How to use Internet Connection Sharing
To use Internet Connection Sharing to share your Internet connection, the host computer must have one network adapter that is configured to connect to the internal network, and one network adapter or modem that is configured to connect to the Internet.

On the host computer
On the host computer, follow these steps to share the Internet connection:

1. Log on to the host computer as Administrator or as Owner.
2. Click Start, and then click Control Panel.
3. Click Network and Internet Connections.
4. Click Network Connections.
5. Right-click the connection that you use to connect to the Internet. For example, if you connect to the Internet by using a modem, right-click the connection that you want under Dial-up.
6. Click Properties.
7. Click the Advanced tab.
8. Under Internet Connection Sharing, select the Allow other network users to connect through this computer's Internet connection check box.
9. If you are sharing a dial-up Internet connection, select the Establish a dial-up connection whenever a computer on my network attempts to access the Internet check box if you want to permit your computer to automatically connect to the Internet.
10. Click OK. You receive the following message:
When Internet Connection Sharing is enabled, your LAN adapter will be set to use IP
address 192.168.0.1. Your computer may lose connectivity with other computers on
your network. If these other computers have static IP addresses, it is a good idea to set them
to obtain their IP addresses automatically. Are you sure you want to enable Internet
Connection Sharing?
11. Click Yes.

The connection to the Internet is shared to other computers on the local area network (LAN). The network adapter that is connected to the LAN is configured with a static IP address of 192.168.0.1 and a subnet mask of 255.255.255.0

On the client computer
To connect to the Internet by using the shared connection, you must confirm the LAN adapter IP configuration, and then configure the client computer. To confirm the LAN adapter IP configuration, follow these steps:

1. Log on to the client computer as Administrator or as Owner.
2. Click Start, and then click Control Panel.
3. Click Network and Internet Connections.
4. Click Network Connections.
5. Right-click Local Area Connection, and then click Properties.
6. Click the General tab, click Internet Protocol (TCP/IP) in the This connection uses the following items list, and then click Properties.
7. In the Internet Protocol (TCP/IP) Properties dialog box, click Obtain an IP address automatically (if it is not already selected), and then click OK.

Note You can also assign a unique static IP address in the range of 192.168.0.2 to 192.168.0.254. For example, you can assign the following static IP address, subnet mask, and default gateway:

IP Address 192.168.0.2
Subnet mask 255.255.255.0
Default gateway 192.168.0.1


8. In the Local Area Connection Properties dialog box, click OK.
9. Quit Control Panel.

To configure the client computer to use the shared Internet connection, follow these steps:

1. Click Start, and then click Control Panel.
2. Click Network and Internet Connections.
3. Click Internet Options.
4. In the Internet Properties dialog box, click the Connections tab.

9. Click Connect using a broadband connection that is always on, and then click Next.
10. On the Completing the New Connection Wizard page, click Finish.
11. Quit Control Panel.

When you now start Microsoft Internet Explorer, the client computer will try to connect to the Internet by using the host computer's shared Internet connection.

Troubleshooting
When you turn on Internet Connection Sharing on the host computer, the host computer's LAN adapter is automatically assigned the IP address of 192.168.0.1. Therefore, one of the following situations may occur:

* IP address conflict
Each computer on the LAN must have a unique IP address. If more than one computer has the same IP address, an IP conflict occurs, and one of the network adapters turns off until the conflict is resolved. To resolve this conflict, configure the client computer to automatically obtain an IP address, or assign it a unique IP address.
* Loss of network connectivity
If your network is configured with a different IP address range than Internet Connection Sharing uses, you will lose network connectivity with the host computer. To resolve this issue, configure the client computers to automatically obtain an IP address, or assign each client computer a unique IP address in the range of 192.168.0.2 to 192.168.0.254.

Internet Connections

over the years. Internet users have noticed great changes in the type of content accessible on the web due in large part to High Speed Internet Connections another name for Broadband. Remember the fax type of noise every time we wanted to connect via a modem, crossing our fingers we'd be able to on the first try. And when we did get online it was anything but the information super highway we surf today. Pictures were slow to load and drained bandwidth Hmmm Sounds like videos today. Take note google : You might be losing a ton of money on youtube (to be taken literally :) but the lessons of the past prove that technology becomes more efficient and cheaper with time. We now have numerous choices of Internet Connections such as DSL, Cable Internet, Wireless connections, T1, T3, and Satellite Internet Connections to name a few that are faster than anything most of us could have envisioned.

Internet Connections explained, A guide to dial-up, ADSL and Cable connections
internet connections Welcome to our guide to Internet connections.

In this section we will explain the pros and cons of the different internet connections currently available for home users.
There are various connection types on offer from the different internet service providers, your choice will depend on how often and how you intend to use the internet.

ADSL and cable are types of broadband connection, the term "broadband" only refers to the performance of an internet connection, not to any particular type of connection.

The connection types in this section include:

* Dial-up Connections
* ADSL Connections
* Cable Connections

The Net

The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope that are linked by a broad array of electronic and optical networking technologies. The Internet carries a vast array of information resources and services, most notably the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.
Most traditional communications media, such as telephone and television services, are reshaped or redefined using the technologies of the Internet, giving rise to services such as Voice over Internet Protocol (VoIP) and IPTV. Newspaper publishing has been reshaped into Web sites, blogging, and web feeds. The Internet has enabled or accelerated the creation of new forms of human interactions through instant messaging, Internet forums, and social networking sites.
The origins of the Internet reach back to the 1960s when the United States funded research projects of its military agencies to build robust, fault-tolerant, and distributed computer networks. This research and a period of civilian funding of a new U.S. backbone by the National Science Foundation spawned worldwide participation in the development of new networking technologies and led to the commercialization of an international network in the mid 1990s, and resulted in the following popularization of countless applications in virtually every aspect of modern human life. As of 2009, an estimated quarter of Earth's population uses the services of the Internet.
The Internet has no centralized governance in either technological implementation or policies for access and usage; each constituent network sets its own standards. Only the overreaching

definitions of the two principal name spaces in the Internet, the Internet Protocol address space and the Domain Name System, are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The technical underpinning and standardization of the core protocols (IPv4 and IPv6) is an activity of the Internet Engineering Task Force (IETF), a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise.
