Half

10 Mb/100 Mb

Application Specific Integrated Circuit

Switches are bridging done in a hardware called ASIC. Switches forward information and data directly to a data link address

Hubs send information to everyone connected to it. Switches send information to a specific data link address

A router

It is based on the network address

Layer 3 switches

Wireless Access Point

Power Line Communication

EOP

Ethernet Over Power

500 Mb / s

It is putting power over an ethernet connection

Putting a network connection over a power cable
