Answer #1

Intelx86 debugger implements a software break point by modifying the memory in the RAM where the opcode is stored.For example where the break point is put there the opcode is replaced with a special instruction to enter the system into debug mode in a forced manner.

It might be better to use a hardware break point over a software break point is that hardware break point is faster compared to the software break point as it has got dedicated registers and does not concentrate on modifying memory.
