Multicast is the transfer of messages to multiple destinations simultaneously, using fewer networks. The information is delivered to each of the links only once, and copies are created when the links to the destinations split, thus creating an optimal distribution path. Multicasting reduces unnecessary packet duplication. A wireless network utilizes radio communication, unlike wired networks, …
802.11g is one of the standards used for high speed wireless networks, commonly known as Wifi. This standard was created by the IEEE (Institute of Electrical and Electronics Engineers) in June of 2003 and uses a 2.4 to 2.5 gigahertz radio frequency to send and receive data from one device to another.

On the other hand, by setting up and configuring a router, you can move around with your lap top and surf the web more comfortably. Configuring a router is not difficult; however, people may have …
A message integrity check (MIC), is a security improvement for WEP encryption found on wireless networks. The check helps network administrators avoid attacks that focus on using the bit-flip technique on encrypted network data packets. Unlike the older ICV (Integrity Check Value) method, MIC is able to protect both the data payload and header of …
Wireless networks are those computer networks that use electromagnetic waves instead of wires in order to carry signals over the various parts of the network. Wireless networks which run over other wireless networks often utilize the lower layer networks to provide security and encryption. Stand-alone wireless networks either provide their own security and encryption features …
Wireless networking has grown from only being a tool employed by academia and Fortune 500 companies to being deployed in locations such as McDonald’s, Starbucks, and gas stations for free consumer use over the past decade. Consumers can install a wireless network in the home for minimal cost today, and many home theater set-top boxes …
Cell phone text messages typically use the SMS (Short Message Service) protocol. Most cellular service providers charge fees to send and receive text messages. There are numerous ways to send text messages for free, but they vary among cell service providers. Send Free Text Messages by Purchasing the Right Service Plan Some cell service plans …
A USB WiFi antenna is a device that provides a computer with access to the Internet when in range of a WiFi access point. It also refers to a USB-based wireless adapter that also provides a computer with Internet access but connects to specific wireless routers rather than public WiFi access points. USB WiFi antennas …
