Please prove my friend he's a dumb dumb....

My friend thinks that you can get 90kb/s on Imesh with 56k. That is completely false right guys?

[deanjamin]

Erm...yes. The theoretical max on 56k is 8KB/s and you'd struggle to get that

[TiG]

theoretical maximum on a modem is 7KB/s

This is with compression used on the transmission lines of a 56k modem, theoretical physical maximum without compression is 33.6k i believe.

So no its not possible.

Depends what he was looking at, one of my friends used to get 120k/sec on newsgroup header downloads on ntl, but that was purely the data compression (massive repeation of a small ascii segment).
Occasionally you'll get IE doing it's sums wrong when it starts a download from the sudden burst of data and reporting silly speeds (I'm on 512kb adsl with a maximum of around 59/60kb/sec, and sometimes when a download starts IE reports silly download speeds, 300kb/sec in one case but it soon dropped to the expected speed), but as TiG says, the maximum sustainable rate is around 7kb/sec on a very good 56k line, if you're lucky.

Ex:

[Austin]

The fastest std phoneline modems ten to send at 33.6Kb/s and recieve at 33.6Kb/s (increased via compression which will vary by data to 56Kb/s). Dop rem that we're dealing with Kbits rather than KBytes, there's 8 times the diff there and many Fileshare Programs neglect to specify whether you're in bit or bytes. So 33.6Kb/s is 4.2KB/s and 56Kb/s is 7.0KB/s, networking stuff and ROMs usually use the bits notation while HD's, RAM, CD/DVD etc tend to use bytes. So basicly no, there's litterally zero chance of getting above 56Kb/s and factoring in limitations of compression and real world conditions the average is more likely 45Kb/s. IIRC you can improve the 33.6Kb/s sending speed to around 44Kb/s (again theoretical compression) but I believe you need ISP support and they're no longer bothered about slow modem upgrades.

http://bandwidthplace.com/speedtest/index.html <-- my result = 5.4 megabits per second
http://webservices.cnet.com/bandwidth/ <-- my result = 2232 kbps
http://us.mcafee.com/root/speedometer.asp <- my result = 4.335 Mbps (554.84 KBps)

Tell him to run a speed test like in the links above. There's hundreds of them out there on the net. The ones above I think are some of the better ones.

ok

56k =7k second
512k=64 k second

of course this varies and can go up and down

but is the general speed


no way 90k on imesh, maybe 90kBIT which is 12 or so K, this can be had from compression, i once downloaded at 20kb per second on 56k, this was down to complession as i was downloading a text file, albeit it was a large text file (4mb) once in winzip it was 1mb, 1/4 of the size therefore 4 times the speed

if it was a mp3, or a video which are relatviyl uncomrpessable then hes lying, text or similar (ebook, pdf??) then maybe, but unlikely

[KraniX]

LOL 90Kb on a 56k modem, bwahaha, this is gonna keep me laughing all night long.

there should be laws for people like your mate catattack, laws forbidding him the right to breed for example.

Don't forget the 56Kb / 7KB std modems rely heavily on compression and perfect world conditions for that whereas 512Kb / 64KB broadband connections deliver exactly that all the time (bugs, service lapses etc to one side).

[bsodmike]

hahah.. dumbest thing i've heard in ages. I hope he knows the diff between bits and bytes but I guess not! *cough* looooser

However, 90kb/s != 90KB/s. 90/8 = 11ish KB/sec and still is high....

b = bit
B= byte
so mb Mb are the same thing but mb and mB or MB are diff

Actually the SI units mb and Mb are different.

mb would mean milli-bits
Mb would mean Mega-bits.

[Swafe]

in my book Mb means megabyte

i hate how they use bits and bytes when they feel like it

mega confusing ! there should be some standards..

There are, search for systeme internationale. m means milli. M means mega. b means bit(s). B means byte(s).

[TiG]

I'm with Richard on this one,

TiG

[Axion]

there are standards... hence s.i. units.... however loads of publications dont actually stick to them are happily skip between Mb, MB, KB, Kb, kb, mb without thinking twice!

basically anything internet/intranet related is most likely in bits to con you into thinking you've got some Mspeed (get it?)... and everything thing ram/hdd etc. related tends to be fairer and in bytes...

...although having said that hdd's are measured metrically and not by their native binary... so a 2gig hdd is 2000000000Bytes... (2x10^9) although in reality it should be 2*1024^3.... which is 2147483648Bytes... so we are getting conned out of ~ 6.9%

not fair eh?

[St3v3]

LOL, more like 90bytes/sec.

There has only been one time where I've saw info going at 90k/sec on 56k and that was with plain text or an ISO file that has empty space on it.

I love my bb, would neva wanna go back to 56k
