yiannis Serpico You may think like going down from hill, and climb to hill... As you guess, so much differences of speed on each task. it is just sample, do not match exactly same.
You're writing lots of things that are correct, but they don't reinforce the original comment that "BW has never meant 'how fast a device can send data over a single cable.'" That comment misleads readers because, in measuring optical multimode fiber carrying capacity, BW means precisely that. Look for Applications Engineering Note 81 by Corning Cable Systems (apparently I am not allowed to paste a link here; sorry).
Oh lord, I have to agree. It is what happens when you learn something and want to share it but do not yourself have a full grasp of the idea. My 2cents: So in the example of the Highway and the bandwidth. Bandwidth would be the total width of the highway or as you have correctly stated the potential/possible volume. Lets say the the highway was 30 feet wide and cars were 5 feet wide. The potential (bandwidth) number of cars that could fit in would be 6. See Next comment 2
@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
Sure! But I thought hot was used to describe temperature, and more specifically high degrees, whereas cold is degrees on the lower end. Am I missing a screw here? I mean, how does the Chinese girl relate to bandwidth. I know this comment was made 4 years ago, but we are still viewing the videos today and they have not closed off comments! Which Chinese girl, and how do you know she is Chinese? Can you look at a person tell if that person is an African or an American? I need help. MED, maybe:(
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.
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
please i need a video like this (not explanation video) shows peak to average power ratio reduction problem and its effect on OFDM signals ...... thank you
