Wired Home Networks Ethernet-connected computers transmit data in small pieces called packets that include: The data being sent The source computer address The destination address Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall5

Wired Home Networks The Ethernet standard dictates: The wiring required The speed of data transmission over the network The wire and transmission speeds Cat-5 with a transmission speed of up to 100 Mbps. Cat-6 with a transmission speed of up to 1,000 Mbps. Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall6

Wired Home Networks Computers on an Ethernet network are linked through a communication device such as a switch or router. A switch permits the transmission of data on a single network. A router permits the transmission of data on multiple networks, including the Internet. Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall7
