Remote access can be established via a line that runs between a computer and a company’s local area network (LAN). A connection can also be established between a company’s LAN and a remote LAN using a dedicated line. This type of line provides faster speeds but has the drawback of being more expensive.
Another method for performing remote access is by establishing a VPN, a network that usually uses the Internet to connect remote sites and users together. This type of network uses encryption and tunneling to access a company’s network. This can be a great choice for a relatively small organization. Other means of establishing remote access include the use of an integrated services digital network, wireless network, cable modem or digital subscriber line.
To establish a remote connection, both the local machine and the remote computer/server must have remote-access software. Alternatively, there are service providers that offer remote access via the Internet.
