The movement of encoded information by means of electrical transmission systems from one device to another or the transmission of data from one point to another over communication channels like for example the Internet. The amount of data that can be transmitted at time depends entirely on the devices being used and how fast they are and most importantly the amount of data being transfered and type of data being transfered. For example with the Internet, if you transferring big files that contains graphics and large image files, this will slow down the file transfer rate unless you are using a super fast machine.

Data communication has turned the world around because of its convenience it transferring data to different recipients at the same time, now companies do not have to waist time and money trying to get data where it should go and another advantage of data communication is that sensitive data can be restricted to specific people who are suppose to receive the data, although it is very convenient but one still has to make sure good quality security measures are in place in order to protect or rather restrict sensitive data from landing into the wrong hands.

While technology is increasing on a daily basis especially where communication is concerned, it is also extremely important to keep trends on new security technology as well, because some information can be very dangerous to your company if it is not well secured. When I talk of security, I mean software like firewalls and so on, which will prevent external and internal intruders from accessing vital information that might be harmful to the company, and also implement necessary access control measures so that even the information cannot be accessed internally by people who are not suppose to have access this to that specific information.
