ok, but i'm thinking if i get 0.8mbps from my 2mbps connection,i should get much higher speed with 20mbps! that could reduce the lag..and i did the math,
speed of light=3*10^8m/s
distance=10000miles(say) =16100km=16100000m
so time @ speed of light =16100000(m)/300000000(m/s) =53ms ....what am i missing here??
umm.. speed here reflects the quantity of data flowing into ur computer per second..i know its like comparing oranges to apples but you can visualize it in the form of water being fed into your house by a pipe..when your speed increases the size/width of the pipe increases bringing in more water per second but the speed at which water was flowing remains constant..similarly there is certain time that data packets need to travel over the network..even in best case scenario without any congestion, there is a certain inherent latency of each network which cant be beaten irrespective of the speed of the connection.
latency would vary with the type of network..for eg dial up versus fiber..fiber would be better..but when u already have a fiber connection and opt a faster speed on the same network, ur latency would not necessarily improve..
