Web browsers use TCP when they connect to servers on the internet. It is also used to deliver email and transfer files to different locations. AppleTalk AppleTalk is a relatively cheap local-area network architecture built into Apple Macintosh computers and laser printers.

It provides a datagram service to an IP host. UDP is an unreliable service that provides no guarantees for delivery and no security from duplication. It can also be used between two wireless clients.

There are quite a few different specifications in the The second transmitter and receiver antennas allow increased data through increased range.

This operates on the 5GHz frequency. Infrared Infrared in mobile phones uses infrared waves to send data from one mobile phone to another. Infrared works to different to other wireless sending media because both phones have to be in very close proximity and in line of each other.

Both sensors must Btec ict level 3 facing each other in order for the infrared to work. It is a faster and more adapted version of 3G. There were pre-4G technologies available by network operators but it would often fall short of Mbps FDDI networks are token passing networks and support data rates of up to Mbps.

Each node on the network checks the token as it passes through to see if the data is connected to that node. Bluetooth Bluetooth is a wireless technology for exchanging data over a short distance. The Bluetooth chip is mainly used in computers, mobile devices and digital cameras.

Bluetooth uses a special radio frequency to transmit data. It is very secure and can connect up to eight devices at any one time. Factors affecting range and speed of wireless technologies Electronic Interference Wireless networks commonly use the 2.

When there are other nearby devices such as mobiles and tablets emit this frequency, they will interfere with the networks signal.

Once the interference stops the network returns to optimal speeds. Physical Obstacles Physical obstacles can cause interference for wireless signals. When the data is being sent through the signals through large obstacles, degradation occurs because the object absorbs the signals and scatters it.

Thicker objects such as thick walls absorb a larger portion of the signals. Bandwidth Use Network traffic can affect the performance of other devices attached to the network. Bandwidth determines the maximum data rate that can be transferred over a network. Before DNS was created, computers used simple text file maintained by the network information centre that mapped names to IP addresses.

By having DNS, when searching for webpages all you would have to remember is www. With dynamic addressing, a device can have a different IP address every time it connects to the network. It defines how messages are formatted and transmitted and what actions web browsers should take in response to various commands.
