What You Need to Know About Popular Software – Home Networking Software

December 30th, 2009

A home network is a residential local area network connecting multiple devices within the home. The simplest home networks connect two or more microcomputers that share files, a printer, and a single Internet connection. Connecting a server adds functionality.

Some companies such as AT&T offer their version of home networking to furnish data, video, and voice services to residential customers. These services usually operate over the existing home wiring. The companies install and manage the network, all at a price.

While this article presents some of the software found in home networks we also consider the hardware components. Essential home networking components include a high-speed modem for connection to the Internet. Connection choices include a DSL modem for telephone subscribers and a cable modem for cable subscribers. If you choose an old-fashioned traditional modem, the service could be excruciatingly slow. If you want to connect several computers to the Internet simultaneously you’ll need a router, which may be wireless. Other components include a wide variety of toys such as digital audio players, games machines, and TiVo. You may also consider a print server and for large networks, a network attached storage (NAS) device.

When your home network gets complicated you may consider designating one computer as a home server that handles account authentication, backup, file, printer, and program serving, media center serving, web serving, and more. Interestingly enough the server need not be the most powerful computer in your network. It should have a fast hard drive. An uninterruptible power supply is highly recommended. » Read more: What You Need to Know About Popular Software – Home Networking Software

Wireless Networking

December 28th, 2009

Start wireless networking with making sure that your computer has the right device for wireless internet connections. Most of the new models out in the market today have built-in wireless transmitters but older models need a wireless adapter plugged into a USB port or PC card slot to make it Wi-Fi capable. New wireless adapter models are compatible with the different 802.11 standards.

Upon installation of the wireless adapter, drivers should be installed to enable the computer or laptop to detect existing Wi-Fi networks in the vicinity and then be prompt for connection. Older computers may need a special program to detect and connect to existing Wi-Fi networks.

An existing home network can be converted into a wireless networking access point. On the other hand, if there is wireless networking unavailable for the computers or if the user wants to switch from an Ethernet network to a wireless one, a wireless router with a wireless access point, firewall, Ethernet hub and a port to the DSL modem can be used.

Using a wireless router, you can either connect computers and printers in your network using Ethernet cables or wireless signals. Wireless routers typically provide 30 meter coverage in all directions. Of course, walls and doors can affect the router’s coverage area. To extend the coverage or range of the wireless router, you can use repeaters or extenders.

Default Settings and User Options

The router will run at its default settings upon activation. The user, however, can change these settings depending on his or her preferences using the web interface. The settings that the user can change are the default setting of the service set identifier or SSID which is the manufacturer’s name, the default channel of the router which is channel 6 most of the time and used to minimize or eliminate interference with a neighbours wireless router operating at the same channel, and the router’s security options which has a username and password option.

Wireless Networking Security Options

The last setting is important to people who would like to limit access to wireless networking. For this, you can use any of the three wireless network security options available. WEP (Wired Equivalent Privacy) for example, uses a 64- or 124-bit encryption method that prompts user to provide a password prior to access. The WPA or the Wi-Fi Protected Access on the other hand is an upgrade of WEP included in the 802.11i protocol.

WPA differs from WEP for instead of the bit encryption method, it utilizes TKIP (Temporal Key Integrity Protocol) encryption to safeguard the network data. As with WEP, all users need to provide a password in order to log in to the network. Finally, the Media Access Control or the MAC eliminates the need for passwords and usernames in providing wireless network security. The MAC utilizes the unique MAC address of every computer to determine who is or who is not allowed into the network.
