Data transmission technology

Data transmission technology

1. WiFi

   • A system that enables connection over the internet between wireless internet enabled devices

2. USB

   • It is a bidrectional bus which means it can both transmit and receive data. It can also provide power to peripherals

3. Bluetooth

5. Parallel

   • This is older technology used to connect printers over very short distances

6. Serial

   • This is slow technology used for communication devices such as modems. It is also used to connect accessibility devices.

7. Fibre optics

   • A collection of very fine srands of silica glass which use light to transmit data at high speeds.

8. 4G/3G

   • 3G/4G - stands for 3rd/4th generation. It is for accessing the internet at much higher speeds via mobile

9. Ethernet

   • Ethernet is a computer networking protocol.Ethernet can handle the problem of two computers trying to talk at exactly the same time.

10. ADSL

    • ADSL stands for asymmetric Digital Subscriber line. ADSL is the most common type of fast connection to the Internet.

11. Network interface card

    • Network cards are required in every machine connected to the network. They allow the signal from the network to be transmitted to the machine – this could be via a fixed cable, infra red or radio waves.
