Keyboard
It is an input device used to type words or numbers on the monitor or to control things like video games with the arrow keys.
Mouse

Ethernet/RJ45 Port
Port that allows you to have a hard-wired connection to the internet
USB A port
a data and power connection where you plug in things like keyboards, mice, video game controllers, smartphones, tablets or fancy headphones and speakers. Many "smart" devices use this type of connection because you can charge and sync through one cable.
USB B port
