not always connected to a power source.

connect to the internet without the hassle of wires. It is built
in to most laptops.

dongle will be needed. Bluetooth is used to transfer and
receive files without any cables. This works by special radio
frequencies that transmit from one device to another.

built in speakers in the laptop, which produces enough sound.
But however if more sound wants to be produced there are
speakers which are specialist for laptops.
