TAX-AIDETAX-AIDE1NETWORK BASICSScope of PresentationApplies to TaxWise Online (TWO) configurations
Overview and configurations of networking for TWO
Covers necessary terminology, various network configurations, and provides references for more detail
TAX-AIDE2NETWORK BASICSBenefits of Networking TaxWise OnlineConservation of Resources: Sharing of Input/Output Devices (such as printers).
Backups: No Backups are required
Internet Access: Networking allows Internet access for all network computers via a single routerNote: it isnt even necessary for other Tax-Aide computers to see each other
TAX-AIDENETWORK BASICSTerminology - Local Area Network (LAN)Definition: A group of computers and network devices that share a common communications connection and typically share the resources of computers or a server within a small geographic area (an office, office building, organization).
A Tax-Aide local area network may serve as few as two or three users or as many as 20 on a Windows 7 Professional network.
TAX-AIDENETWORK BASICSTerminology Wide Area Network (WAN)Definition: A long-distance communi-cations network that covers a wide geographic area, such as a state or country. Example: The Internet is the worlds largest WAN
TAX-AIDENETWORK BASICSTerminology - IP AddressesFor computers to communicate with each other using a router, they must have a unique identifier that identifier is the IP AddressSimilar to a telephone networkTo communicate sensibly, there must be a unique IP Address in the format 127.0.0.1This IP Address is assigned automatically by network router always unique on the NetworkDevices such as printers can also be assigned a specific IP address called Static IP Address.Devices can be assigned random IP addresses called Dynamic IP Address
TAX-AIDENETWORK BASICSConnection OptionsNetwork switchActs much like an extension cordAllows more computers/devices to connect to a router by adding more portsCant connect to other networks or the InternetNot software configurableRouterContains a network switchAlso provides a bridge to other networks and the InternetHighly software configurableCan be Wireless or Wired or Combination
TAX-AIDENETWORK BASICSRouterA Router is the device used to create a computer Local Area Network (LAN) when connection to the Internet is required.Router default settings use Dynamic IP Address to automatically assign an IP address to each connected computer or device to create a network.Network printers can be connected to the routerResources can now be shared among devices
TAX-AIDENETWORK BASICSRouterRouter adds the capability to attach a network or wireless printer to the LAN rather than having a shared printer connected to a workgroup computer.
Network printerPrinter has a network portConnects directly to the routerMore responsiveDoesnt take resources from a computer
Provides wireless WPA security on the Network

ICS is found in Windows Networking properties In this case, the ICS connects to the host Wireless networkComputers can connect directly to ICS computer to acquire Dynamic IP Address from the computer Router can be configured as wireless Access PointShared printer(s) can be usedHard-wired or wireless network printer(s) can be used

TAX-AIDENETWORK BASICSRouter WarningRouters that are suitable (and affordable) for the Tax-Aide program are technology challenged
Not meant for heavy usage, consequently theyre severely limited in the number of connections they can route especially, when they are configured to use WPA security which is required by Tax-Aide
The routers are prone to overheating and dropping connections when 8 to 12 computers are connected
Keep them cool and in an open space
