2. Topics covered What is Home Networking? The reasons for setting up a Home Network.
Types of Home Networks and choosing your technology.
Buying and installing the hardware.
Configure the system and get the hardware talking to each other.
Address any security issues to keep your Network safe.
3. Home Networking Share a single printer between computers.
Share a single Internet connection with all the computers in your house.
Access shared files on any computer in your house (Pictures, MP3s, Documents & Data).
Play games that allow multiple users at different computers.
Send the output of a device such as a DVD player or Webcam to your other computer(s)
4. Types of Home Networking Sneaker Net The use of Diskettes, CD-R/CD-RW and USB thumb drives. Inexpensive, but inconvenient especially when the computers are not on the same floor.
Link computers through the phone lines.
Link computers through the power lines.
Link computers wirelessly by WIFI.
Link computers through wires by Ethernet

9. HomePNA networking HomePNA does have some drawbacks, though.
Requires a phone jack close to each computer.
Even though it operates at a very reasonable 10 Mbps, it is still 10 times slower than fast Ethernet (100 Mbps)
A physical limit of 1,000 feet (304.8 m) of wiring between devices
The overall area of coverage should not exceed 10,000 square feet (929 m2).
Occasionally, HomePNA will not work on the existing wiring. Reports of voices sounding "funny" or of a lot of noise on the phone once HomePNA is installed.
Therefore, if you are going to be sending huge amounts of data between your computers, you may want more speed. There is a physical limit of 1,000 feet (304.8 m) of wiring between devices, and the overall area of coverage should not exceed 10,000 square feet (929 m2).

21. The radios used in WiFi are similar to the radios used in $5 walkie-talkies, with the ability to transmit and receive.
They convert the digital 1s and 0s into radio waves and back into 1s and 0s.
22. There are currently three different WiFi systems:
The 802.11b and 802.11g standards transmit at 2.4 GHz, while the 802.11a standard transmits at 5 GHz. The higher frequency allows higher data rates.
23. There are two coding techniques:
The 802.11a and 802.11g, known as orthogonal frequency-division multiplexing (OFDM), provide higher data rates
The 802.11b, which is called Complementary Code Keying (CCK).
24. WiFi has the ability to change frequencies:
802.11b cards transmit directly on any of three bands.
The 802.11a and 802.11g split the available radio bandwidth into dozens of channels and frequency hop rapidly between them. The advantage of frequency hopping is that it is much more immune to interference and allows dozens of WiFi cards to talk simultaneously without interfering with each other.
25. 802.11b can handle up to 11 megabits per second, although 7 megabits per second is more typical, and may fall back as low as 1 or 2 megabits per second if there is a lot of interference.
802.11a and 802.11g can handle up to 54 megabits per second, although 30 megabits per second is more typical.

36. Once you have the hardware installed, you are ready to configure your network.
The first configuration step is naming the PCs in the network. Before your computer can become part of a network, it has to have a name and a workgroup.
Each computer in your home network needs to have a different name, and they all need to be in the same workgroup. Ethernet Networking Configuring the system Naming the PC
37. Here's how you can name your PC and create a workgroup:
In Windows XP, click the Start button (bottom left hand corner) and select the Control Panel.
If not already in the "Classic view", select the Classic view option (upper left corner of the window - you can switch between the classic view and the category view).
Click on the "System" icon.
Select the "Computer Name" tab.
You will see that the computer has a "Full Computer Name" and a "Workgroup". Click the "Change" button to change them.
In the first box, enter the name you wish to give the computer. You can name it anything, but each computer in your home must have a its own unique name.
In the second box, enter the name you plan to use for the workgroup -- make sure all of the computers have the same workgroup name. You may want to write it down to make sure that you enter the exact same workgroup name on each computer in your home network Ethernet Networking Configuring the system Naming the PC
38. In Windows 98/ME, move the mouse pointer over the Network Neighbourhood icon on the desktop and click the right mouse button once.
Select Properties from the menu. The Network Properties window will pop up, listing information about the network adapter(s) and protocols installed on that computer. Ethernet Networking Configuring the system Naming the PC

42. File Sharing Windows XP In Windows XP, click the Start button (bottom left hand corner) and select the Control Panel.
If not already in the "Classic view", select the Classic view option (upper left corner of the window - you can switch between the classic view and the category view).
Click on the "Network Connections" icon.
Right click on the icon under the "LAN or High Speed Networking" option. Select Properties from the menu that appears.
You will see that the computer has a "Full Computer Name" and a "Workgroup". Click the "Change" button to change them.
Select the "Advanced" tab.
Click on the "Allow other network users to connect..." option.
Follow the directions in the dialog that appears.
43. By default, the ICS components are not installed on your computer. You only run ICS on the computer that is actually connected to the Internet:
44. File Sharing Windows 98
45. While file and printer sharing are still relatively easy on either operating system, Internet-connection sharing using only software can be a good deal trickier.
In most cases, if you are sharing a high-speed connection with several computers in your home (and especially if you are doing it wirelessly) it is easier to purchase a wireless hub/router and let it do the connection sharing for you. Lynksys' or Netgear's wireless hubs/routers are inexpensive, very easy to set up and also have the added benefit of providing a hardware firewall to protect your network.
