Connecting the Ethernet Adapter to Your Network
There are two network scenarios as below:
Ad-hoc
Networking
Also known as a peer-to-peer network, an ad-hoc network is
one that allows all workstations and computers in the network
to act as servers to all other users on the network.
Users on the network can share files, print to a shared printer,
and access the Internet with a shared modem. However, with
ad-hoc networking, users can only communicate with other
wireless LAN computers that are in the same wireless LAN
workgroup, and are within range.
<PC to Network Printer>
<PC to PC >
Infrastructure
Networking
Infrastructure networking differs from ad-hoc networking in
that it includes an access point. Unlike the ad-hoc structure
where users on the LAN contend the shared bandwidth, on
an infrastructure network, the access point can manage the
bandwidth to maximize bandwidth utilization.
Additionally, the access point enables users on a wireless
LAN to access an existing wired network, allowing wireless
users to take advantage of the wired networks resources,
such as Internet, email, file transfer, and printer sharing.
Infrastructure networking has the following advantages over
ad-hoc networking:
Extended range: each wireless LAN computer within the
range of the access point can communicate with other
wireless LAN computers within range of the access point.
