The initials “VPN” in the computer industry stands for “Virtual Private Network” and this is actually a physical framework constructed using the actual PC and its connecting wires to effectively establish several nodes of computing machines within a network. This system uses several advanced security measures such as data encryption techniques to ensure that only those authorized users are able to access and view the associated data found on the established network. This type of network is basically what is meant when mention is made as to a virtual or a private connection.
VPN is one form of “WAN” or the “Wide Area Network” and it is capable of supplying a network of connectivity which can stretch for very wide physical distances such as through the use of the World Wide Web or by use of an intranet. Both of these are commonly employed network capabilities established by major companies and corporations for use by its staff and executives. Data file sharing, voice or video conference transfers as well as other network services similar in nature are made possible by way of the VPN.
The VPN is able to work both in the private mode as well as in public networks such as the internet. This is accomplished though the use of a method referred to as “tunneling”. While “tunneling” still makes use of the same hardware infrastructure of the computer system such as the existing intranet or internet link up features it has its own unique manner of operation as well. As mentioned previously, it has the capacity to protect your private connection and thus your personal data through several effective security systems and safety mechanisms. Security for major corporations is of prime concern when establishing these data transfer systems. There is no acceptable excuse for weak or ineffective security when it concerns personal and business data thus only those proven methods and systems are acceptable.
VPN can be employed chiefly in three different types of communication modes. The first mode is merely for accessing the internet itself. The LAN to another LAN networking is the second communication means and lastly it is able to function within a controlled environment such as a privately set-up intranet structure. Just recently, many corporations and companies have begun to explore the possibility of increasing mobility among its key executives and important staff members. With this move towards a mobile structure the VPN has taken on a new and elevated position of importance. With the vast development in telecommunication the VPN function has proven to be very useful for people that desire to remain connected even when considering the huge differences involved in physical distance. As a result of these advanced planning initiatives productivity is not compromised by distance in the least.
