Where is my bandwidth going?

I use gprs connection to connect to the net. DU Meter shows my speed as 3 - 10 KB/sec whereas Opera 9 shows d speed as 0.5 - 1.5 KB/sec. There are no updates in process (NAV, ZA and Windows Updates are not taking place). In this case which application is eating into my already mearge bandwidth?

happens with me aslo ... i think what DU meter shows in kbPs

ea readermaniax is correct you must hav set dumeter to show BW in kbps where as opera shows bw in kBps

Dumeter has the several options of displaying speed, use wat is apt for u !!

R

now i have changed kbps to kb/sec

opera shows KB/s whereas dumeter shows kB/s. is thr a difference betn KB and kB?

@Akshay No man

Kbps and KB/sec
Kbps = KB/sec this is the same

next.. the meat and potatoes..
6-8 Kb/sec = estimated/calculated/approximated download speed..
translates to 6Kb*60 seconds = 360Kb/min (roughly 33% or 1/3 MB)

1 MB = 1024 KB = 1.048.576 bytes
5 MB = 5120 KB = 5.242.880 bytes
1 min = 60 sec = 1/60 hr
11 min = 660 sec = 11/60 hr

5.242.880 bytes / 660 sec = 7943.7575757575757575 b/sec

convert to kilobytes..
7943.757575757575757575 bytes / 1024 = 7.757575 Kb in one second

so your estimate of 6-8Kb/sec is right on and 11 minutes is about right.

synopsis:

1TB = 1024GB = 1.048.576MB = 1.073.741.824KB = 1.099.511.627.776 bytes.. not bits
thats next..

any of the above TB, GB, MB, KB, bytes etc.. etc.. multiplied by an amount of time
equals amount/time e.g. : Kb/sec or b/sec

now for bits vs bytes..
8 bits to 1 byte

the letter 'A' in ascii is represented as a binary value of '01000001' <see all 8 bits?
so the letter 'A' = 1 byte or 8bits

@readermaniax ..
can you explain to me .. what exactly have you written here.

as far as i can understand .. it's totally and entirely incoherent.

who's estimate... who said 11mins !

ughh .. what ?

I dont think anybody was confused in that ... 'ps' in 'kbps' is 'per second'
so .. kbps has to be same as kb/sec

I think you got it all wrong.

Let me try to explain the same thing.

1st thing ..
bits = represented by small "b"
bytes = represented by capital 'B"
1byte = 8bits

So, most probably your Opera is showing ~1KBps and your DUmeter is showing ~8Kbps
and 1KBps=8Kbps .. so everything is alright .. nothing is lost

Coming to the more confusing part ..
small "k" = 1000
capital "K"= 1024

So, 1kbits = 1000bits
but 1Kbits = 1024bits
Same logic doesnt necessarily apply to capital/small "M" for megabits or megabytes
Although it's not formally suggested .. but widely accepted that small k=1000 and capital K=1024
It's just a convention ..

Usually .. network speeds are expressed in 1024 multiples ..
ie 1Mbps = 1024Kbps = 1024*1024bps
RAM sizes are also expressed in 1024 multiples
But harddisk sizes are expressed in 1000 multiples.. ie. a 40GB drive has 40*1000*1000*1000 bytes.
(note that it has capital "B" .. hence bytes .. not bits)
Just a convention !!

Hope I made things clear.
