Ethernet - World of Networking

The most widely used local area network (LAN) technology. Defined as the 802.3 standard by the IEEE, the Ethernet access method is used to connect computers in a company or home network as well as to connect a single computer to a modem for Internet access.

A 10/100 Ethernet port transmits 10 and 100 Mbps, while the maximum speed of a 10/100/1000 "Gigabit" port is 1 Gbps. Ethernet uses the highest common speed between sending and receiving devices.
TOPOLOGY OF ETHERNET
Star Network 
Each network host is connected to a central hub with a point-to-point connection
Ring Network
 A  bus topology in a closed loop. Data travels around the ring in one direction. When one node sends data to another, the data passes through each intermediate node on the ring until it reaches its destination
Bus Network 
Each node is connected to a single cable, by the help of interface connectors. This central cable is the backbone of the network 
Mesh Network  
The value of fully meshed networks is proportional to the exponent of the number of subscribers, assuming that communicating groups of any two endpoints, up to and including all the endpoints
