In this case, the adapter extracts the payload data from the incoming Ethernet frames.

With incoming data, an Ethernet network adapter again works with driver and networking software. The CRC Checksum is used to ensure the data has not been corrupted in the transmission. The last element of the Ethernet frame is a small amount of data called a CRC Checksum. The destination information is used by networking equipment to direct the packet to recipient's computer.Ī second part of the Ethernet frame is the payload, which is essentially the small chunk of raw data. Each Ethernet frame has a header with information about the destination and source address. It then places these small chunks of data into packets, called Ethernet frames. For outgoing data, the adapter parses large blocks or streams of data into small chunks. To send and receive data, an Ethernet network adapter works in conjunction with networking and driver software. Fiber optic adapters are also used when the computer is very far away from the hub or switch. For example, a fiber optic adapter would be used when a cable passes an area where there is lots of electrical interference.
The cable may be made of copper wires or fiber optic cables typically, fiber optic Ethernet network adapters are only used in special cases. The cable connects a computer to networking hub, switch, or router. Every Ethernet network adapter has a jack that accepts a cable, which carries the data.
