the author said
"#define DEF_COUNTER ( 10 * HZ / 100)
Since HZ (which denotes the frequency of timer interrupts) is set to 100 for IBM compatible PCs (see
Section 6.1.3), the value of DEF_COUNTER is 10 ticks¡ªthat is, about 105 ms."
why does the value is 105 ms instead of 100ms ?
Thank in advance for anyone's help.
