We know that modern Ethernet is full-duplex. At the same time we can send Or receive the signal. Suppose I consider one Lan where multiple hosts are connected by different ports of switch.

Let's take host A host connected switch port N via baseband link. Consider A starts sending signal to switch and at the same time switch also starts sending signal to A.

My question is both host A and switch uses entire bandwidth of that baseband link at the same time or uses portion of the bandwidth of this baseband link?

An Ethernet packet uses the full bandwidth of an Ethernet cable. You can only send one packet at a time, and receive one packet at a time.

  • \$\begingroup\$ when two packets meet at point X ,say in between the link MN then also at that point X also uses full bandwidth ? \$\endgroup\$
