Tamanna Mimi CIS 240 Professor Earl Robinson, JR February 4th, 2017 “Five Technology That Uses Network” A network is a group of computers and other devices connected by some type transmission media. There are various kind of network available nowadays. A network can be as small as two computer connected by a cable at home or larger like several thousand computer connected worldwide via cable lines, phone lines, and cellular links. The use of networks has lots of advantages. Networks enable multiple users to share devices and data. For example, instead of buying 20 printers for 20 people, a company can buy one printer and have 20 people share it over a network. Here are five technologies that uses network: scanner, printer, Bluetooth,…show more content…
There are some computers that have Bluetooth network to allow printing from smartphones, tablets, etc. All recent version of Microsoft windows uses File and Printer Sharing feature to allow printer connected to one PC to share with other PCs over local network. Another way network printing is cloud printing. Cloud printing can be done over internet connected computers and phones to a remote printer. Off course this requires a printer to be connected with internet network. Another device that works on by using network is Bluetooth. Everyone is failure with Bluetooth. It is pretty much in every cellphone, computer, cars, and etc. the Bluetooth works by transmitting low frequency radio waves of about of 2.45 gigahertz. There are other devices that uses the same frequency like a baby monitor. the Bluetooth is designed such way that it won’t interfere with other devices using the same frequency. Bluetooth send very low and weak signals of about 1 milliwatt to avoid interference. A Bluetooth can connect to up to eight devices in one time. Bluetooth uses a technique called spread-spectrum frequency hopping. The spread-spectrum frequency hopping makes the Bluetooth rare for more than one device to be transmitting on the same frequency at the same time. in this techniques Bluetooth uses 79 random frequencies within the range and changes from one to frequency to another in a regular basis. The Bluetooth transmitters changes frequency
