The most popular networking standard at the moment is Ethernet which one can recognize by the rectangular connectors with eight wires in them. Wireless network with the 802.11b and the faster 802.11g standard is also increasingly popular both at home and in the office though it is not yet as fast as wired ethernet network. A public place where you can use wireless internet is called a hot spot.
