What are the primary components of a data communication system?

Data communications: the components.

Your datacom system is an essential part of your business! It enables all your digital information to be stored and moved through your network quickly and securely. It’s a critical part of your smooth-running and effective business operation. We’ve put together a simplified overview of the components in your datacom set-up to help you better understand it’s workings.

The Primary Components of a Data Communication System

Your data communication system relies on a number of primary components that, when working correctly, ensure your data is transmitted quickly, accurately and securely. They include:

  1. Sender: The sender is just that, the source that initiates the transmission of data, such as a computer, a smartphone, or any other device that can send and receive data.
  2. Receiver: Likewise, the receiver is the device that receives the transmitted data, whether it be a computer, a printer, or any other device that can receive and process the data.
  3. Transmission Medium: The transmission medium is the ‘path’ that carries the data from one point to another. The medium can be ‘guided’, or ‘wired medium’, (such as Ethernet or fibre-optic cables), or ‘unguided’, also called a wireless medium, that uses radio waves, microwaves, or satellite comms.
  4. Protocols: Protocols are a set of rules that govern the communication between sender and receiver. They manage the data, so it is transmitted in a consistent and reliable manner.
  5. Modem: The modem converts digital data into analogue signals for transmission over the transmission medium. It also demodulates (or translates) the analogue signals back into digital data at the receiving end.
  6. Switches and Routers: These are networking devices that direct the data through a network. Switches are used to connect devices within a local area network (LAN), while routers are used to connect multiple networks together.

These components should work together seamlessly to ensure secure and reliable transmission of data, with little or no ‘down-time’.
