VPN is the abbreviated form for Virtual private network. It is the application of networking between computers and devices without the use of physical cables to transfer information from one device to another as is the case of physical networks. With VPN, physical cables are replaced by protocols that simulate a physical network.
Virtual private networks are often applied in cases where remote workers need to connect to devices in the central company computer to retrieve information or to input information or access any one of the devices connected to the network like printers and other peripherals for output. It is also common to see VPN for private usage when a person may need to access their computer from home which is connected to the internet.
VPN technology allows people to work on their office computers from remote locations as if they were already present in their offices. This allows for documents and files to be updated in real time, eliminating the need to make synchronization of documents each time a worker becomes logged onto the system with his laptop. This therefore makes for a greater efficiency in the workplace.
What are the advantages of VPN technology
VPN technology unlike communication that involves fixed lines enables the users to be flexible and to be able to work from any location that they choose as long as they have an internet connection. They are very practical especially for people that work from different states or in different countries where even the thought of connecting offices by fixed leased lines can hardly be conceived.
Moreover there is the issue of security and reliability of the service. VPN technology offers a secure means of connection from to the central network through the implementation of tunneling technology and encryption. Tunneling creates a secure tunnel or path through the internet thereby allowing your information to pass unhindered and protected from disruptions and from those that might try to intercept the information being transferred. The information transferred is further encrypted for double measure, to allow only authenticated users to be able to view and or read the message in the form in which it is intended.
Other uses of VPN technology
The development of VPN technology for companies usually takes a dedicated team of researchers, programmers and network engineers. The cost of rolling out, applying and supporting this technology effectively makes it difficult to be designed and implemented from scratch by individual users. However the obvious advantages of VPN in providing security of data being transferred, and in the provision of privacy by sheltering the IP addresses of their users has allowed the development of companies that offer their services to individual users as well as to companies without the need for the individuals using the package to have the servers and other equipments necessary for the implementation of the technology.
The protection of User IP address and the delivery of a new IP address by the VPN server also allow users to be able to bypass the filtering of information on the internet and to be able to circumvent censorship of internet content.
Therefore individual users can benefit from VPN technology just by signing up with a VPN provider, which will give them access to their servers. From then the user can connect to the internet using their server as the middleman which will also attribute a new IP address to them, enabling individuals to carry out their businesses online in a secure environment.
