Buffer overflow is like a digital smoothie disaster, when your data blender overflows and creates a cyber mess. This occurs when too much information is crammed into a limited space, causing it to spill out and potentially lead to system crashes or security breaches. It’s like a digital suitcase crammed with too many clothes, where a program or app tries to stuff excess data into a temporary storage spot (the buffer). That extra info spills into other parts of the computer’s memory when it overflows. Crafty hackers love exploiting this chaos, leading to unauthorized code running or system crashes. You can prevent these digital smoothie spills by keeping your software up-to-date and applying security patches.
