A local reboot is like taking a nap for your computer. When you use your computer for a long time, it can get tired and slow down. Just like you need to rest to feel refreshed and energetic, your computer needs to rest too.
When you give your computer a local reboot, it means you turn it off and turn it back on again after a short break. This helps your computer clear out any problems or issues it might be experiencing and start fresh.
Think of it like when you're building with blocks and you accidentally knock over your tower. You can either keep trying to fix the toppled blocks or you can start from scratch and build a new tower. The same goes for your computer: a local reboot lets it start fresh, like building a new tower of blocks.
This process is also helpful when your computer starts acting weird or glitchy. Just like when you get sleepy or hungry and start acting grumpy, your computer can act weird if it needs a break. Giving your computer a local reboot can help it feel better and work more smoothly.
