What are breakpoints in an IDE?

What is the difference between a hardware breakpoint and a software breakpoint?

Hardware breakpoints are the fastest and the most used breakpoint. Hardware breakpoints have a problem. A software breakpoint is typically an instruction that temporarily replaces an instruction in RAM that is either an illegal instruction and causes a fault or is designed to cause the application to break.

What happens when a program hits a software breakpoint?

When a breakpoint is hit, for both software and hardware breakpoints, a debug interrupt is generated and the debugger stops at the breakpoint address. For the software breakpoints, the debugger modifies the program code.
