In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport mechanisms.
MAC ETHERNET CONNECTION SEVERAL TRIES FULL
Most twisted pair cables and network interface cards (NICs) support full duplex mode, but some legacy hardware does not support it. This eliminates the possibility of data colliding with each other on the same cable. The connection has separate wires used for both transmitting and receiving. The same connection supports both transmitting and receiving simultaneously. This is similar to how push-to-talk cellular phones or old-fashioned walkie-talkies operate.įull duplex. For example, while a computer is sending data over the connection, it cannot receive data on the same connection. The same connection supports both transmitting and receiving but only one at a time. For example, a computer can send data over a simplex connection but not receive data on the same connection. Data is sent over the connection in one direction only.

The most common modes are half duplex and full duplex, but simplex mode is used in some specialized connections.
