[Year 12 SofDev] Exam - Section C - Discussion

[Matheson, Heath A]

No surprises in the exam which is nice.

 

One confusing point was the use of Gb for Gigabytes of the hard drive
and RAM (both in section B and C) and kbps for presumably kilobits. 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. 

 

>From the sometimes unreliable (but quick to access) Wikipedia:

"The gigabyte is an SI <http://en.wikipedia.org/wiki/SI_prefix>
-multiple of the unit byte <http://en.wikipedia.org/wiki/Byte>  for
digital information storage
<http://en.wikipedia.org/wiki/Computer_data_storage> . The prefix giga
<http://en.wikipedia.org/wiki/Giga->  means 109, therefore 1 gigabyte is
1000000000bytes. The unit symbol for the gigabyte is GB or Gbyte, but
not Gb (lower case b) which is used for the gigabit
<http://en.wikipedia.org/wiki/Gigabit> ."
