Explanation:
A Star network is the most common network in use today. Ethernet networks with computers connected to a
The switch forms the central component of the star. All network devices connect to the switch. A network switch
When the switch receives data on one of its ports from a computer, it looks in the MAC address table to
The switch that forms the central component of a star network is a single point of failure. If the switch fails, no
