Specialist Dental Services (SDS) has an existing Token ring infrastructural that uses IEEE 802.5 standard, meaning that it is a local area network in which all computers are liked in ring or start topology. A token (special bit pattern that travels around the circle, computer catches token to send a message, after attaching massage token is then continues traveling around the network) design is used to prevent collision of date between messages that were send at the same time. In the token ring infrastructure data rate transfer is 4 to 16 Mbps, with shielded and unshielded twisted-pair cabling of 1,2,3 IBM types to wire a token network.
An Ethernet is different, since whenever any computer needs to send data, it does not need a token to send a message, any computer can send data at any time. In Ethernet data is send in form of packages, to control …show more content…

The main difference of a WiFi to Token ring and Ethernet networks is that it does not require a physical media from the source to the receiver to create a network and establish a connection, although WiFi would not compete with speeds of data transfer of an Ethernet. A WiFi connection is made by using a wireless adapter(that converts digital information to radio waves and back with antenna) to create a hotspots that allow access to internet service. WiFi technology is using 802.11 networking standards (802.11a, 802.11b, 802.11n etc. ) that will depend on needs for the user. In wireless networks there are two logical typologies that are use, a star and point-to-point (devices connect directly to each other and do not need access point device to communicate), in general WiFi speed is on average 20Mbps, however it can vary on many factor like distance between users and source or media radio waves has to travel through on the way to the user and
