<DIV dir=ltr><FONT face=Arial color=#000000 size=2>Russell, when I was going
through the exam with my pupils, I came up with the same thoughts on answers as
yourself. The information about the cable modems we commonly see now in homes
and business apps, is interesting to note. I think that since we often refer to
the current modems in homes as 'high speed', we tend to assume that they are
digital by default.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>I also picked modem instead of router for
the LAN/WAN question.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>Question 3, I agree, is worded in a rather
odd way making the 'right' answer a challenge to pick.</FONT></DIV>

<P><FONT size=2>Hi Mark, I agree with most of what you have said, just a couple
of <BR>minor points<BR><BR>On 15/10/2007, at 1:36 PM, Mark Kelly

indeed to enable communications <BR>between two or more networks. It may
include a firewall of some sort <BR>(=protection from the outside world)
but need not. A modem is not <BR>necessary as you may have a
data link that doesn't require modulation/<BR>demodulation-- though you'd be
hard pressed to find one that could <BR>offer distances that classify as
"wide area"!<BR><BR>> Question 3<BR>> Which type of backup uses two sets
of backup media and backs up the <BR>> most recent changes on the second
media?<BR>> Suggested answer: B. Differential.<BR>><BR>> This can’t be
right., The question is very odd. Two sets of <BR>> backup
media? From <A

20backup.htm...<BR><BR>I suppose what they're getting at is that incremental
backups might <BR>use more than twos set of media. But in fact, the terms
are about <BR>_what_ you backup, _when_ -- not _where_ you put the data
(i.e. media).<BR><BR>> A modem is, for most people today, a digital device
for ADSL or <BR>> cable internet that has no modulation or demodulation
happening! <BR>> The question should have referred to analogue
modems if it wanted <BR>> this answer.<BR><BR>No, ADSL and cable are
still analog modems. ADSL goes over copper <BR>line just as dialup, simply
using a much higher (analog) bandwidth <BR>than plain dialup and avoiding
the voice band. Cable modems (afaik) <BR>use an optic fibre data link so
again this is a modem, as a carrier <BR>wave (in this case a light wave) is
modulated to transport data. <BR>Even wireless, 3G or satellite
internet will rely on a pair of modems <BR>(with an electromagnetic wave as
a carrier) as part of the link, even <BR>though the term isn't usually used
in reference to them.<BR><BR>cheers<BR><BR>Russell Edwards<BR>Whittlesea
