confusing internet speed!?

[alireza Yousefi]

hi
my internet speed in speedtest.net is around 900kb/s but in internet dl manager it doesnt go more than 120kb/s!im sure that no one steals my internet and im sure that no application uses all of my speed!i called isp but they said that my internet connection is working properly but my guess is that isp is sharing my internet connection!what should i do?is there anyway that i can boost my internet speed?im in iran.....

Your internet speed and downloading speed are different things..
The reason why the download speed is 120kb/s varies on whichever source you're downloading from.
Try downloading from another site/url.

Are you sure your not getting confused with Kbps and KBps

Internet speed is normally measure in Kbps (KiloBITS per second), where as downloading programs normally measure in KBps - KiloBYTES per second.

1 Kilobit is 1024 Bits ( in data a single binary character is a Bit ( 10111101 is 8 bits of data)
1 Kilobyte is 1024 Bytes (in data 8 bits make one byte - so 10111101 is 1 byte)

1 kilobyte / s = 8 kilo bits per second so 900 kilobits per second would give you a download speed of just over 100 kilobytes per second - which is what your getting.

Google converson from Kb/s to KB/s says 900Kb/s is equivalent to 112.5KB/s which seems very close to what your getting (your possibly exceeding 900kbps slightly

what type of internet connection do you have? DSL? WIFI ? What is the download speed you are suppose to have?
