<p class=MsoNormal>In the questions from the end of chapter 1 and question 2,
we are required to convert between bits, bytes, megabytes, megabits, gigabytes,
and gigabits. My understanding (from CS 61C) is that telecommunications (such
as the internet) use base 10 as a conversion between many of these various
units. For example (note that a capital B = bytes and a lowercase b = bits)<o:p></o:p></p>
<p class=MsoNormal>1 Kb = 10^3 b<o:p></o:p></p>
<p class=MsoNormal>1 Mb = 10^3 Kb = 10^6 b<o:p></o:p></p>
<p class=MsoNormal>1 Gb = 10^3 Mb = 10^9 b<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Furthermore:<o:p></o:p></p>
<p class=MsoNormal>1 B = 8 b<o:p></o:p></p>
<p class=MsoNormal>1 KB = 10^3 B = 8*10^3 b<o:p></o:p></p>
<p class=MsoNormal>1 MB = 10^3 KB = 10^6 B = 8*10^6 b<o:p></o:p></p>
<p class=MsoNormal>1 GB = 10^3 MB = 10^9 B = 8*10^9 b<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>It was under these conversion factors that I did the first
half of problem 1. When I reached problem 2, I noticed that it says “(Note:
1 KB = 2^10 bytes, 1 Mbps = 10^6 bits/s)” These two appear to be
contradictory, as one conversion uses base 2 and the other uses base 10. I
thought that 1 KB = 10^3 bytes, not 2^10 bytes! Of course, if we are talking
about data storage, then 1 KB could equal 2^10 bytes, however, don’t we
prefer the IEC notation 1 KiB = 2^10 bytes?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve already switched my homework from base 2 to base
10, please let me know if I need to switch back!<o:p></o:p></p>
