Your keyboard can start to smell and typing can be sticky. This can attract bugs which makes ur life unpleasant etc. If your mouse is dirty, I don't think anything bad might happen.

Output, Because they dont affect the computer, but a keyboard is input because you can enter keystrokes. Same for a mouse.
I would go into your start up menu and check if your PC has the USB connection checked.Also check if the mouse and keyboard work on other computers.if they work than its your computer if they dont work check for wear and tear on the mouse and keyboard cables and connector ends.
If you keyboard is unable to pick up its signal, trying unplugging it off and replugging it.

To calibrate your mouse, you can adjust the pointer speed, enhance precision by fine-tuning sensitivity settings in the mouse control panel, and use a mouse pad for smoother movement. You can also update mouse drivers and firmware for optimal performance.
