Answer 1

The correct answer is Jam signal.

Key Points

In CSMA/CD (Carrier Sense Multiple Access with Collision Detection), when a station detects a collision, it stops its transmission immediately and sends a Jam signal to inform other stations about the collision.
This Jam signal ensures that all other stations are aware that the data sent during the collision is corrupted and should be discarded.
After sending the Jam signal, the station waits for a random amount of time before attempting to retransmit the data to avoid further collisions.
This random delay is determined by the exponential backoff algorithm, which helps to minimize the chances of repeated collisions.

Additional Information

CSMA/CD is a network protocol used in Ethernet networks to control access to the shared medium.
The Jam signal is typically 32 bits long and helps to ensure that the collision is detected by all stations in the network.
CSMA/CD is primarily used in half-duplex Ethernet networks, where simultaneous transmission and reception of data are not possible.
In modern full-duplex Ethernet networks, CSMA/CD is not used since the devices can transmit and receive data simultaneously, eliminating collisions.
