What is single step debugging?
Single Step debugging of machine instructions is a technique often used during vulnerability research and exploit development to debug a program at an atomic level.
What do you mean by single stepping in a debugging environment?
Single-stepping is one of the most powerful features of a debugger, as it allows a reverse engineer to execute a single instruction at a time before returning control to the debugger.

What is stepping in programming?
In a suspended program, you get control over the program execution. By stepping through the program, you can advance the execution point to the code you are interested in and examine the program state at this point.
What is a breakpoint in coding?
A breakpoint is a point in the program where the code will stop executing. For example, if the programmer amended the logic error in the trace table example they may wish to trigger a break point at line 5 in the algorithm.
How does GDB single step?
To execute one line of code, type “step” or “s”. If the line to be executed is a function call, gdb will step into that function and start executing its code one line at a time. If you want to execute the entire function with one keypress, type “next” or “n”.

How do breakpoints debug a program?
A break point is a mark in your code where the debugger should stop so you can check values of variables and the general state of program’s execution.
How do software breakpoints work?
Software breakpoints put an instruction in RAM that is executed like a TRAP when your program reaches that address. While hardware breakpoints use a register of the CPU to implement the breakpoint itself. That is why the hardware breakpoints are much faster.
How does a software breakpoint work?
Software Breakpoint They work by patching the code you are trying to execute with an instruction that triggers a debug event in some fashion. This is accomplished by injecting a breakpoint instruction or when that is not supported by inserting an instruction that causes a fault that halts the core.
