Those connectors can be connected a big battery like LiPo one, they don't burn and heat up easily. The usb connector is for me to connect with some flight controllers.
Voltage divider: Just the resistors dividing the voltage. Voltage regulator: provide static output voltage from different input voltage. Voltage follower: give current gain. Voltage convertor: AC to DC or reverse.
TTL devices for logic ICs.
