Why this chapter

The Internet and networking is an important part of using the computer. To connect the
computer to a network or the Internet, using wired or wireless connection, you need to set
up a connection and also be able to manage it. In Windows XP, the Network and Internet
Connections option allows you to do that. The purpose of this chapter is to introduce you
to the Network and Internet connections of Windows XP.

​ INTRODUCTION

3
Windows XP provides many ways using which to network or link computers at home, at office or to the
Internet. Windows XP provides easy-to-follow wizards to help create, manage, and secure your network.
You can set up five types of network connections i.e., dial-up connections, local area connections, virtual
private network connections, direct connections using serial or parallel cables, and call in to a remote
access server from your home or office. It is also possible to set up wired connections or wireless
connections to connect to other computers or the Internet. Windows XP also allows setting up a Firewall
that blocks access to the computer from the Internet or a network program and service that is not trusted.

In this chapter, we describe the Network and Internet Connections of Windows XP. The chapter
describes creating and managing the network connections, setting up a wired and wireless connection,
setting up the Firewall, and making Internet settings using the Internet options.

​ START NETWORK CONNECTIONS

The network connections setting in Windows XP specifies how to connect the computer to a network. It
might also be needed to change the network settings if the Internet Service Provider (ISP) is changed.

The steps to start the network connections is as follows:

1. <Start> <Control Panel> <Pick a Category> <Network and Internet Connections> <or pick
a Control Panel icon> <Network Connections> (Figure 20.1)
2. Windows XP displays the Network Connections window.

All the network connections (Figure 20.2) of the computer can be seen

​ CREATE A NEW CONNECTION

To create a new connection, the New Connection Wizard has to be started. The new connection wizard
helps to create a connection to the Internet, to another computer, or to the workplace network. The New
Connection Wizard supports setting up the different types of network connections like broadband,
Virtual Private Network (VPN), modem dialup, serial port, parallel port and infrared. The New
Connection Wizard allows the following:

5
 ● Set up a computer to connect to the Internet using a dial-up modem, a cable or DSL modem,or
LAN connection. The Internet Service Provider (ISP) would have provided the settings to be
included on the computer.
● Connect the computer to a private network, such as the company network, using dial-up or VPN
connection to work from home or another location. Your company/organization must give the
access right for the VPN.
● Connect the computer to an existing home or small office network or set up a new one. Assign
a unique name for your computer and type in the workgroup name correctly.
● Set up a Direct Cable Connection (DCC) between two computers using serial, parallel, or
infrared ports.
● Set up your computer for incoming connection that allows other computers on the
local network or on the Internet to connect to it.

To start the New Connection Wizard, do the following steps:

● <Start> <Control Panel> <Network and Internet Connections> <Network Connections>.

A window opens.
● On the left side of window, on the tab Network Tasks, click <Create a new connection> (Figure
20.3)
● A New Connection Wizard opens. Click Next to continue.
● Select Network connection type. The Network Connection Type (Figure 20.4) presents three
choices for Internet and private network setup:

an account with an ISP, then making the Internet connection through that new account.
o Set up my connection manually option sets up connections for accounts that
have already been opened with an ISP (username and password are ready for
use).
▪ Connect using a dial-up modem option works for phone line Internet services.

▪ Connect using a broadband connection that requires a username and password

(DSL or cable modem Internet services).
▪ Connect using a broadband connection that is always on (for “always on” DSL or
cable modem services)
o The CD I got from an ISP option is used when an installation CD-ROM has been given to
you by the ISP.
o Select Choose from a list of Internet Service Providers
● Click Finish.

The Windows XP network connection wizard closes and a new window (Figure 20.6) opens.

Explorer to sign up for InternetAccess (US only) launches the MSN window.

​ MANAGE A NETWORK CONNECTION

Several network management tasks can be performed on a network connection. To manage a network
connection, do as follows:

● Click on the connection you want to manage. Network management task can be performed
on this connection in two ways:
1. On the left side, Network Tasks shows the list of possible tasks you can perform for this
connection, or
2. Right-click on the network connection you want to manage. A pop-up window appears
(Figure 20.7). Select the task to be performed.

Some of the network management tasks you can perform on the selected network connection are as
follows:

● Disable a network connection—Right-click. <Disable>.

● Enable a network connection—Right-click. <Enable>.

​ NETWORK SETUP

The Network Setup wizard is used after physically connecting all computers in the network with the
necessary hardware. The Network Setup Wizard helps do the following:

● Configure all computers in the network to share one Internet connection through a
hub, gateway etc.
● Set up Windows Firewall to protect the computer or network when it is connected to
the Internet.
● Enable file and printer sharing so that certain files, folders, or printers can be accessed by all
computers in the network.

Network Setup Wizard can be used as follows:

● <Start> <Control Panel> <Network and Internet Connections> <Network Setup Wizard> (Figure
20.9).
● Click Next. On each window that opens follow the instructions and then click on Next. Finally
you will reach the window showing Finish. Click on Finish to complete the setup.

Figure 20.9 Network setup wizard

​ WINDOWS FIREWALL

Windows firewall is a protective boundary that monitors the incoming traffic from the network and
Internet. Using the firewall, guards against the intruders and unauthorized persons over the

11
network and the Internet. When connected to the Internet or a network, it blocks unauthorized access to
the computer. However, the programs and services that you trust can access your computer. Windows
Firewall does not provide the options to filter outgoing connections.

The Windows Firewall is turned on by default. In Windows XP, Windows Firewall is part of the Windows
Security Center. Windows Security Center manages the security settings of Internet Options, Windows
Automatic Updates and Windows Firewall. It constantly checks whether Windows Firewall is on, and
displays an alert message if it is turned off. Windows Security Center also monitors the antivirus software
to ensure that it is updated.

The Windows Firewall window can be opened in either of the following ways:

● <Start> <Control Panel> <Network and Internet Connections> <Windows Firewall>, or

● <Start> <Control Panel> <Network and Internet Connections> <Change Windows Firewall
settings>, or
● <Start> <Control Panel> <Security Center> <Windows Firewall>, or
● <Start> <Control Panel> <Windows Firewall>, or
● <Start> <Connect To> <Show all connections> <Network Tasks> <Change Windows Firewall
settings>, or
● <Start> <All Programs> <Accessories> <Communications> <Network Connections> <Network
Tasks> <Change Windows Firewall settings>, or
● <My Network Places> <View network connections> <Network Tasks> <Change Windows Firewall
settings>.

The Windows Firewall is opened as follows:

● <Start> <Control Panel> <Network and Internet Connections> <Windows Firewall>.

● Windows Firewall window opens (Figure 20.10). It has three tabs—General, Exceptions and
Advanced. You can make the Firewall settings from here.

12
Figure 20.10 Windows firewall

​ SHARING OF FILES

Windows XP allows the local sharing and network sharing of the files and folders. To share a file or
folder with other users, perform the following steps:

● Right-click on the folder name you want to share.

● Click <Properties>.
● Click <Sharing>.
● Click on Shared Documents for the local sharing (Figure 20.11). Click on Network Setup Wizard
for the network sharing of the file or folder.

13
Figure 20.11 Sharing of files and folders

Sharing rights for the users can also be set. Permissions can be allowed or denied to specific users or
groups for the sharing of the folder. To share the individual files, put the files in the same shared
folder. All the files and folders in the parent shared folder will be automatically shared.

​ WIRELESS NETWORK SETUP

The Wireless Network Setup Wizard enables creation of a secure wireless network. Choose the security
scheme to be Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA). WPA gives stronger
security to your network, but make sure that the hardware (network adapter and access point) supports
WPA.

The Wireless Network Setup Wizard can be started as follows:

14
<Start> <Control Panel> <Network and Internet Connections> <Wireless Network Setup Wizard> The
Wireless Network Setup Wizard (Figure 20.12) helps to:

Figure 20.12 Wireless network setup wizard

● Create a wireless network in which a wireless access point connects all computers together. It is
necessary to assign a network name—Service Set Identifier (SSID) and a secure key with either
WEP or WPA encryption (Figure 20.13). An SSID is the name of a wireless local area network
(WLAN). All wireless devices on a WLAN must use the same SSID to communicate with each
other. The SSID on wireless clients can be set either manually, by entering the SSID into the client
network settings, or automatically by leaving the SSID blank. You can save your network settings
to a Universal Serial Bus (USB) flash drive and use it for configuring the wireless access point and
other computers. The USB flash drive can only be used for setting up wireless LAN devices (e.g.
access point, camera and phone) that support Windows Connect Now technology (WCN). There
is an option to print the network settings and set up the network manually.

15
 Figure 20.13 To enter a WEP key for wireless network

● Add a computer to an existing wireless network. You can use the USB flash drive to which
settings were saved during your wireless network creation, or you can set up the network
manually. To use the flash drive, just plug in the USB flash drive to each computer that you want
to add to the existing wireless network and confirm that the computer will be added to the
existing wireless network when prompted by the wizard. Then the computer will be configured
automatically for joining the existing wireless network.

​ CONNECT USING VIRTUAL PRIVATE NETWORK (VPN)

A VPN provides remote users with secure access to the organization’s network via public infrastructure
such as the Internet. To connect to the VPN, first make the settings required to make the connection, as
follows:

● <Start> <Control Panel> <Network and Internet Connections> <Network connection> <Create a
new connection>. The New Connection Wizard appears. Click Next.
● Select Connect to the network at my workplace. Click Next.
● Select Virtual Private Network connection. Click Next.
● In the Company Name text box, type the name given by your company for the connection. Click
Next,
● In the Host name or IP address text box, type the hostname of our company’s computer to
which you want to connect to. Click Next.
● Select My use on. Click Next.
● Check the checkbox for Add a shortcut to this connection to my desktop. Click Finish
● Click Cancel to exit.

16
To connect to the VPN, do as follows:

● From the Desktop, double click your VPN connection shortcut.

● A dialog box appears. Enter your user name and password.
● Click Connect.

​ SET UP A WIRED NETWORK

Wired networks offer good performance, reliability and security. Wired networks are used to connect
your desktop computer to the Internet and to other computers in your home. If you have a single
computer, connecting to the Internet requires plugging a network cable into the computer and the
modem. If there is more than one computer, connect a router between your modem and your computers.
If the computer is in a different room from that of the router, a network extender can be used to connect
the computer.

The steps to connect the computer to the Internet connection using a wired network are as follows:

● Use the services of an Internet service provider (ISP) to have them configure an Internet
connection to your home. Preferably, place the modem in the room with your computer.
● Your computer must have a Network adapter.
● Shut down your computer. <Start> <Turn off Computer> <Turn Off>.
● Connect the network cable given to you by your ISP to your network adapter. Connect the other
end of the network cable to your modem.
● Start your computer and log on to Microsoft Windows.
● Windows automatically detects that you are connected to the Internet.

Your wired connection to the Internet is now ready for use.

​ AUTOMATIC WIRELESS NETWORK CONNECTIONS

Windows XP allows establishing a wireless network connection to Wi-Fi network routers and access
points automatically. This feature helps to make wireless Internet or Wi-Fi network connections easily
with laptop computers. The steps to be followed to establish a wireless network connection automatically
are as follows:

● Check whether the Windows XP computer supports automatic wireless configuration. For
this do as follows:
o <Start> <Control Panel> <Network and Internet Connections> <Network Connections>
o Right-click <Wireless Network Connection> <Properties>

In the Wireless Network Connection properties window, if you see a Wireless Networks tab, then you can
automatically connect to wireless network connections. Click it.

● To enable automatic configuration, Use Windows to configure my wireless network settings

checkbox must be checked on the Wireless Networks tab of the Wireless Network Connection

17
 properties window (Figure 20.14). Automatic wireless network configuration will be disabled if
this checkbox is unchecked.

Figure 20.14 Use Windows to configure wireless network

● The Wireless Networks tab allows access to the set of Available networks (Figure 20.15).
Available networks represent the active networks currently detected by Windows XP. To view
the available networks, click the View Wireless Networks button on that page.

Figure 20.15 View wireless networks

● You can also build a set of “Preferred networks” (Figure 20.16) when automatic wireless
configuration is active. This list represents a set of known Wi-Fi routers or access points you
wish to automatically connect to in future. The order Preferred networks are listed here
determines the order that Windows XP will automatically attempt when seeking to make a
wireless connection. You can set this order to your preference.
● By default, Windows XP enables automatic wireless configuration support. Also, by default,
Windows XP only auto-connects to Preferred networks.
● The Advanced button on the Wireless Networks tab of Wireless Network Connection properties
controls the default behavior of Windows XP automatic connections. The Automatically connect
to non-preferred networks, allows Windows XP to auto-connect to any network on the Available
list, not just Preferred ones. This option is disabled by default.
● When the View Wireless Networks button on the Wireless Network tab is clicked, all the
available wireless networks in range (Figure 20.17) are seen. Choose the network that you wish
to connect to and click the Connect button.

18
 Figure 20.16 Preferred networks

Figure 20.17 Choose a wireless network

● If the wireless network is protected, click Change advanced settings. A Wireless Network
Properties window opens. Click on the Wireless Networks tab. In the Preferred network, select
the network you want to connect to. Click <Properties>. A window opens. It has three tabs—

19
 Association, Authentication and Connection. Make the required entries in these tabs. Click
<OK>.
● You should now be connected to the wireless network.

​ SET UP INTERNET PROPERTIES—INTERNET OPTIONS

Once you are connected to the Internet, you need to use the Web Browser to access the World Wide
Web (WWW). The Internet Explorer is a Web browser software that comes bundled with the Windows
software. The Internet can be accessed by clicking on the Internet Explorer icon jjA. The Internet
Explorer settings can be modified using the Internet Options. Internet Options allows you to change the
settings of Internet Explorer, but it cannot be used to change the settings of other Web browsers.

To Open Internet Options, do as follows:

● <Start> <Control Panel> <Network and Internet Connections> <Internet Options>.

● An Internet Properties window opens.

The Internet Properties window (Figure 20.18) has seven tabs—General, Security, Privacy, Content,
Connections, Programs and Advanced. Specify the first Web page you see on starting the browser, delete
temporary Internet files stored on the computer, use Content Advisor to block access to objectionable
material, and specify how colors and fonts are displayed on Web pages.
You can also set the security level and specify which programs to use for email. In short, you can make
all the settings for the Internet browser from here.

20
Figure 20.18 Internet properties

​ CHOOSE AN INTERNET CONNECTION

With the growth of technology, the content on the Web has also changed. Now web applications include
content like animations, online gaming, database-driven Web sites and e-commerce.
Thus, the need for speed as to how fast we can connect to the Internet has changed.

The overall connection speeds of the different types of Internet connections are given below. There can be
variations amongst different Internet Service Providers (ISP).

● Dial-up access is economical but slow. Dial-up access uses normal telephone lines so the
quality of the connection is not always good. Speed is 2400 bps to 56 Kbps.
● Integrated Services Digital Network (ISDN) is an international communications standard for
sending voice, video, and data over telephone lines. Speed is 64 Kbps to 128 Kbps.
● DSL is an always on connection. ADSL is the most commonly deployed type ofDSL. Speed is
128 Kbps to 8 Mbps.
● Cable modem gives you a broadband Internet connection that is designed to operate over cable
TV lines. Speed 512 Kbps to 20 Mbps.

21
 ● Wireless Internet Connections uses radio frequency bands. Wireless Internet provides an always-
on connection which can be accessed from anywhere geographically within a network coverage
area. Their speed varies.
● T-1 Lines are a leased line option for businesses connecting. T-1 Lines support speeds of 1.544
Mbps.
● Internet over Satellite (IoS) allows a user to access the Internet via a satellite that orbits the
earth. Speed: 492 Kbps to 512 Kbps.

For home users, the ADSL connection is the best suited. It is a broadband connection, always on, not very
expensive and can be used with the telephone line. It has a fairly good speed also. You can also connect
your broadband connection to a wireless modem internally in the home, to access the Internet connection
from any room of the house wirelessly.

Introduction to email

Do you ever feel like the only person who doesn't use email? You don't have to feel left out. If you're just getting started,
you'll see that with a little bit of practice, email is easy to understand and use.

In this lesson, you will learn what email is, how it compares to traditional mail, and how email addresses are written.
We'll also discuss various types of email providers and the features and tools they include with an email account.

Getting to know email

Email (electronic mail) is a way to send and receive messages across the Internet. It's similar to
traditional mail, but it also has some key differences. To get a better idea of what email is all about, take a
look at the infographic below and consider how you might benefit from it’s use

22
23
 Email advantages

● Productivity tools: Email is usually packaged with a calendar, address book, instant messaging, and more for
convenience and productivity.
● Access to web services: If you want to sign up for an account like Facebook or order products from services like
Amazon, you will need an email address so you can be safely identified and contacted.
● Easy mail management: Email service providers have tools that allow you to file, label, prioritize, find, group,
and filter your emails for easy management. You can even easily control spam, or junk email.
● Privacy: Your email is delivered to your own personal and private account with a password required to access
and view emails.
● Communication with multiple people: You can send an email to multiple people at once, giving you the option
to include as few as or as many people as you want in a conversation.
● Accessible anywhere at any time: You don’t have to be at home to get your mail. You can access it from any
computer or mobile device that has an Internet connection.

Understanding email addresses

To receive emails, you will need an email account and an email address. Also, if you want to send emails to other
people, you will need to obtain their email addresses. It's important to learn how to write email addresses correctly
because if you do not enter them exactly right, your emails will not be delivered or might be delivered to the wrong
person.

Email addresses are always written in a standard format that includes a username, the @ (at) symbol, and the email
provider's domain.

The username is the name you choose to identify yourself.

The email provider is the website that hosts your email account.

Some businesses and organizations use email addresses with their own website domain.

24
 About email providers

In the past, people usually received an email account from the same companies that provided their Internet access. For
example, if AOL provided your Internet connection, you'd have an AOL email address. While this is still true for some
people, today it's increasingly common to use a free web-based email service, also known as webmail. Anyone can use
these services, no matter who provides their Internet access.

Webmail providers

Popular webmail providers are Yahoo!, Microsoft's Outlook.com (previously Hotmail), and Google's Gmail. These
providers are popular because they allow you to access your email account from anywhere with an Internet connection.
You can also access webmail on your mobile device.

Visit the links below to compare the features of the three top webmail providers:

● Yahoo! Features
● Outlook.com Features
● Gmail Features

Other email providers and applications

Many people also have an email address hosted by their company, school, or organization. These email addresses are
usually for professional purposes. For example, the people who work for this website have email addresses that end with

25
@gcflearnfree.org. If you are part of an organization that hosts your email, they'll show you how to access it.

Many hosted web domains end with a suffix other than .com. Depending on the organization, your provider's domain
might end with a suffix like .gov (for government websites), .edu (for schools), .mil (for military branches), or .org (for
nonprofit organizations).

Many companies and organizations use an email application, like Microsoft Outlook, for communicating and managing
their email. This software can be used with any email provider but is most commonly used by organizations that host
their own email.

Email productivity features

In addition to email access, webmail providers offer various tools and features. These features are part of a
productivity suite—a set of applications that help you work, communicate, and stay organized. The tools offered will
vary by provider, but all major webmail services offer the following features:

● Instant messaging, or chat, which lets you have text-based conversations with other users...

● An online address book, where you can store contact information for the people you contact frequently...

26
●

27
● An online calendar to help organize your schedule and share it with others...

● A public profile that you can use for basic social networking purposes, like sharing photos, previous work
or school history, and status updates, among other things...

28
In addition, each provider offers some unique features. For instance, when you sign up for Gmail you gain access
to a full range of Google services, including Google Drive, Google Docs, and more. You can visit our tutorials on
Google Drive and Google Docs to learn more.

Getting started with email

You should now have a good understanding of what email is all about. Over the next few lessons, we will continue
to cover essential email basics, etiquette, and safety tips.

Setting up your own email account

If you want to sign up for your own email account, we suggest choosing from one of the three major webmail
providers:

● Yahoo! Mail: Click Create Account

● Outlook.com: Click Sign up
● Gmail: Click Create an account

Practice using an email program

Keep in mind that this tutorial will not show you how to use a specific email account. For that, you will need to
visit our Gmail tutorial. It's a useful course for learning the basics, even if you ultimately end up choosing an
email provider other than Gmail, such as Yahoo! or Outlook.com. There, you will learn how to:

● Sign up for an email account

● Navigate and get to know the email interface
● Compose, manage, and respond to email
