VPN is pronounced as separate letters and is short for virtual private network.
VPN, or virtual private network, is a network that is constructed by using public wires — usually the Internet — to connect to a private network, such as a company’s internal network. There are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted. A VPN is designed to provides a secure, encrypted tunnel in which to transmit the data between the remote user and the company network. The information transmitted between the two locations via the encrypted tunnel cannot be read by anyone else because the system contains several elements to secure both the company’s private network and the outside network through which the remote user connects through.
virtual LAN, a network of computers that behave as if they are connected to the same wire even though they may actually be physically located on different segments of a LAN. VLANs are configured through software rather than hardware, which makes them extremely flexible. One of the biggest advantages of VLANs is that when a computer is physically moved to another location, it can stay on the same VLAN without any hardware reconfiguration.
The Advantages Of Virtual Private Networks
A VPN (virtual private network) is a secure network that utilizes the internet to connect online users and remote servers together. VPNs are most commonly used to allow employees to securely connect to corporate servers from remote locations. By requiring an employ to connect to a server via a vpn, a corporation can rest assured that their confidential data is secure.
Nowadays, a company can incorporate a virtual private network into their intranet configuration, allowing them to grant remote offices secure access to central servers. In comparison to other technologies, a VPN service has many advantages and featured below are three of the main benefits of VPNs.
1. Saving Money
By using a VPN a business can save money by avoiding the expense of leasing a long distance line and the high charges associated with international calls.
2. Security, Reliability and Speed
Virtual private networks provide companies with a fast, secure, reliable way to share data between employees. Companies that would benefit most from a VPN are those who hire traveling sales personal and those who have multiple locations around the globe. VPN are encrypted, so only users who specifically have access to the network will be able to read data. Anyone who intercepts data on the network will be unable to decipher the data due to the security of the encryption used by good VPN providers. Consequently, virtual private networks are ideally suited to companies that have a lot of confidential data on their servers.
By connecting to the internet through a VPN, an internet user can not be linked to a specific IP address or physical location. Therefore, a VPN is perfect for those who wish to prevent others from tracking their online activity.
The three advantages of VPNs highlighted above outline some of the most important benefits of using a virtual private network.
