Ethernet is a technology that is used on local area networks; it is now known as an industry standard. Therefore, Ethernet is a LAN technology. Ethernet was not widely used within home computing; until the "boom" in Internet usage, and the requirement within domestic homes for multiple devices to be connected to the Internet. Through the use of the home router - which is a descendant of the IMPs that were first designed for ARPANET - multiple wired and wireless devices can use the same Internet connection. Most modern routers feature 4 Ethernet ports; for wired connections. It is also a rarity for a home computer not to feature an Ethernet port.
Before the expansion of Internet usage and broadband, Ethernet was rarely implemented into dialup modems. It was only when broadband infrastructure was built, that homes began to require multiple connections; a router basically functions as a domestic LAN (Local Area Network). Ethernet has evolved over the years; since it's development and introduction in 1980. The technology has evolved so that it can handle transporting more data. Ethernet can transmit data that is broken down into packets; with each packet transmitted using the CSMA/CD algorithm; until it arrives at the destination without colliding with any other packet. Ethernet can also specify the collision detection of the transceiver; so that it must be activated during the inter-packet gap.
