Data transmission technology

1. What is a USB connection?

   • USB (Universal Serial Bus) is the most popular connection used to connect a computer to devices such as digital cameras, printers, scanners, and external hard drives.

2. What is a Bluetooth connection?

   • A standard for the short-range wireless interconnection of mobile phones, computers, and other electronic devices.

3. What is VGA?

   • Abbreviated VGA, Video Graphics Array is a standard type of connection for video devices such as monitors and projectors.

4. What is HDMI?

   • Short for High-Definition Multimedia Interface, it is the first industry-supported uncompressed, all-digital audio/video interface

5. What is Display port?

   • DisplayPort is an interface for digital displays, particularly computer monitors. It was developed by the Video Electronics Standards Association (VESA) as a high-performance replacement for other display modes such as VGA (Video Graphics Array) and DVI (Digital Visual Interface).

6. Parallel Port

   • A connector for a device that sends or receives several bits of data simultaneously by using more than one wire.

7. Serial Port

   • A connector by which a device that sends data one bit at a time may be connected to a computer.

8. WIFI

   • A facility allowing computers, smartphones, or other devices to connect to the Internet or communicate with one another wirelessly within a particular area.

9. ADSL

   • Asymmetric digital subscriber line (ADSL) is a type of DSL broadband communications technology used for connecting to the Internet. ADSL allows more data to be sent over existing copper telephone lines (POTS), when compared to traditional modem lines.

10. 3G/4G Connection

    • A mobile communications standard intended to replace 3G, allowing wireless Internet access at a much higher speed.

11. Ethernet

    • A system for connecting a number of computer systems to form a local area network, with protocols to control the passing of information and to avoid simultaneous transmission by two or more systems.

12. Fibre Optic

    • Consisting of or using thin flexible fibres with a glass core through which light signals can be sent with very little loss of strength.

13. Network interface card

    • A network interface controller is a computer hardware component that connects a computer to a computer network. Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.
