What common communication devices are used in homes to connect to the internet and remote networks and what capabilities do these devices provide?

Solution

A communication device is a hardware device capable of transmitting an analog or digital signal over the telephone, other communication wire, or wirelessly. The best example of a communication device is a computer Modem.

other communication devices include:

Hub: They are more like point contact for the wires to built in the physical network. They do not modify the signals. It is a device connecting multiple ethernet devices together so that they can function together. hub performs in half duplex mode, and floods the packet it received through all the interface of the device.
Switch: Switches are the linkage points of an Ethernet network. Just as in hub, devices in switches are connected to them through twisted pair cabling. But the difference shows up in the manner both the devices; hub and a switch treat the data they receive. Switches remember the interface and the IP address of the receiving packed and latter it performs selective flooding based on knowledge it gained earlier.
Bridge: A bridge is a computer networking device that builds the connection with the other bridge networks which use the same protocol.
Router: Router is a network device that works between two networks and also performs network address translation. And as the name states it also performs packet routing based on various algorithms.
Modem: Modem is a device which converts the digital signals of a computer into analog signals and transmit data via phone lines. The ‘modulator-demodulator’ or modem are generally to two type, Internal and External
Network Card: Network cards are electronic devices that connect the computer to the network. It may use Ethernet interface or even WiFi as an interface to communicate. It generally implements the first two layers of the OSI model. They can also manage some important data conversion function.
