I was wondering about that but 1200 Kbit/sec (150 KB/sec) seemed a little
low as a max on cable modem... computers use base-2 as their numbering
system so kilobyte, megabyte, gigabyte are all multiples of 1024 rather than
1000; though, to make things confusing, companies often use base-10 for the
various denominations of bit and at other times base-2 (which is why your 40
"gig" HD doesn't actually format to a true 40 gigaBYTES)) (PS I didn't
realise you were in K/W Eurogarth)
1200 Kb/sec ~ 150 K/sec (aka KB... Kb is only used by marketing firms trying
to make their 1 megabit modems seem faster than they really are). My little
bro's had cable modem for the past 6 months in K/W and he was disappointed
with the speeds he'd get compared to what I got in London (typically he gets
20-80 K/sec IIRC)... although he was doing better than our friend with Ma
Bells Symcrapico Low-Speed-Edition (her nickname for the company) who was
jealous of his access... jealousy seems to stop with our father... he's
happy on 56K & I don't think I could even handle a downgrade cable modem
anymore (too slow ;-P ;-P ;-P)).
PS How fast are the modems used with cable? 4 megabit? (I assume since I've
seen ~400 K/sec which would jive with the overhead required over a 4 megabit
connection)
