Quote from: Jessica I get confused between MB/s kbps mbps etc etc.
Hi Jessica,
Haven't we all at some time or other?
MB/s or MBps is Mega Bytes per second
Mbps (I'm sure you meant big "M" not little "m" see below) is Mega bits per second
kbps is killo bits per second
1 Byte = 8 bits
M = 106 - 1,000,000
k = 103 - 1,000
m = 10-3 - 0.001
1Mbps = 1000kbps
Note the above are decimal interpretations of M and k - I'll not bore you with the binary (2x) equivelents...
Lovely picture by the way.
Kevin

The fastest I can download is 9.37MB/s. Is that correct for a 74.78Mb/s connection? Seems slow to me.
Thanks

Have a look at http://community.plus.net/forum/index.php/topic,129947.msg1131202.html#msg1131202 as Townman has explained really well the differences between Mb/s and MB/s.

It is also unlikely that the usenet server is saturating your connection in the same way a speed tester is.

The synch speed is the total capacity of the line in bits. These speed test tells you how fast you can move BYTES of DATA.
Working out the USEFUL BYTE RATE is not as simple as dividing the bit rate by eight as in 1byte = 8 bits. A data file is not sent in one limp. It is split in to fragments and sent across the network as packets.
For argument's sake, let's say that a fragment is 1000 bytes, to send a 1M byte file, there will need to be 1000 fragments wrapped up in "packet envelopes" and sent across the network.
Every fragment needs to be wrapped with a header and error check data. That then needs to be wrapped with protocol control information - source / destination addresses, sequence number, status info and more error checking before being transmitted through the Internet.
When that packet hits your link, there has to be additional line control messages to acknowledge receipt, request retransmission and to generally control the link and keep it alive.
All of this essential control and management utilise some of the raw bit rate, resulting in a smaller capacity for the actual data. This is why the line's "profile" is always lower than the raw synch speed.
On 21CN ADSL services, 11.8% of the synch rate is "reserved" for line and protocol management needs. Getting around 95% of your synch rate in data through put is truly cooking on gas!
