Wired Home Networks
Home networks: Provide users with the ability to share
files and other resources Can be configured as either wired or
wireless Utilize the Ethernet communications
standard to stipulate how data is transmitted

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

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.

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.
