Now, if you replace this highway with a 20 lane highway, suddenly far more cars can drive on this road, allowing for far more cars in total. If there's only a 2 lane highway, once the traffic reaches a certain amount of cars, a traffic jam will occur, meaning, a certain number of cars can drive on this road without congestion, but not too many. There is lots of car traffic between the cities. So this will increase the ping time (latency) but not affect the speed.Īn analogy: Lets assume you have 2 cities. If you have lots of bandwidth but the speed itself is slow (for example, your data travels all across the world, or you use a 56k6 modem or other slow device, or other factor that makes the connection slow) you can still exchange a lot of information at the same time, it just takes longer to arrive. So even if you have a wide bandwidth, you are bottlenecked on the other side. If the other side of the connection has a small bandwidth, then that will make the entire connection slow as only few packets per second can be exchanged. That said, if your bandwidth is big, it can send a lot of packets at the same time, but its not a guarantee that this will actually happen. So if the bandwidth is very low, only very few packets are sent at the same time. The bandwidth means: how much packets can be sent at the same time. The more packets are sent, the more bandwidth you use, but also the faster your connection is. When you connect to a server and you initiate a data transfer, packets are sent simultaneously every second.
