let's say they catch-up to each other after t hour.

so

in t hour distance travelled by Renee

d = speed × time = 50t

in t hour distance travelled by Kim

d = speed × time = 60(t-1) + 0×1 = 60(t-1)

Note: here kim didn't covered any distance in first hour and in rest t-1 hour it travelled all distance

now.as distance travelled by both is same so

60(t-1) = 50t

60t -60 = 50t

adding 60 both sides

60t = 50t+60

subtracting 50t both sides

60t -50t = 50t+60 - 50t

10t = 60

dividing by 10 both sides

t = 60/10 = 6

so in 6 hour both will catch-up to each other

Three PCs are on an Ethernet LAN, connected by a hub. Describe how the Ethernet protocol deals with collisions in this situation
sdas [7]

Answer:

All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.

A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision

Explanation:

Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.

CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.
