Email Speaker 3G - 2BandwidthThe amount of data that can fit through an Internet connection. You can compare it to a ten-lane motorway which can fit more cars on it than a four-lane motorway. Bandwidth is measured in bits per second (bps). This indicates the number of bits of information that can fit down the line in one second. Kb or Kbps means thousands of bits per second; Mb or Mbps means millions of bits per second.
- 3BroadbandA high-speed connection to the Internet.
- 4DongleA small piece of hardware that connects to a computer and has uses including data storage and picking up Bluetooth and 3G signals. A dongle may be portable like a USB pen.
- 5HotspotA venue that offers a WiFi Internet connection. Many are located in hotels and restaurants and lots of them are free.
- 6Internet service provider (ISP)A company that provides Internet access to its customers.
- 7IP (Internet Protocol) addressThe personal address of your computer (just like your home address), so that servers know where to send the information you have requested.
- 8LatencyThe time delay between the moment something is initiated and the moment it becomes detectable.
- 9NetworkDevices connected together to allow communication and exchange of data.
- 10ProtocolA set of rules used by computers to communicate with each other across a network. Without protocols, computers would not be able to communicate effectively.
- 11Third generation (3G)Third-generation wireless communication allows high-speed wireless data transfer.
- 12VoIP (Voice over Internet Protocol)This technology is used to make telephone calls via the Internet, usually at a cheaper cost.
- 13WifiWireless fidelity. It is similar to Bluetooth in that it is used to exchange data, but the signals can travel further distances.
- 14BluetoothAllows the exchange of data over short distances from fixed and mobile devices. In order for devices to communicate they must be able to understand the Bluetooth rules (protocols).
- 15MultifunctionalHaving the ability to do many different things using the same device.
- 16PeripheralsExternal devices connected to a computer, e.g. printer, microphone.
- 17Smart phoneA phone offering advanced features, e.g. the ability to send emails, surf the Internet.
- 18Sat navA device, usually used in a car, that gives directions based on information received from a series of satellites.
- 19GeotagTo attach the exact geographical coordinates of longitude and latitude to a digital image, giving the location of where it was taken.
- 20Digital Device Factors to consider-Battery life
-User interface
-Connectivity
-Security
-Reliability and support services offered
-Storage capacity/ memory
-Convenience (size and weight etc.) -Compatibility with other devices
-Speed of Internet connection and processor
-Purpose (gaming, playing music, watching HD films)
- Cost (device, internet service provider and maintenance) - 21ProcessorThere is a processor in all digital devices, from desktop computer to mobile phones. It controls all the functions of the device. There are specialist microprocessors for different devices.
- 22Internal memoryWhile the microprocessor is working it needs to store the program instructions and data in its internal memory.
