A "Hub".
Serial ports transmit data one bit at a time, which is why they are becoming obsolete.
i dont know im the one asking this question hahahah
binary
A port that handles more than one data bit at a time is a parallel port. The most common example is the printerport (LPT) found on most older computers. The port is designed to transmit and receive 8 bits at a time. Parallel ports are less common on modern computers as the USB port has now replaced it for the majority of applications.
Digital Data is data that is stored in binary, and a Digital Device is any device that works with binary data
modem
Data Transceiver
A router connects multiple computers together and transmits data to its correct destination on a network.
Ethernet is bi-directional; it both transmits and receives data.
The printer is an output device i.e. it transmits data in the form of prints.

Serial ports only allow one device to send and one device to receive at a time, where a parallel port can send and receive data at the same time.
The ICH
Serial ports transmit data one bit at a time, which is why they are becoming obsolete.
A hub is a device that transmits data out all interfaces expect the incoming interface. If you have an incoming frame from fa0/1, that frame will be sent out all other ports on the hub. When those frames reach the NIC of the PC's, they will discard it if it is not destined for their MAC address.
A Bluetooth device produces radio waves, which are a type of electromagnetic wave that transmits data wirelessly between devices within a short range.
