For example, the signing application may require all requests to come from digitally signed binaries.
2.
XOR is also used to detect an overflow in the result of a signed binary arithmetic operation.
3.
This is because a positive value of 128 cannot be represented with an 8-bit signed binary numeral.
4.
As PLCs typically use 16-bit signed binary processors, the integer values are limited between-32, 768 and + 32, 767.

:: As far as I know, not only there is no Linux for the Razr, but also the bootloader ( which probably is in a builtin ROM ) only accepts signed binaries ( IIRC, I saw this info on some site which had the layout of the Razr flash files, a long time ago ).
