Collision
Collision : two or more devices on a network try to
send data at the same time, those data packets
colliding with each other.
Collision
Network
When a collision occurs, communication speed
down because of waiting time and retransmission
One of the solution for too much collisions is
reducing the number of devices in a network 8

Summary
Do you know the differences about Hub, Switch, Router?
[Hub]
A hub is the least complex and least expensive device.
[Switch]
The switch controls a data packet. As a result, a switch can greatly
improve the speed of networks that have a lot of traffic.
[Router]
The router can not only forward data packets to other devices in a
single network, but also forward data packets between two or more
networks.
