Idiot-proof

Idiot-proof means making something simple and easy to use so that even if someone who doesn't know much can use it. For example, when toys are made, the manufacturer designs the toy in a way so that kids can easily play with it without getting hurt. Similarly, when we make software, we try to make it easy for everyone to use, even those who might not be very good at using computers. This includes little things like big buttons and clear instructions, so that everyone can understand and use it without any problems. It's like building a puzzle with big pieces that fit together easily, so that every kid can complete it without any difficulty.
