For instance, if you pass a 32-bit value to a function expecting a 16-bit value, and the value is in range, the function may never notice the extra bytes.
举例来说，如果您将一个32位的值传递给一个期望16位值的函数，而且所传递的参数值也在正确范围之内，那么这个函数就永远不会注意到多出来的字节。
When you look closer, hard disks actually include a great deal of extra data in between sectors. These extra bytes are used by the disk's firmware to detect and correct errors within each sector.
仔细查看，就会发现硬盘事实上在扇区之间包括大量额外数据，这些额外字节由磁盘固件使用，以检测和纠正每个扇区内的错误。
