A Data Network can be derived as the communication process triggered between two or more points (locations) that enables orderly transmission and receptive of data (digitized details), such as letters, documents, electronic mail (email) and other similar digital documents. The uniqueness about the network is that it is configured to transmit only data.

There are two types of Data Networks in operation globally. They are typically the Private Data Network and Public Data network.

Private Data Network is known as the ‘Local Area Network’ (LAN) that is essentially designed to transmit data between the various divisions within a given entity, within a location such as a corporate establishment or company. Each of the divisions within the company is termed as a ‘node’ that communicate with one another via a common server that functions the repository for all data files, documents that are used throughout the organization. Furthermore a private data network can be utilized for data sharing between several organisations that are part of the same group of profession or industry. Network with such caliber are call the Virtual Private Network (VPN) that resides on a master server that is facilitated through a communication carrier.

Public Data Network on the other hand is a total contrast to the private data network by being widely accessible to both residential and corporate clients of a given carrier network across a multi geographical area. Public Data Network typically engages multiple servers and connections to the network through several different processes. Generally network of this caliber requires to subscribe into a major communication carrier like telephone or satellite connections on a monthly or annual basis to establish access credentials that will allow the consumer to access authorised portions of the network and engage in transfer or transmission of valid and valued data. Most prominent activities being the ability to retrieve stored documents, share the documents, creation of backups of important data files, archive historical details and other routine functions.
