<p class=MsoNormal><span style='color:#1F497D'>GB is definitely Gigabytes and
Gb is definitely Gigabits. The context does inform the unit though –
for example, even though in SBQ4 it does say ‘4 Gb RAM’ – you
would not be talking about ‘bits’ in the context of RAM.
Likewise in SCQ3 – ’40 Mb’ for a file size – would be
Megabytes as opposed to Megabits. Although it is probably easier for us
to be comfortable with errors like this and less so for students who are a
little unsure (and wary of trick – or “tricky” questions).<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-AU>One confusing point was the use of Gb for
Giga<b>bytes</b> of the hard drive and RAM (both in section B and C) and kbps
for presumably kilo<b>bits</b>. I am sure it should be a capital B for bytes
and a small b for bits. This confused some of my students (although I think
they made the correct decisions). Perhaps this ambiguity needs to be taken into
account by the examiners for section C question 4 and 5. <o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN>“The <b>gigabyte</b> is an <a

of the unit <a href="http://en.wikipedia.org/wiki/Byte" title=Byte>byte</a> for
<a href="http://en.wikipedia.org/wiki/Computer_data_storage"
title="Computer data storage">digital information storage</a>. The prefix <i><a
href="http://en.wikipedia.org/wiki/Giga-" title=Giga->giga</a></i> means 10<sup>9</sup>,
therefore 1 <i>gigabyte</i> is 1000000000bytes. The unit symbol for the
gigabyte is <b>GB</b> or <b>Gbyte</b>, but not <i>Gb</i> (lower case <i>b</i>)
which is used for the <a href="http://en.wikipedia.org/wiki/Gigabit"
