Question
Which type of protocol is used in Ethernet to avoid all machines transmitting at the same time?
Solution 1
The protocol used in Ethernet to avoid all machines transmitting at the same time is called CSMA/CD (Carrier Sense Multiple Access with Collision Detection). Here's a step-by-step explanation of how it works:
-
When a device has data to send, it first checks the network to see if it's busy. This is the "Carrier Sense" part of CSMA/CD.
-
If the network is not busy, the device begins transmitting data.
-
While transmitting, the device continues to listen to the network to see if a collision
Solution 2
The protocol used in Ethernet to avoid all machines transmitting at the same time is called CSMA/CD (Carrier Sense Multiple Access with Collision Detection). Here's a step-by-step explanation of how it works:
-
When a device has data to send, it first checks the network to see if it is free for transmission. This is the "Carrier Sense" part of CSMA/CD.
-
If the network is free, the device begins transmitting the data. If the network is not free, the device waits and checks again later.
-
While transmitting, the device continues to listen to the network to make sure no other devices start transmitting. This is the "Multiple Access" part of CSMA/CD.
-
If another device starts transmitting and a collision occurs, both devices stop, wait for a random amount of time, and then start the process over. This is the "Collision Detection" part of CSMA/CD.
-
This process continues until the device is able to transmit its data without a collision occurring.
This protocol ensures that all devices get a fair chance to transmit their data and helps to minimize data loss due to collisions.

Ethernet is the most commonly used Link Layer protocol in use today. Like all link layer protocols, it enables direct communication between any two nodes on the local network (a.k.a. LAN). Since it is focused on point-to-point communications it is extremely difficult (almost impossible) to eavesdrop on Ethernet communication.Group of answer choicesMostly True - some flavors of Ethernet are susceptible to eavesdropping but even these require large, expensive equipment to compromise.Mostly false - all flavors of Ethernet are susceptible to eavesdropping, however since the packets are only on the local LAN you need to have physical access to the local LAN. So you can't eavesdrop on Ethernet from remote locations without breaking into a computer attached to the LAN you want to listen to.Mostly false - all flavors of Ethernet are susceptible to eavesdropping, and since Ethernet is used everywhere this means anyone, anywhere can listen in on traffic from any computer in the world.
