KB vs Kb vs MB vs Mb

Post by KillerBob »

Hi,

I apologize for my ignorance, but please help me out here:

In the lower left of the UE screen it says the current bandwidth is 329 KB/s, and I was just wondering if that is acceptable on a stated "2400 Kbit/s" connection?

If I understand it right, then 2400 Kbit/s is equal to 307 KB/s, in which case this is very good indeed!

yes KB means kbytes.

i'm also not a pro in these things, i think for some time it was "kb" in newspro to save a little space, but then someone pointed me to the difference :)

1KByte contains 1024 bytes and 1 byte contains 8 bit so 329KB/s is 329*1024*8=2695168 bit or /1024 = 2632kbit per second (1kbit i guess it is 1024 bit). 1MB contains 1024KB or 1024*1024 bytes, so when you see 0.99MB it means more than 1 million bytes.

ue is quite a fresh code which was optimized for speed for more than contemproray usenet volume given conventional newsreader use (since nzb, indexing services don't put much load on newsreaders, conventional use is the area where perfomance is usually an issue), comparative to ue newspro has a weaker performance on header tasks when newsgroups get large (but not article tasks which are always fast) because the code was written before the usenet volume exploded.

read for example this:

and:

so: KB is good for kilobyte(s)
Kbps is good for kilobits per second
