A wireless NIC connects to devices using radio waves to transmit data (Wikipedia, 2010). This device is necessary for any WLAN as it is the device that makes wireless possible. An average cost of this device is $60. If a user wishes to connect that computer to another device, he or she will need to utilize a hub, switch or a router to transfer data. According to Bartlett (2010) a hub broadcasts a transmission from one computer to all other available computers. Every device will receive the transmission and have to decide whether the information is for it or not. A switch, however, can memorize which devices are connected to certain ports on the switch, and deliver the transmission to the correct device only (Bartlett, 2010). A router is able to transmit data like a hub or switch, but can also connect to other networks including the internet (Bartlett, 2010).
