example, within an office building or home) that share a
common communications line and resources. When you set
up a network, you can share files, peripheral devices (such
as a printer) and an internet connection. You can set up a
LAN using wired technologies (such as Ethernet) or wireless
technologies (such as Wi-Fi or Bluetooth).

which may link two or more computers without using wires.
Setting up a wireless network is easy and allows you to
share files, peripheral devices and an internet connection.
