+ <p>Answer this question, quite briefly.</p>

+
+ <p>The memory and disk space statistics are displayed using <em>IEC binary
+ prefixes</em>, KiB, MiB, GiB, TiB (for kibi, mebi, gibi and tebi). These are
+ intended to distinguish binary reporting of sizes used in System Monitor
+ (multiples of 1024) from decimal sizes (multiples of 1000) commonly used, for
+ instance, in packaging of hard disks.</p>
+
+ <p>Typical binary units:</p>
+ <list>
+ <item><p>1 KiB = 1024 bytes</p></item>
+ <item><p>1 MiB = 1048576 bytes</p></item>
+ <item><p>1 GiB = 1073741842 bytes</p></item>
+ </list>
+
+ <p>An external hard drive, advertised as 1.0 TB (terabytes), would display
+ as 0.909 TiB (tebibytes).</p>
