Network connections

A LAN (Local Area Network) is a group of computers (for 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).

Wireless networks

A wireless LAN or WLAN is a wireless local area network, 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.

your home.

modem that will allow you access to a high speed DSL internet

connection. The ISP (Internet Service Provider) you have chosen

normally supplies a modem/router with the subscription to their

services. Read carefully the documentation supplied with your Access
