Notes The ‘New Network Link’ dialog box appears. Enter the name of your link in the ‘Name’
field. Enter the full path of the KMZ file in the ‘Link’ field, or browse to the file location if
the file is located on a network. You can use a URL to reference the KMZ, such as ‘http://
www.test.com/myKMZ.kmz’. The 3D viewer immediately flies to the default view for the
linked data.
2. Enter descriptive text or HTML.You can enter this data in the same way you would for a
regular folder. See Editing Places and Folders for more information.
3. (Optional) Click the View tab to change the default view that this network link presents
to users. Click Snapshot current view to use your current view in Google Earth. If your
network link has more than one placemark, click Reset to display all these placemarks to
users.

The text you enter in this description is your description of the link only and
is not viewable by anyone else linking to the KMZ file. Only you will be able
to see the description you enter here (unless you email your link folder to
other people). This is similar to creating a bookmark for a web page and then
adding a descriptive note about the bookmark.
4.2 Use of a Network

Connecting computers in a local area network lets people increase their efficiency by sharing files,
resources, and more. Local area networking has attained much popularity in recent years—so
much that it seems networking was just invented. In reality, local area networks (LANs) appeared
more than ten years ago, when the arrival of the microcomputer gave multiple users access to
the same computer.
(a) These are three of the most common benefits of using a LAN.
(b) Increased efficiency
(c) Improved communications

4.3 Types of Networks

A network can be classified in following ways:
4.3.1 Based on Server Division

4.3.1.1 Peer-to-Peer Networking

This is a simple network configuration that requires some basic know-how to set up. Each of the
interconnected machines share dual capability and responsibility on the network. That is to say,
that each machine serves a dual purpose or role, i.e. they are both clients and servers to some extent.
The server capability of the machines is very basic. The services provided by each, is no more
than the ability to share resources like files, folders, disk drives and printers. They even have the
ability to share Internet access.
However, the server functionality of these machines stops there. They cannot grant any of the
benefits mentioned previously, since these are functions provided only by a dedicated server
operating system.
Because all machines on the network have equal status, hence the term peers, there is no centralised
control over shared resources. Sharing is endorsed or repealed by each machine’s user. Passwords
can be assigned to each individual shared resource whether it is a file, folder, drive or peripheral,
again done by the user.
