Briefly describe both the similarities and differences between a wired Ethernet NIC and a wireless Ethernet NIC.
What will be an ideal response?
A wired Ethernet NIC and a wireless Ethernet NIC are alike in that they take data passed down from the upper OSI layers, encapsulate it into data packets, send the packets out on the network media as binary data, and receive data packets sent from other NICs. The main difference is that rather than charging up a network cable with electrical current, as an Ethernet NIC for copper cabling would do, or sending out light pulses, as an Ethernet NIC for fiber optic would, a wireless NIC transmits and receives radio waves.
